TDU and Logitech G25 problems

[odraciRRicardo]

Hi, I'm having some problems with G25 when on TDU.
The performance is ok, around 40/50fps but whenever I move the wheel the frame rate drops to something like 10/20fps. The more violently I move the wheel more accentuated the frame rate drop is. It doesn't matter if the car is moving or stopped. This problem doesn't seem to appear when I start the game, just after a little while.
Anyone having the same problem? Any solution?
Thanks.

[dickij]

post your specs

[odraciRRicardo]

Why? The problem only appears when i move the wheel.
But...
X1900XT 256Mb
AMD 64 3200+ @2.4GHz
1GB DDR
Soundblaster 4

I'm running at 1280x1024, High settings, HDR, aa 4x, af 4x, but problem appears no matter what settings I use.
And BTW, no matter what settings I use I get roughly the same performance, so this game is highly cpu dependent...

[SJ_INSTG8R]

Oddly enough I am ACTUALLY sorting the very same issue out with another fellow SJ member(I am currently reading thru his Everest Report to see if I can see anything obvious)
If I come up with something I will most definitely post it here for you, I hope if you come up with something(or anyone else for that matter) you will post it here.(it is an odd issue I have tried to sort thru with him before but now I am making a serious effort so figure it out)
I will keep you posted

[SJ_INSTG8R]

The only common thing I see from your specs and his is that you both have Soundblasters and ATI GFX cards.
I will first suggest you try disabling the Creative Gameport in Device Manager(find it under Sound and Audio)see if that helps, I will also suggest this to him as well.

[odraciRRicardo]

If I come up with something I will most definitely post it here for you, I hope if you come up with something(or anyone else for that matter) you will post it here.
I will be eagerly waiting :)

Will do...

Thanks.

If that's a SoundBlaster Audigy 4, I've got one as well - no problems with the G25. I've got an Nvidia card though (7900GTO), and an Intel Core 2 Duo processor.

[odraciRRicardo]

I realized now that my sound card has no gameport so i cannot disable it :)
Also, i noticed i hadn't the avivo drivers installed, but after installing them everything is the same.
Any idea?

[SJ_INSTG8R]

Well as I said my member has had this issue since he got his G25 quite some time ago(he is an avid sim racer so this has been very frustrating for him)I have tried to go thru this with him before,but he does have a rather aging PC. After going thru his Everest report I didnt see anything that stuck out(he left it with me last night and went to bed)
When we can get together I will go thru some stuff with him more in depth(now that I have all the info on his hardware)

It seems to me(just guessing at this point) that is looks like a Polling Rate issue because it seems all is well UNTIL you move the wheel(then it basically slows everything down)I intiailly thought because of the age of his PC he may not have any USB 2.0 hubs(that wasnt the case)

I will try to step by step thru some of my more common hardware fixes as soon as I can(of course he is very frustated being forced to use his keyboard or joystick to drive considering the wheel he has in this game and any other game as well)

Of course IF I nail this down I wont forget to post the solution.

Thanks & ~COTI!~ :salut2:(Cya on "The Island")

[Nekobaka]

So, is this a common problem then or TDU specific? From the last post I rather get the feeling your friend has this issue with other games too?

[SJ_INSTG8R]

So, is this a common problem then or TDU specific? From the last post I rather get the feeling your friend has this issue with other games too?

Yes he has this issue since he got it and it basically sits and gathers dust(he returned his first one and tried a 2nd, same result, it is some sort of hardware issue but he's in the Netherlands and Im in Norway so there is only so much I can do to help him on the "interweb"

I have a few theories and things I want him to try(I cant really recall how in depth I went with him the first time we tried) but we are always on our comms when we play anything(we Fly IL-2 and race the "usual suspects" racing sims together) so we will track down the issue eventually.
He just got TD:U yesterday so of course he tried to give it another try to the same results. SO we will got thru it again from the top this time and get him sorted.Also I only got mine a month or so ago and had a DFP previously, now I have a G25 so I am familliar with its working so I have a better base to work off of as well.

Will post any results as soon as I have some.

[odraciRRicardo]

Yes he has this issue since he got it and it basically sits and gathers dust

That's another issue them, I only got this problem with TDU, I play GTR2, GTL, Race, rFactor, LFS, RBR and have no problem at all with those.

[rhino_wjb]

That's another issue them, I only got this problem with TDU, I play GTR2, GTL, Race, rFactor, LFS, RBR and have no problem at all with those.

Ditto.

The frame rate chops up bad for me, yet I have all the others you mentioned (apart from GTL) which run fine, no problems.

Good luck with getting this fixed!

[SJ_INSTG8R]

That's another issue them, I only got this problem with TDU, I play GTR2, GTL, Race, rFactor, LFS, RBR and have no problem at all with those.

Well sadly he has it in everything GTL, GTR2 rFactor and now TD:U he does have a rather aging machine but I'm stumped so far as to what the issue is. I made him do a very thorough tidy up tonight and had him remove a bunch of old device entries. He removed one HID Compliant Game Controller entry and it locked up his PC. I am thinking this is the issue. But I sent him off to D/L a decent Reg Cleaner/Sys Optimizer Trial and I havent spoken to him since so I will update you when I speak to him again.

[odraciRRicardo]

Hi SJ_INSTG8R, any news?
I saw the other thread were you told that the problem could be related to having used another wheel before. Just want let you know I'm playing in clean XP install were I never used another wheel, I even tried it in my Vista partition and it's still a no go.
:noooo:

[Maestr0]

Seeing that I also have the G25 and not having any problems at all, I'll post my specs as well:

AMD 4200+ dual core
2gig DDR400 ram
XFX 7900GT 256mb ram running 94.20 drivers (awesome drivers for the 7000 series of cards by the way...giving me between 5 and 15 fps extra. It is the last driver set that was released without any support for the 8000 series.)
Creative Audigy soundcard

I also have the latest logitech drivers installed for the logitech controllers. I also have only one controller connected at present as I do not really enjoy driving the bikes. Running Windows XP professional SP2 with all latest updates installed as well.

Detail settings and video settings:
1280x1024
4XAA
High Detail
HDR (disabled)

Wheel is set to 75% sensitivity, Linearity is set to 100%. Force feedback strength isn't very high as this wheel is damn strong. I am also using combined pedals for this game as it just works better.

Let me know if I can be of any more assistance.

Regards
M :)

hi guys,

I'm responsible for Devices on TDU.

First, let me apologize about all the problems you have. And also let me tell you that i never encouter those problems during the development.

We have now some time to correct those problems.

1st thing i will try, is to add a slide to reduce the FFB update frequency. Maybe i try to send to much FFB action to the wheel and maybe it is flooded... even if i never add the problem myself. ( i use all logitech wheels during development ).

so.. i'm just here to tell that i'm currently working on all the devices problems.

cheers,

[xtermin8or]

Yep same here too, I have a Logitech G25 , and i play perfect in everygame,

GTR2, all nFS's etc... with high detail and i play TDU on everything high with 1240X... and i have 1GB of ram , amd 64 3200 cpu and X800XT PT vga card.

I get arund 30-35 fps and as soon as i put the wheel in it goes down to maybe 8?

Please fix this problem... :noooo:

[zstef]

Intel core 2 DUO / HT CPU related problem?

[Anacro]

I have the same issue with the G25 Wheel, laggy but unplug it and it works ok. All other wheel games work fine.

[Dutch_Bart]

I've had problems in the beginning with the G25 as well, I've found out that when the forces are set above 100%, the game will get laggy as hell, when they are set at 100% there is no problem

[SJ_banger]

i have a g25 no problems here.has anybody try sending an EVEREST REPORT TO Atari support.

you can get the everest info here. 30 day trial.

Hi everyone,

I have the same issues with my G25 as most of you are having.
All other beforementioned racinggames work sweetly, only in TDU I'm experiencing problems.

I've posted about this in other threads on this forum a while ago and many many people seem to have this problem with basically any kind of FFB racing wheel. Ofcourse also many people have no problems at all with the same types of wheels.

I'm beginning to notice a pattern that frightens me :P I saw someone else suggest it too on a thread around here somewhere.

It seems that everyone who has these problems with their wheels has a single core processor, and people with dual core processors dont seem to have this problem at all.

I'll post my own specs here again.

P4C800-Deluxe
P4 (R) 2.8Ghz HT
1024 MB PC3200 DDR CORSAIR TwinX CAS2 (2048 as of tomorrow but I doubt it will help)
Sapphire ATI X1950Pro 512 MB AGP
WD Raptor 36GB HDD SATA 10.000 RPM
Epson TW-20 HDTV-Projector
Trackir 4 Pro
Logitech G-25

Can anyone confirm or deny the theory I'm proposing here? Anyone with Dual Core who has these probs or anyone with single core who doesnt?

Thanks in advance for any reaction!

:salut2:

[xtermin8or]

my friend plays tdu on his computer with a AMD 64 3200+ fine with a Logitech MOMO, and last nite i tried to play mine again and it worked for around 2 minutes then it started laggin bad and i have a 3200+ aswell...

Very annoying..

[matthijsborgdorff]

Ok, so you have single core and have problems, and your friend has same single core but no problems.

Well so much for my theory I guess :p

I'm glad too, coz I have a single core processor and I'm not about to update my entire system just for this game.

Thanks for your response!

Just been having the exact same problems with my G25 and TDU on a brand new PC. I have found that unplugging the MS Sidewinder 2 has resolved the problem though. Worth giving it a go if you've got more than one controller plugged in.
Just got to work out now how to get the gear shift to work with the 6 speed shifter rather than the paddles. I've tried H shift on and off and I've set the six (well, 8 if you include reverse and 7th) gears to the separate controller but for some reason, nothing, paddles only.

That is VERY wrong to have it set up like that. by having EVERYTHING at 100% you are basically overriding ALL FFB in TDU(or any other game for that matter)
I advise all my SJ Members to not even RUN the profiler PERIOD(and everyone else in fact)
Basically the ONLY thing you should have on is the Overall Strength(at 100% of course) but all else should be at zero and unchecked) and make FFB adjustments within the games settings. The intent of those other settings is to add "fake" FFB to older games that don't not have proper FFB support.


http://img407.imageshack.us/img407/4606/g25setupcpva0.th.jpg (http://img407.imageshack.us/my.php?image=g25setupcpva0.jpg)

The "Proper" way to set up your FFB settings(of course Rotation is to taste) but this is ONLY thru the CP and not running the useless Profiler (IMHO)
There is no need for the Profiler unless you say need to remap keys that arent seen in the game and again all the other FFB settings are for games with poor/old FFB so you use the rest to add them back in.

If the Car has a Sequential Gearbox(paddles) you must use the paddles(Lambos for instance) IF the car has a stick shift you must use it.
But you were very correct about the 2nd controller causing slowdowns as this game has issues with multiple controllers(a bit odd to me but maybe it will get sorted)Also it has been found out that if your Snd Card or MoBo has a Gameport it is advisable to disable that as well if you can as it seems the game looks at that too and can also cause slowdowns

[Dutch_Bart]

well, what can I say, it works fine for me, normally I run games with all forces set to max, that works terribly in tdu, so I use game specific settings for tdu, and haven't got any problems with it at all

[SJ_INSTG8R]

Well seeing as you have been running it that way(everything at 100%) thats WHY it runs terribly in TDU as its basically wrong and in other games you wouldnt know the difference as your overriding all the FFB the game is offering you and substituting with forced "Fake" FFB ....(trust me mate I have done ALOT of research on Logitech wheels and their FFB implemenations and FFB in general)I can post you links galore including Logitech FAQs supporting what Im telling you.

Do yourself a favour and try it my way and maybe you'll see the light(trust me your not the first sceptic and wont be the last) But I am the FFB Guru over at SJ and even our fastest drivers who have been on the fence about my setups have come back to me with nothing but praise and faster times ;)

[turbine_2]

If the Car has a Sequential Gearbox(paddles) you must use the paddles(Lambos for instance) IF the car has a stick shift you must use it.

True, but this was the hire Audi and the basic Audi model that I bought. As it happens, I deleted that profile (mostly because it was the one where I had suffered the stuttering problem and didn't like it much) and created a new one, and the new one works the stick shift just fine.

Thanks for the advise though.

[Dutch_Bart]

I never said it ran terribly on my system, that's your conclusion, I've tried your suggestions, but I can hardly tell the difference, aside from the fact that I can stop running it from the profiler..

and the game runs as good as it has run before I changed the settings ;)

[SJ_INSTG8R]

"normally I run games with all forces set to max, that works terribly in tdu,..."

I never said ANYTHING about it running terribly on your system either..... rolleyesa
I am just pointing out the FACTS about the Profiler and your choice of FFB setup nothing more. If you like to run it full tilt with "Faked FFB" thru the CP OR the Profiler(its all the same thing and why I say why waste resources on the Profiler) thats your choice. You want to get testy with me go right ahead and forget I even tried to suggest to you the way to properly set up FFB with your wonderful wheel......

But let me leave you with a quote from the Logitech FAQ: and I highlighted more important bits.

What is the difference between the settings within the Profiler and the Control Panel?

*

First, a few acronyms:

CPS = Control Panel Settings

GPS = Global Profiler Settings

GSS = Game Specific Settings (per profile)

GS = Game's settings (within the game itself)

*

The CPS and GPS are in synch. Change it in one place, check in the other place and they will be the same. This value is applied on top of any game force.
*

If you have a GSS, this will override (= replace) the CPS/GPS settings.
*

So, there's only one single value in the software that is applied - either CPS/GPS (for games without profiles, or games with profiles that don't have a specific settings) or GSS (for games with profiles with specific settings set).
*

Whichever setting applies, it will be used to scale forces up or down that the game produces. The recommended thing is to leave the settings at 100% in software, and correct to your taste in the game (as the game sometimes allows much finer control - see for example Need For Speed, which allows you to change the different force types individually).
*

The settings should come into play if the game in question has no or insufficient control (GSS), or if you end up thinking that your wheel is generally too strong/weak in all games (CPS/GPS).

[CraigLewis]

Hi, I'm having some problems with G25 when on TDU.
The performance is ok, around 40/50fps but whenever I move the wheel the frame rate drops to something like 10/20fps. The more violently I move the wheel more accentuated the frame rate drop is. It doesn't matter if the car is moving or stopped. This problem doesn't seem to appear when I start the game, just after a little while.
Anyone having the same problem? Any solution?
Thanks.

I have something that you may want to take a look at. The G25 requires a powered usb 2.0 port. If you have your G25 connected to a hub that is not powered it may cause this problem. Likewise, if it is connected to the PC make sure that they usb port you are using is 2.0 and not 1.0. I don't know if this is your issue, but it may be worth looking into. If it is not, at least you have eliminated one more possible cause. I hope this helps.

p.s. sorry I didn't take time to read the rest of forum posts, but I was having issues like this and actually called logitech. It fixed my problem. The key word is powered port. The G25 is a power hog. Also, if you have other game devices make sure they are connected to a powered port. I found that the best solution was to connect all of my gaming devices to a seperate USB 2.0 hub with its own dedicated power supply. This takes the power hit instead of the motherboard.

[SJ_INSTG8R]

Great point Craig Lewis, I of course never even considered this as to me its just "Standard Practice" As I have been doing it so long and would never dream of plugging any input device into a Hub for just those reasons.(Tho I am sorely running short on proper USB ports these days LOL)

[Spaceritual]

Under Device Manager/Universal Serial Bus controlers, my G25 seems to be using a USB root hub. I presume my USB is the 2.0 version but not sure how to tell .

I have a Mesh pc and there are two USB ports on top of the case and four on the back presumably the motherboard ports? ( ASUS A8N-SLI DELUXE ACPI BIOS Revision 1015 )

I am sure when i bought this pc they said all the usb ports were USB 2

So my question is...how do i get this dedicated USB port and not use a hub?

[SJ_INSTG8R]

No cause for alarm SR;) All USB Ports are on Hubs within the Mobo/Dev Man.
We are talking about people using EXTRA USB Hubs(e.g. and extra 4 port hub plugged into an existing USB port on your PC)

Ah , I can relax again then :) Actually with all the hints and tips I have read lately my TDU is running pretty well now , just need Eden to sort the laggy bits and the other glitches , thanks again :)

Samme her. Spend the first manny days trying to get the d... thing to work.
Spend more time adjusting and reading than playing.

But after setting the G25 up as SJ_INSTG8R it is a hole new game.
Allthow I have to go down to 800x600 in the res.
Its not perfetk but it is ok to drive.
I dont think it vil get any better with the sepc. on my pc. I dont know the numbers of rem ecc but it is working hard to keep up.

An other thing. I dont seem to have any wird bugs on my game!!!!

Thanks to SJ_INSTG8R. You are The king of all settings.

Thanks for the compliment INSTG8R. I didn't have anything else to add, because just about everything you said was dead on. Although I do not usually run force feedback (because I play mainly circle track sims and it makes my line smoother not to run it) everything you have said about the G25 is dead on. I and another sim racer I beta test with at ARCA simracing have done some extensive tweaking with the FFB, and the in game settings are the best to go with, rather than the generic settings that Wingman Profiler imposes. Here again, I am only stating what you have already said, but I wanted to back you up because you are dead on. If you use FFB INSTG8R knows what he is talking about.
*** Just a note to the skeptics***
Sometimes you are better off to try things out of the ordinary without argument. Just remember most great innovations were found by accident.

[SJ_INSTG8R]

Thanks for the compliments folks. :respect:
I started my "FFB Quest" when I got my DFP and started playing GTL. Basically I found the FFB in the game VERY muddy and lacked any kind of real road feedback. On top of that the way GTL implemented Understeer the wheel basically went from stiff to completely limp as soon as understeer occured. It drove me nuts so I started digging thru PLR files and learning settings, asking around about Logi FFB settings and this is the culmination of all my research, having tested just about every combo imaginable.

So if anyone wants some kick butt Profiles for GTL, GTR2 or rFactor Im your man as at this point I can give you mine and if you want "a little more here, a little less there" I can do that too.

[matthijsborgdorff]

Hey SJ_INSTG8R, I've already read many of your posts and find them to be very useful.
I have G25 and framedrops but I have now disabled the gameport on my sblive.

This seems to help a lot as far as framerate caused by FFB goes. I still do experience some framedrop with the steering wheel attached but at least it's a lot less than before. In quiet areas, such as Oahu Raceway I dont notice any framedrop at all but in cities the wheel seems to be causing hickups still. Albeit a lot less severe than before.

I have another question though: I am now using your FFB settings that you posted above and I must say it's pretty wild, so stupid that up until now I have always overridden the game's FFB settings! rolleyesa

However, with these settings there is still a lot of margin for adjustment in TDU itself and I was wondering what settings you use ingame?

Can you post your settings here? You might have done it before but this forum is getting so huge that it's quite impossible to find it.

Finally: Is there a point in 900 degrees setting when using full sensitivity ingame?

Thanks in advance!

:salut2:

[SJ_INSTG8R]

Yes mate running the settings at full linearity and Sensitivity allows you "More Travel" as in smaller wheel movements mean smaller inputs in the game. I had intially tryed it at 900 before I had really gotten a handle on the game but found it to be wrong(probably because I hadnt re-calibrated it) and went down to 540 but then decided once I had it all set up right to give 900 another try and well basically now I have no "snap inputs" and I really only have to crank the wheel around alot other than to do a U-Turn(so basically like a real car)I suppose I am in this game to get as much realism out of it as possible and this feels pretty good to me, not too mention the G25 acts like a real wheel in that it does come back to centre so I love cranking it around and letting it slide back in my hands just like you do in your car.
As for my settings here ya go, I may have changed a few key settings(like I have given up trying to drive the bikes with my wheel and have moved a few Dashboard keys around but the key Wheel settings remain the same. If the CP settings are too small to read(Paint.Net shrunk that pic on me its on the previous page in better size)You will notice I have it at 890 degrees so its not "banging the stops" so to speak when it calibrates.

[matthijsborgdorff]

Cool thanks!

Wow, so you have all the bars all the way to the right ingame huh?
You must have enormous arms by now fighting that huge FFB! tonguegre
It is pretty realistic though, so I'll just try to get used to it. Just sucks that right now I'm getting asswooped by everyone coz I'm learning how to drive all over again! Also the sensitivity way to the right makes the car pretty nervous. Think that is realism that I need to get used to? or is it overly sensitive? I too am looking for the most realism and feeling of driving a real car.

Especially those Logitech settings, i.e. losing the centering spring and damper stuff was a huge change, but definately for the better realism-wise.


One more thing btw: do you not use your handbrake, or do you actually use the shift key on the keyboard as your posted pic indicates? I prefer to have that one on my wheel.


Thanks!
:salut2:

[SJ_INSTG8R]

No I dont use the E-brake at all and well technically by "turning it down" to my settings the FFB will SHOULD actually be easier on your arms(the "fake" dampers and springs actually make the wheel overly stiff and "muddy" leaving alot of the subtle FFB effects lost in the "mud") and the wider rotation will be "less twitchy" basically by lowering the Linearity and Sens. sliders to the left you are essentially "Shrinking" the wheels travel and making it react faster. By having everything set to the right the wheel is at "maximum" usage meaning any input you make in the wheel will be DIRECTLY translated to the game rather than "filtered" and "shortened" by the game"(So basically think of it like make the wheels turning radius smaller as you move to the left)this applies to both the Sens and Linearity as the Lin. is the ACTUAL wheels travel/radius and the Sens. is how fast it reacts within that radius. This is why the G25 is such a great wheel because it WILL allow you to have "real world" wheel radius's so it will force you to turn past say 180 degrees to make a 90 degree turn(180 is all fine and dandy in an F1 car but these are Street Cars and well you will NEVER get around a corner with just a "quarter turn" of the wheel.

I dont find the FFB the least bit too heavy and it has a nice small deadzone just like a real car(so like a real car making lane changes involves just a slight movement of the wheel) and the FFB loads up just off centre as you give it any genuine turning input. In fact I TRIED the "wrong way" the other night just for kicks. You wanna talk about HEAVY?! WOW it was like driving the car in Mud in comparison. If it is too strong for you, I will tell you what I tell everyone for ANY game, adjust the FFB WITHIN the game and leave your CP settings alone.
Of course some cars I find are heavier than others(as it rightfully should be if the Dev's did their jobs and IMO they did a pretty good one at that)I love some of the effects they have used ESPECIALLY the hard braking effect that gives you the sensation of G-load by making the wheel "stiffen up" as it were.
Its small touches like that that have made me such an FFB junkie :laugh:

But feel free to ask away Im always happy to "talk shop" when it comes to this stuff and just remember to recalibrate your pedals and wheel within the games settings after making these changes and I also always advise if you leave your wheel plugged and shut down your PC its always a good idea after booting up to do it again within windows as it seems to react MUCH better with an In-Windows re-calibration then the Start-up one.

[MZWiZard]

Hi there!

Excellent explanation of the FFB and how it works. Being a simfanatic mostly racing Live for Speed, I know the importance of a correct FFB and you are spot on. 10sur10

However, I have a slight problem here: My G25 is vibrating heavily sometimes, when the car is standing still. If I grab it firmly, I can make it stop vibrating, but letting it go again could make it start vibrating again, until the car moves.

Otherwise running the exact same, neutral setting for ffb as you.

Kind Regards,

Jesper

[SJ_INSTG8R]

Thats rather an odd reaction in this game(I expect it in GTL and have nicknamed it "The Wobble") as the FFB if left unchecked will cause the wheel to oscillate getting more and more intense. If you post me your settings or perhaps which Profiler Drivers you are running I can see if I can reproduce it.

Im finally getting back into to working again(I have not been well lately with some odd stomach thing) but I am a CNC Machinist and have some big plans for G25 users so keep an Eye on my Sig as you WILL be interested ;)

[Thjalfi]

I have done some benchmarking and although my overall framerate is not as good I can see it breaking down even more when using the G25 with FFB.
I've tested
- steering with keyboard, no wheel connected (although I don't think it makes a difference whether it's connected or not),
- steering with G25 FFB activated, starting game through Logitech Profiler,
- steering with G25 FFB activated, starting game through the normal shortcut,
- steering with G25 FFB deactivated (by deleting regfiles), starting with and without profiler.

I conclude that there's no difference whether you start the game through the profiler or not and that there is a massive decrease in fps when the G25 controls are used regardless if FFB is actually deactivated unless you do so by deleting the registry entries.

I'm still new to the concept of FFB and I mostly drive without it, so I don't have a problem deleting the registry entries to disable it. What bothers me is that now there is a constant centering spring although there shouldn't be any FFB at all. Can someone tell me how to turn that off?

[Thjalfi]

More recent playing suggests that even with the deleted registry entries the decrease in fps when turning or using the pedals of the G25 is there, it just takes longer until it's noticable.

I think TDU just doesn't handle input from gamecontrollers very well which is plain silly because it's supposed to be played with those.

The reason why some people are having issues with this and some not is in my opinion that a drop of framerate from 60-70 to 40-50 isn't such a big deal because the brain can't properly process more than say 30-40 frames per second anyway. The people with lesser performance on the other hand are having a drop from 30-40 fps to maybe 10-20 which is easily noticable or even unplayable.

I hope Atari does something about that with a patch soon.

[zbig77]

I have the same problem with G25 and TDU. The framerate is dropping to unplayable level when the G25 is pluged in. My rig is not really high end anymore and 20fps are already making me happy.
I had to unplug the G25 and am using a gamepad for driving which works to some extend but cannot be compared to driving with a wheel.

I would say its definately TDU problem (No issues in other games) and I hope it will be fixed soon.

[G25-User]

same problem here buddies! :noooo:

i've bought the wheel only for this game because i saw that TDU supports clutch
and H-shifter. before that i had a trustmaster ff racing wheel, which is an awesome
wheel already. now i am selling it after spending 200 euros on the logitech G25.

here are my computer specs:
- Microsoft Windows XP Professional SP2
- Asus A7N8X-E (newest BIOS)
- Athlon XP Mobile @ 2300 MHz
- 2x 512MB Infineon Ram PC3200
- ATI RADEON X850 XT 256MB AGP (with Omega 3.8.330 drivers)

the system was freshly installed 04/30/2007 with all available windows-fixes.
logitech profiler ist not installed. the wheel itself is working perfectly as well
as the shifter and the pedal compartment. BUT it's slowing down the game
after a while as we all know and i am really looking forward that they fix this
problem with the upcoming patch. i am pretty sure i will sell the wheel and
the game if not. :mefiant:

what i tried so far:
- no other usb devices plugged in except the G25
- switched off any effects (force feedback)
- tried it with and without the drivers
- tried different usb ports as well as a usb hub (powered)

i didn't try it with other games yet, but i am pretty sure it will work there.
did anybody noticed that most of us have ATI graphic cards running yet?

any good suggestions for me to try something different to get it to work?

cheers from germany :salut2:

[Thjalfi]

Now that you mention it, it IS strange that everyone that posted their specs had problems with ATI cards and no problems with Nvidia cards. I myself have an x1800xl and problems when turning with the G25.

[SJ_INSTG8R]

2 ATI X1900s and a G25 no issues here at all.

[MZWiZard]

I have a very good idea! mdr1

Go to www.liveforspeed.net and download the "Live for Speed" demo. It fully supports your G25 and it takes you online even in demo mode to race more realistic than TDU. And i suggest you buy that and you'll have hours of breathtaking racing vs. real online racers with no abilities to cheat! :bravo: :bravo:

[G25-User]

@SJ_INSTG8R
it could depend on the drivers and on the ATI model itself, too. i don't know,
but this is not the only forum where i red about this issue and everybody had
an ATI card as far as i remember. what exact vga drivers are you using atm?

@MZWiZard
great idea, but two completely different games. it's as sensless as you would try
to compare need for speed with a formula 1 simulator. do you know what i mean? ;)
i am often just driving/cruising around for hours, without doing any races in TDU
and just enjoying the cars and the nice looking island while listening to my music.
10sur10

@TOPIC
i tried it with the original ATI catalyst drivers tonight (version 8.360) as well
as the newest DNA drivers (version 5.0.7.1) and it didn't help at all. so i had
the most common drivers and alternatives to the original ones installed and
tested. i am 99% sure it's a game-bug. those are the average fps results
i got with all those different drivers (car standing in front of a wall, no big
graphic effects at all so i could get steady and comparable rates, i set the
graphic settings to 1280x1024 and high, nothing else, no vsync etc.):

idle: ~25fps
hitting the gas/clutch in neutral gear: ~17fps
turning the wheel: ~15fps

jez, it's so annoying...

@ALL
it would be great if somebody could try any older ATI vga drivers with TDU!

You are quite right ;) Just wanted to inform you of the ultimate driving simulator for pc, that makes the most of your G25. :salut2:

- I purchased TDU for exactly that reason you mention, cruising. :)

@Topic

I have no slowdowns or stuttering, running on C2D, geforce 8800GTS and G25. After upgrading to Vista 64bit and forceware 158.22 TDU runs very smooth. Perhaps Vista would cure the problem you have? (But of course introduce other annoying things) ;)

Or how about disabling onboard USB and use an add-in card?

[G25-User]

@MZWiZard
cruising on a race track? :laugh: but i will check the game out, thanks! i will try
a usb-card also. i hope it will help but i doubt it. i would like to try some different
graphic cards but i don't have any :( it would be awesome to know if those
problems have anything to do with ATI cards. your system has again nVidia
and you got no problems. it's weird...

vista? well, it costs money of course but i would't install it before the first big
service pack anyway. buying a brand new os is nothing i would ever do. :nono:


edit: okay, tried it on a usb card (pci). guess what? yeah, it still does not work.
i did another benchmark at low quality as well (car standing in front of a wall,
no big graphic effects at all so i could get steady and comparable rates, i set
the graphic settings to the lowest you can get):

idle: ~31fps
hitting the gas/clutch in neutral gear: ~21fps
turning the wheel: ~18fps

during driving on the island it drops even more of course (under 10fps). tdown:

[MZWiZard]

@MZWiZard
cruising on a race track? :laugh: but i will check the game out, thanks!

Ehh... What i meant was I use Live for Speed for serious driving, and TDU just for casual cruising. :) But if you get it, I'll be happy to meet you online; my nick is... guess what... MZWiZard 10sur10

@Topic

Its sad to hear the addon usbcard didnt help. :( How about using another soundcard/disabling sound? Or perhaps try pci latency tool:

http://downloads.guru3d.com/download.php?det=951

Then give your graphics higher priority by setting its latency to 128 or higher and set usb latency lower? :)

[matthijsborgdorff]

Hey guys,

Firstly I never got back to SJ_Instg8r about the force feedback settings. It took me a little while to get used to the settings. But now, I wouldn't have it any other way anymore! I'm talking bout the profiler/control panel settings and about the gamesettings in TDU too. I now see that FFB isn't so heavy at all once you know how to deal with it. Also, setup this way, you get a very realistic car driving experience indeed :) So thanks again mate!

Secondly, again to SJ_Instg8r: You were talking about recalibrating your wheel in joystick everytime before you play. I was wondering what exactly you meant by this. I know what calibrating is ofcourse, but in my control panel there is no button anymore for calibrating. You can click on properties and watch all the meters respond as you turn the wheel, push the pedals and the buttons. You also hear sounds btw. Anyway, is this what you meant by calibrating in windows? I couldn't find a proper calibrate function anywhere in windows. Only this. Oh and btw: I hardly ever do this 'calibrating' before starting game, and I always keep wheel plugged in. I don't think I ever noticed any difference in wheel behaviour ingame though. Can you shed some light maybe?

Finally, about TDU lagging with G25. I used to have the same problem. And that was before I upgraded my processor. With my p4 2.8Ghz it was unplayable with G25 hooked up. Very low framerates. Adjusting graphic settings did not help one bit so I always played with everything on high(4xAA, HDR on, details High, 1280x768). Then I got my new processor (I broke pins off the old one tonguegre ) p4 3.4 Extreme Edition. (working @ 3.825Ghz) and all of a sudden my stuttering was gone. Also, now changing the graphic settings has huge influence on the framerate. Obviously, my x1950Pro is no longer bottlenecked by my processor. I do still get slightly lower framerates when the G25 is attached but now it's no longer really a problem. Still runs 20FPS absolute minimum in worst parts of city on full graphic settings and pretty high resolutions. When I get to quieter parts of the island fps can go up to 60 or even higher. Usually about 40 on the road.

I used to do the standing still and turning wheel test to check for fps drop too. With old processor the fps would drop hugely when turning the wheel. With new processor there is still a framedrop but it is much smaller than before. So, getting a better processor more or less solved the problem for me, it is strange though that many people with better processors than mine still have problems that I no longer have!

lol, I've played TDU more already than the total amount of time spent on some other games that I used to play. Lol, still the patch hasn't arrived.... if they wait a little longer, it will be too late and I will be tired of this game already. Too bad. Especially for all those people playing this at unplayable framerates still! FPS really makes the difference between huge fun and NFAA(no fun at all) when it comes to racing games! I found that out when it stopped stuttering for me :)

btw, also got a new soundcard the other day, Creative X-Fi Fatal1ty Xtreme Gamer Edition. I haven't noticed any performance change in TDU yet. But I have hardly tested so....

sorry for the long story tonguegre

[Somian]

Hi, the game runs well in 1920x1200 and high quality, but if i plug my MS SideWinder Wheel in the PC i have around 2 fps or something, actually i can COUNT the frames rendered by my PC. Now i think, the game is just incompatible with my SideWinder Wheel. Do you think, i should buy a G25 (i wanted to buy it anyway, even if the game works with my old Wheel) or will i encounter the same problem?

[matthijsborgdorff]

Hi,

I think although the problems caused by the MS Sidewinder were similar to the problems caused by many other force feedback wheels including G25,(not for everyone mind you!) there was something specific about the MS Sidewinder. So, I would say there's a good chance you're able to play it fine with G25. Ofcourse there is also a good chance that you will still experience stutters when using G25. There is no sure way to tell. On the bright side: Even if you buy G25 and it doesn't work with TDU you still have a great wheel for other games. And, there's a good chance that the upcoming patch will fix the problems that people are having with their wheels.

I had a problem with my G25 at first but now I don't anymore. and G25 is definately a great investment! Superfun! specialdri

:salut2:

[Dannythemusicman]

I used to have an MS Sidewinder wheel and recently replaced it with a G25 - the result in TDU was still as depressing as ever. Low framerate once the wheel is engaged (turning the car or braking).

I'm simply waiting for the patch, but I must say my receipt is still in side the DVD case. Whilst I like to think I'm a patient guy - Atari better sort this one out as it seems to be one of the most common bugs in TDU next to the corrupt save game feature.

[preved]

Hi,
I have
E6400
7900GT
1Gb 667
Everything works fine with g25, but only one thing i can't understand:
manual gear (H-shifter) does not work with every car (such as Lamborghini, Jaguar, Audi...)
Should it be so, or I'm only one with that ?

The cars that don't have H-shifter irl can't be shifted with it in game either, use the paddles instead.

those have sequential gearchanging, meaning you can only use paddles. So its like that for everybody :)

[G25-User]

you guys would do everybody a favor if you tell us what systems you are playing
TDU with! and yet another nVidia user (preved) with not problems. somebody should
defenitely check out if there is a difference between nVidia and ATI. it should be somebody
which has the G25 + ATI vga and the problem we are talking about. additionally
a friend or whatever who could lend him a nVidia card to check if the assumption is true or not.

*still waiting for the patch*

[matthijsborgdorff]

I suggest we just wait for the patch instead of going out of our way to try and determine causes ourselves. Ofcourse don't let me stop you tonguegre

If patch comes and doesn't fix problems I'll be the first to post my settings and experiences and problems here.

Until that time.

:salut2:

[Dannythemusicman]

Well to clarify things this is my rig:

AMD 3800 X2 (DC)
2 gig RAM
ATI X1800 GTO

and of course... Logitech G25 rolleyesa

I too think at this stage we should wait for the patch and see if Atari have figured things out yet.

[CyberDrunk]

Well, i dont know if the problem is related to the wheel,but...
since i began to play the game with keyboard, my stats in the TDU page were always updating as i play, but since i buyed the logitech G25, the page dont update my stats!!! :mad:

[G25-User]

of course we should wait for the patch. do we have a choice? :laugh:
but i don't mind checking some simple stuff as long as we are waiting,
since every day without TDU is a lost day. mdr1 and who knows that
atari will release the patch in time? it's almost june my friends... ;)

@Dannythemusicman
welcome to the ATI club! :rolleyes:

edit:
In order to give players the high quality of experience they expect,
the Test Drive Unlimited PC patch will be released in mid-June following further
testing to ensure the complete stability of the code.well well, i am not surprised at all. so could anybody try what i wrote in #68 now?

[Mskiba]

hey hey.

I had same issue with..erm...some other weired ferrari wheel..

aaanyway, i turned off the force feedback ingame and it sorted it out :)

[matthijsborgdorff]

Atari better sort this one out as it seems to be one of the most common bugs in TDU next to the corrupt save game feature.


Lol, funny that you called the corrupt savegame bug a feature :laugh:

[G25-User]

aaanyway, i turned off the force feedback ingame and it sorted it out :)that's not helping either. i tried all that before. it's a G25 problem!
whether we wait for the patch or somebody with thit problem should
try different graphic cards, because that's what i think COULD effect it.

[matthijsborgdorff]

Let's say someone with an ATI card has a friend lend him his NVIDIA card and he finds out that the problem disappears and indeed the problem is ATI cards.

Are you gonna get rid of your ATI card then and get an NVIDIA card? I know I'm not. Ofcourse I have AGP so my only NVIDIA alternative would be 7800GS which sucks in comparison to x1950Pro which I have.

So.. my point: are you gonna get a new gfx card if you find out ati is the problem? I'm sure the patch will fix it. Besides, I think I've seen people with NVIDIA cards who have the same problems. Although I can't remember specifically who they were :rolleyes:

[G25-User]

@matthijsborgdorff
yeah, i would. i want to play this game finally! and a 7950GT is faster
than a X1950 Pro in some benchmarks. but i would wait for the official
patch first of course. if it solves my problem: perfect! :bravo:

i am about to put a entirely new computer together anyway, but that is
not gonna happen before the end of july, so i have to make the best of what
i have till then. and in case this problem is due to ATI, it would make my decision
which GFX to buy for my next computer much easier. ;)

[B1gch0pper]

I know 'G25-User' said he tried this without profiler installed and it was the same, but i have been having problems with my G25 since the start and finally sorted them out the other day. I uninstalled the logitech profiler completely from my system, and now it seems to run a LOT better...
I also got rid of any connection problems by cutting out my router (even though all the ports that were supposed to be open, were opened) and pumping my broadband straight into the back of my PC, diasabling ALL firewalls, anti-virus etc (infact disabling everything lol, i only have 18 processes running for the game)
Game runs like a treat now, and i have an X800 GTO and a Soundblaster Live! 5.1, which the readme states this combination has a known problem with the game.
Just trying to help :wink2:

if you uninstalled the profiler does that mean ur not using 900 degrees? tell me more.

[G25-User]

@B1gch0pper
so you had the exact same problems with framerate dropping when turning
the G25? how are your framerates now? you can display the fps ingame by
editing the game shortcut setting into

"[...]\TestDriveUnlimited.exe" -fps

let me know what you got now (average). are the fps still dropping when you
turn the wheel? if you post your results, post your graphic settings as well.

i did try turning everything off before starting the game but it didn't do anything.
put your router back together again and check if anything changes, because i
don't think that did anything at all ;) what drivers do you use right now?

players with high-end graphic cards may have the same problem as we do but
they don't complain, since you don't see any difference between 80 and 60fps.

@Mskiba
i still have 900° without the profiler!

[B1gch0pper]

You can set up the amount of steer you require using the windows 'game controllers' options...
Go into Control Panel, choose game controllers, it should find your wheel, and find calibrate, then set up the amount of steer u require when it asks u to turn your wheel left and right.

Yeah ive had exactly the same problems as this thread encounters (i did post on page 1 saying).
My framerates were...

30-45 sitting still (no wheel turn)
5-10 turning wheel

now im never going below 20 even in the citys, but the thing is the wheel is so much smoother now, its not like im fighting to stay on the road. Even when the FR drops to 20 the game is still much more playable because the wheel is not lagging out as before...

Try it, uninstall profiler, and try it.
As far as im aware it leaves your settings files in the Logitech folder after uninstallation, so if u want to reinstall it after for your other games it will hold your settings...

[G25-User]

i dumped the profiler long time ago. so that's not was caused the problem on my
machine. what i wanted to know if how your framerates are now. take your car
out of the garage, park it in front of a wall or whatever makes the most fps and
then turn the wheel and tell us if there is any less then when you don't touch it.

what drivers are you using with you X800GTO?

[B1gch0pper]

No they do not drop at all, its now the scenery that dictates my framerate, not the wheel, i sit at a constant 40-45 outside citys, and 20-35 inside.

And drivers wise as stated below, the original Catalyst 7.4...

[G25-User]

that sounds good. so you really got rid of the problem. congrats! mdr1

i will keep trying stuff, i hope i can change things, too. i pray for it! :laugh:

i guess TDU is very processor-dependent if you look at our systems:
you have the better cpu (P4 3.2 vs. XP@2.3GHz) and i have the better
gfx (X800GTO vs. X850XT). but you got almost twice as much fps as i do.
what are your game-settings (resolution, detail-setting, etc.)?

[Mskiba]

Ive just uninstalled my profiler and it too is running better, but at a cost.

You see when the profiler is not on PC, you dont get force feedback from game, just the normal Spring to return you to centre. If i hit a car or go into slide there is no feedback through the wheel no more.

Soo, uninstalling works to save fps, but thats because you have turned off FFB.

am I wrong?

[Mskiba]

also now after uninstalling i have no way to alter the amount of FFB (the spring hardness) as changing in TDU how now no effect and cant find an option to change it in windows.

[Mskiba]

can anyone help me out? TDU does not use the full 900 degrees of my g25.

The way i test : look at my car from outside and inside and observer the wheel / steering wheel moverment. and the full lock maxes out while my g25 still has around 100 degrees left in its turn.

LFS uses the full 900 degrees but cant get TDU to do the same. Ive tried messing with the 3 steering options in tdu but no joy.

how do i solve this?

[dtabod]

Its called wheel linearity or steering rate MK something that the in game does not have a direct function on. just mess with sensitivity and the other slider i forget what its called but its right under it. it works kinda like steering rate (in game settings)

[Mskiba]

just mess with sensitivity and the other slider i forget what its called but its right under it.

Ive tried messing with the 3 steering options in tdu but no joy.

:noooo: :noooo:

[Scorpius_SWE]

:noooo: :noooo:
You have to change to 900 in the control panel-game something.
Then both sensitivity and linearity far to the right will do it

[Mskiba]

in control pannel i got it set to 886 (cant get 890 like rest of u guys, how u do that? lol)

still TDU does not use the last 120 degrees or so from my wheel :(

[matthijsborgdorff]

hehe, ya that slider is a pain tonguegre I just slide until I have a number that is a multitude of 5. Then I use the keyboard to get it to 890. The keyboard will take steps of 5 degrees exactly when pushed.

As for the game not using all the degrees, I have it set to 890 but I have never actuallly measured the degrees tdu uses. Haven't noticed it being smaller than in other games either. Could be this IS so though. I guess I just wouldn't notice if it were. Anyway, still enough rotation left! Right? tonguegre

[Cube623]

hehe, ya that slider is a pain tonguegre I just slide until I have a number that is a multitude of 5. Then I use the keyboard to get it to 890. The keyboard will take steps of 5 degrees exactly when pushed.
thanks for that tip mdr1 . I was having to set my degrees to an odd number close to 890. Thanks again!

Cube623.

[Anarchi]

I just got my G25 and have no performance problems at all, even when using hard force feedback.


* I have no other gamepads/joysticks attached to the PC
* I am not using G25 Profiles.

Specs are:

Intel Core2Duo E6300
Asus P5B Deluxe Mainboard
2GB PC667 Memory
GeForce 7900GS
WinXP SP2 with 9.0c + various 9.0c updates
G25 drivers tested ok: The ones that came on the CD and the newest once from logitech (although the HID device driver is the same revision)

[Mskiba]

reason being is that you have a monster CPU that could break a FBI code quicker than you can spot a bug in TDU and the fact that you dont have the profiler loaded means your computer dosnt have to calculate any FFB. So its just the same as using a non forcefeedback steering wheel.

[matthijsborgdorff]

Actually you still get FFB when not starting up profiler before driving. I never run the profiler. I only have it installed and used it to set the correct FFB settings once(check this thread how to). Then I just leave it. And play without it. There's no difference in playing without or with profiler, as long as you have it installed and set the settings correct.

As for you not having problems, Your PC is very new so it would have less trouble coping with the badly coded ffb than older pc's would. It's very possible though, that were you to measure your framerates, then unhook the ffb wheel, then measure framerates again, that you will see a difference, game does run slower with ffb wheel attached. It does for me, still runs fine though. Runs better without wheel attached. This hopefully should get fixed in the patch.

Perhaps you will hardly notice the difference because it's already running so sweet on your pc. You can always try the stand still and turn wheel test. See if your framerate drops when you turn the wheel even though standing still and not having the wheel in sight.

My advice to you is, just play TDU and don't worry about it. Since you have no problems, don't try to fix them! Great that it runs good on your pc! Congratulations! Have lotsa fun!

:salut2:

[Mskiba]

this has been covered over and over again.

First of all, when i say run without profiler, i mean with profiler uninstalled. Just exiting profiler has no effect as your computer still calculates FFB. Its just as good as having it running in background. Rememver that a slightest program in the background which uses the slightest cpu will have majour effect on TDU as TDU is so CPU intensive. (profiler, msn etc..)

You dont get force feedback without the profiler, you get force, no feedback. (spring only).

running profiler (thats, having it installed on ur pc) and having feedback WILL result in less fps. Its just on faster PC's its harder to spot.

No point him doing tests as over 10 people with different pc's have done same test with same results. Not sure why this subject is still being debated.

[Thjalfi]

I think it's still debatable if it's really the FFB information that's causing the fps drop or if it's any analog input at all and having an analog wheel or gamepad these days just coincides with having some sort of FFB.

I for example did the thing with removing the registry entries which meant no FFB at all except the standard centering spring (which is Removed btw, I'd rather have no force at all) and I still got the fps drop when turning the wheel. Another reason I think it's not just FFB is that there's also an fps drop when just stepping on the pedals, I tried that out with the clutch when standing completely still and facing a wall so I could be certain there should be no FFB involved.

please dont use stars to bypass the language filter...

What stars to "bypass" the language filter? I wrote a word that was inappropriate and just 4 stars appeared which was fine by me. How is that "bypassing the language filter"?

Even with registry hack it will still calculate FFB just not pass it down to the wheel.

Pressing pedals will also slow you down as that will effect the feedback in your wheel. Thus breaking or Accelerating effects how your steering feels which leads to ffb calculations.

[Boyracer243]

Please help i have been playing TDU for bout 2 days i have an alfa romaoe (escuse the spelling) and i put my settings on manual coz thats how i like to drive any way to the piont i can drive the car on manual and it works fine but i have recently bought a masirati and the gear change wont work untill i put it bk on auto but if i change me car bk to the alfa it works fine agen. i have reset the controls but still no luck plzzzzzzzzzz help. either leave a post or email me petercollins@blueyonder.co.uk

[Mskiba]

manual H shift only works with cars that dont have a paddle shift in real life.

[Boyracer243]

what do mean it only works with car that you dont have to paddle shift coz it works with my alfa but not my masirati

[LabaLaba]

what do mean it only works with car that you dont have to paddle shift coz it works with my alfa but not my masirati
Alfa has a H shifter and a clutch in real life, so you can use the H shifter.
The Maserati has paddles, so you have to use them also on your wheel. You can't use H shifter with your Maserati.

[Jabe-BRD-]

is there any way that i can use both modes of shifter? so instead of padles i could use shifter.

Hi
Does the Patch fix the problem of the dropped down fps or is it still there because I maybe want to buy a G25 and it would be very stupid it if doesn't work in TDU with my ATI-card --> Signature. Hope there's still someone interested in this quite old thread. :)

Your card is not quite capable of running TDU in high fps anyway. Don't know what U get from it now, but U have to count at least 20-25% drop of frame rate when using G25, specially when U have single core CPU. U wont see the drop in about first 10 minutes of playing, but after that it becomes rather significant and annoying.
TDU patch did nothing about it, but there is an updated driver from Logitech, u can download it at their web site, with huge improvements on FFB effects and, so they say, on performance level. I can't confirm it from my experience, since I got the new rig at the same time the new Logitech driver came out, so the performance is boosted anyway.

is there any way that i can use both modes of shifter? so instead of padles i could use shifter.
In theory, there is, but only if U change your controls every time U swap H-gear box car with the sequential one. U only have to remap 1st and 2nd gear, as these are interfering with 'gear up' and 'gear down' commands, and to tick/untick H-gear button in control options menu.

[W8Racer]

I wouldn't say that my card hasn't enough power for TDU. I play it with 1024x768, 4xAA, 16xAF, no VSYNC and in cockpit there are at least 20 fps outside cities and in the bumper view I think circa 25-35 fps at least. In cities well without my Saitek R440 there are almost no lags at all but with it fps are 15-20 fps and you really have a problem to drive normal. I think for my system TDU runs very good because I wondered if I should actually buy it in August '07 because all of the discussions about the performance problems in this forum but as already mentioned it runs quite good. Would you advise me to buy it for TDU, GTR2, GTR, rFactor and GT Legends or doesn't it make sense so that I should stay at my R440? Did you have any problems with your G25 at all because I've read some tests where they said the gearbox is not as well made as the wheel and the pedals are?

W8
Yes, I was talking about fps U have right now. It's not high enough 'cause U'll find your reduced fps (when U plug-in G25) pretty unplayable. With my old rig (Athlon64 3000+, Gforce6600GT, 1GBRAM)I had similar fps as you with a gamepad, but it dropped to 10-15-20fps after 10 minutes playing with G25. I think it's highly dependable on your CPU power, not GPU. G25 eats CPU resources, add to that hungry TDU and what U got is laaaaag.
I've experienced similar fps drop with GTR2, not as drastic as in TDU, but rFactor and LiveForSpeed runs like a dream.
G25s capacity can be fully employed in 100% simulation games like rFactor, LiveForSpeed, GTR2 (no driving aids of course) and Race07 (my recommendation). Gear stick is 2 class below the wheel and pedals indeed. I would pay some good money to have some decent gear box plugged instead the original one. I quit using H mode, as it's very noisy and seems too fragile...

[W8Racer]

But can you compare an Athlon64 3000+ with an Intel P4 3,4Ghz with HTT? As far as I know HTT is a technology where you only have a phyiscal single core. But the technology makes the OS thinking there are two cores because it add a virtual core. Correct me I don't know that better :) . Because of that I should maybe have better chances with my CPU? And if you would have to decide between rFactor and Race07 you would buy Race07 you said? Why? And thank you for your answers so far! :)

I didn't say these two CPUs are similar, I'm only giving a reference to something I'm familiar with. Don't know anything about HTT technology, but I'd always give an advantage to something physical over 'virtual' :) ok kiddin' really don't know anything about it.
I recommended race'07 'cause i love it, as an improved version of GTR2. I played only free version of rFactor and I liked it too, till I tried Race. Both are excellent but in short, Race has everything lifted to the next level. G25 is an excellent choice for either, so it's up to your personal taste.

[zbig77]

Hello again after 10 months !

I was following this thread for quite a while, as I also have massive frame rate drops in TDU when G25 is plugged in.

I was hoping that the patch will solve it but I have noticed no change at all.
I was also hoping that by now (almost a year) we can get some feedback from game developer / support on this issue. There was one post in this thread from him, but then silence. magicfr any infos from you on this issue ?

Well I end now using gamepad playing this game and my G25 is gathering dust. Thats simply not right and it is clearly a game issue.

Any news on this topic from other users ?

Is this forum the official way of giving feedback / sending support questions (like the G25 problem) or is there other way to do it ?

===

Im running:

Athlon XP 3200+; 2.5 GB RAM; X1950Pro 512MB;

[kalniel]

Is this forum the official way of giving feedback / sending support questions (like the G25 problem) or is there other way to do it ?

No the forums are purely user to user support. Official support contact details are in the back of your manual and they're the people to raise this with.

I think your problems are almost certainly the result of using FF with that processor - TDU is CPU intensive, and FF is also fairly CPU intensive, but your AMD chip can't cope with two intensive processes at once and this causes the problem.

[zbig77]

Thank you for the reply kalniel.

I could live without FF. I would at least like to use the wheel and pedals for steering. If your statement is correct turning off FF should help but how to do it ?

So far I have tried:
1. Turning all FF sliders in properties to 0% (both G25 driver as in game) => no joy
2. Unplugging the power supply of g25 to disable FF => no joy
3. Closing the profiler before launching the game => no joy

To be tested:
4. Uninstalling the profiler
5. ??? (input welcome)

Only thing that helps is unplugging the g25 totally (thats not the goal).

P.S. I get your point about my CPU, but how comes that it is working nicely for first few minutes and then decreases ? Looks more like a memory leak / bad programming, because my CPU is not getting worse and worse with time :rolleyes:

[kalniel]

Good question. I don't know and I've not looked into the processes, but you should be able to see a memory leak if you look at the task manager during the game being run. CPU load can increase over time if the game tracks more things, but it's also possible that just by starting one more process part way through (like the game auto-recording some stats) it bumps a vital thread out of completion within the normal CPU cycle.

I can't answer the FF turn off question, as I don't have a G25. I'm sure the answer is here somewhere though (or someone else will be able to say).

[DessyRascal]

dont remove the profiler the wheel wont work at all :)

open the profiler goto options > global device settings. disable the top slider and ingame controls > options tab, disable ff settings.

you cant completey stop ff with the g25 as the motors work to power the steering etc of the unit itself.

if your prepared to do it you can alter the profilers ini files, are try see it that total disables the ffb the file looks something like this

you can also disable the profiler, do not have the profiler activated (i.e. i do not launch any game through the profiler software) when playing any game

[zstef]

But altering of INI files would be the same as if he unchecked the "Enable Force Feedback" checkbox in Game Controllers' properties, wouldn't it?

You can turn the FF off by disconnecting the wheel while in game and then reconnecting it. There won't be any FF, and probably no lag. If lag is really FF related.

[zbig77]

I did a number of benchmarks.
With profiler installed, FF turned on and off, G25 connected and not etc.

The result put short is that wherever any input from G25 comes fps drop comes. It doesnt matter if FF is turned on or off or profiler is running
I also had the impression that its not only fps drop but some kind of laag (delay between wheel input and in game reaction), which is actually more distracting then the fps drop IMHO.

Looks like the only solution for users with this problem is to get more powerfull rig or continue to play with gamepad.

Im going back to some more serious simulations.
I may take another look at TDU someday when Ill get new rig.

Till then,

Zbig out.

[kalniel]

:(

Thanks for reporting that - more information is always good.

Out of interest, what's your USB poll rate?

[zbig77]

Out of interest, what's your USB poll rate?

I have never changed it so I guess its default 125Hz (unless one of my usb devices changed it - maybe TrackIR...) Ill check it today when I will get back home.

I have quite a number of USB stuff plugged :
- Keyboard
- Mouse
- Logitech G25
- TrackIR
- Saitek X52
- Wingman 3d (modified as rudder pedals for flight simming)
- Gamepad (temporarly for TDU)

[DessyRascal]

are you using a usb hub thing, its best if you can have everything connected to the computer and not running through a expansion hub.

[kalniel]

Heh that's a fair amount!

It might be worth sticking the G25 on it's own controller and have a go playing with different polling rates.

It might also be worth removing other devices when trying TDU.

Yes, I am just throwing ideas out there :nuts:

Hi guys, expecting my G25 arriving first thing in the morning via citylink.

Now my rig is a

AMD x2 4600 @ 2.4GHZ
3GB DDR400
250GB HD SATA2
HIS X1950 pro 512MB GDDR3 pci-e
Creative X-Fi Audio pci 7.1
Vista Ultimate SP1 rc1 public beta


Now I run TDU right now about 30FPS normally and only drops when in external view, I blast through cities no problem with a Formula Force RX wheel with the profiler running, so I hope to give you guys a extensive review on what I find with the G25, as I shall attempt to run TDU without installing the profiler, just install wheel and go, and then after a while I shall install the profiler and run the setup on the Logitech website as I like latest drivers, and use the configuration posted in the image previously in this thread.

I have reviewed this thread and it seems the G25's FBB really slams on cpu power, given most users have enough ram, now I run TDU at 1680 by 1050 all on high no HDR, with only AVG in the background, and my router permitting the TDU program, I plan on using this to run the G25.

Wish me luck.

[Weally]

Hi guys,

Thought I'd share my experience.

I'm experiencing the same problem and it never happened until I changed to ATI.

My Specs are:

ASRock P4i65g
P4 3.2 HT @ 3.5
2gig DDR400
Sapphire X1950 Pro 512mb AGP
2xHHD
Creative X-Fi Extreme Music sound card

I first bought this game and ran it on exactly the same setup above but with a XFX 6800XT 256mb AGP. I ran the game on low and, while I wasn't getting great FPS, it was smooth and consistant with my G25. I cannot recall losing any FPS while using my 6800.

I decided to upgrade my graphics as I'm in no hurry to splash out on a pci-e system so I purchased a Sapphire X1950 512mb AGP after reading many reviews on how good this card is compared to it's price.

I was impressed by the improvement in other games and I can't argue about TDU as I now play all high plus 4XAA no HDR (can in places but prefer smoother gameplay).

I now lose between 5 -15 FPS depending on how much I steer but this never happened with my 6800XT so I 100% agree with the people who think it's an issue with ATI owners.

I have changed my USB polling rate and saw no change. I've formatted several times over the past few months and everything runs smooth. I've even used driver cleaner and tested several graphics drivers but nothing works.

There is a conflict which is localised to ATI cards (possibly not all manufactures) and this game as I play LFS and tried Rfactor with no FPS drop.

If any of you have an ATI card and an old Nivida card, maybe you could be so kind to test this theory so we can get to the bottom of this once and for all.

[ZeroMinded]

Weally,

especially for you, i made an account for this forum,

the problem is very easy to solve...
if you switch from Nvidia to Ati (or backwards)
your windows settings get all messed up!

the best thing you can do is reinstall Windows.

its really !@#$%&.... but i bet it works.

if not..
try OMEGA drivers... ( http://www.omegadrivers.net/ )

i really hope you can sort this out,
im goin for the G25 too, and i got this spec's

AMD Athlon64 3800+
ATI HD2600XT
Chipset: ATI RS400 (yes i own a barebone)
--
WINXP PRO SP2

so i hope it works all just fine for me :respect:

[kalniel]

I don't have a g25, but I can confirm swapping from nvidia to ati *can* cause problems. A fresh windows install is always best, but you should also be ok as long as you thoroughly cleanout old drivers - including AGP drivers. Then build up again with fresh AGP drivers first, then graphics card ones.

I went from AGP nVidia to PCI-E ATI on the same windows install without a problem.

[Weally]

Thanks for the replies guys and sorry if I didn't make it clear enough. I've already formatted several times and started XP from a fresh install. I even did it methodically, installing my hardware piece by piece and ensuring there's no conflicts anywhere.

I even ran driver cleaner before a fresh install of the gcard just incase windows tried to install any possible ati drivers stored within its pre-supplied driver folder.

Every other game runs fine without any FPS drop so I can rule out the possibility of a driver conflict due to left over driver files which may still be lingering after a different gcard install.

[Lizard_Of_Bodom]

I appreciate it, ideas are always welcome.

I will give it a go and write back here, but my initial motivation is gone :(

Zbig, dunno if you have solved the issues you had or not, but just to give you a little support - I have G25 and have never-ever experienced any problems with fps drop-down on my old rig. I used to have XP3200+ like you (1 GB + 7600GT) and fps was never dependant on having G25 connected or not. Wingman profiler was off. It was einter on pre- and after-patch game So dont blame your old PC components as they are for sure enough OK not to interfere with G25.
good luck! :salut2:

[NigelJoseph]

Alright So Ive Followed The Entire Thread Start To Finnish And Im Having The Same Issues...Maybe Tommorrow Night Ill Get My Friend To Come Over With His 8800GT And Swap My ATI Card Out. There Seems To Be A Random Processor Spike However Because The Game Runs Completely Fine Then Suddenly Slows Down And Then The Processor Spikes And It Speeds Up Again Shortly After Only To Do It Again... Any Ideas Mates?

[mazertmj]

You know, I've been reading this thread this evening and just wanted to throw in some input that no one has really mentioned.

If you take a computer that is running games at a high frame rate, and drop in a second graphics card without properly upgrading the power supply,
you experience frame rate loss and other side effects.

Could it be that the power requirements of the G25 are causing issues for you guys?

Anyway, my G25 will be here tomorrow. I can't wait. I'll update whether I have issues or not.

p.s. - Yes I know this thread is old mdr1

[Colster]

It does seem to affect ATI cards particularly. When I first started playing TDU I had an X1950 Pro 512MB, this could run everything on high @1440x900, with 4AA, no HDR (AMD X2 3800, 1GB DDR RAM) with a slight but noticeable drop in fps while in the city.

When I bought my G25, the fps dropped making the game perfectly playable still but the city became a bit of a no no.

The biggest problem for me was that after a while the FFB seemed to start having a greater effect on the fps and would drive it into single figures even when you were out of the city. So sharp cornering on a bumpy road would always lead to a crash.

If I stayed in game but unplugged and replugged the wheel, then it would be fine but I would lose all feeling through the wheel (no centreing or FFB). The other option would be to ALT+TAB out of the game, wait for the HDD to stop churning then go back into the game, this would work for a bit but the problem would return after a while. The best fix was to quit and restart the game.

I then changed to an nVidia 9600GT 512MB and voila no more drastic drops in fps after playing for a while when the wheel was getting lots of FFB. I can run this card with forced higher AA and drive my fps down to what I used to get with the ATI but it stays like that now and doesn't drop over time.

It does seem like there are 2 problems being experienced here though:

Where the wheel has an effect on the fps straight away that is noticeable and disruptive - Would suggest that the system is a bit underpowered as a whole and the added load of the G25 is just too much.

When the game runs fine to start with but the fps starts to drop after a while when FFB is being sent to the wheel - Do you have an ATI card? Consider switching.

I can't say that this is a fix for everyone but it does seem like the bulk of the people having problems seem to be ATI users (usually x1950) and I can definitely say switching to an nVidia fixed it for me.

Ive Read Through This A Few Time, I Have Yet To Test Certain Things But I Bought An 8800GTS Thinking It Was My ATI Card...First Time i Played TDU With It Thr Game Ran Beautifully For A Few Hours Then I Exited...A Week Later I Went Back To It And Its Completely Rubbish. Any Help At All With This Would Be Great Thanks.

Hi guys,I wanted to say that my only problem with the G25 is that the FFB doesn't work...this only happens on TDU and even if I set the force strenght to max it doesn't work either. Someone know how to help me? Thanks.:atari:
