I re-installed my drivers back to the CD that came with the G25, and the FF is back. But so is the problem. T3hReaper: I tried that, in each one of my USB ports. No result. NitroBlueUK: I'll try to find that to see if it will help, thanks for the tip. teddyBBK: I'll call them if all else fails, but I usually don't like to go through tech support.

I have Windows XP. Would the Calibration Clearance Program still work?

The new patch appears to have 'fixed' the problem by disabling the FF entirely. It no longer works in any game. I don't know why, but I'll keep looking into it.

I updated the driver to 5.02.166, and that seems to have solved the problem. I'll play around with it for a bit and see if its really fixed.

I did re-install the driver, once before and once after I read your suggestion. Didn't do anything. Those were all 5.0.182 drivers. I'm going to see if I can find a more up to date driver.

Hey guys, I've been having this problem for a while now, and after looking around online for some time, I decided to join a forum and start a thread. When I load Test Drive: Unlimited (PC DVD Version) with the G25 wheel plugged in, it runs fine in the menu. When I enter the game itself it runs fine during the animation of your house. It isn't until I take a car out that the problems begin. Once I'm in the car, I can sit in the driveway just fine with no problems. But as soon as I turn the wheel (Ragardless of rather or not the car is in motion), the frame rate drops drastically, the more violently I turn the wheel, the more the frame rate drops. I've seen it hit as low as 2 fps when I'm going fast and turn the wheel suddenly. If I load the game with the G25 unplugged and drive around using keyboard controls, everything runs fine. Hardware Specs: Operating System: Windows XP Professional (SP2) Processor: Intel Celeron D 3.46 Ghz (Single Core) Memory: 2 GB of Corsair DDR1 400 Mhz Graphics Card: HIS Radeon HD 3850 Turbo with IceQ3 cooler (AGP x8) w/ 512 MB Memory Before I upgraded my computer to the Radeon, the game worked just fine, so I assume that in some way the G25 is interacting badly with the Radeon. In any other racing sim the wheel works fine, so this problem is only with TDU. I've tried many of the fixes suggested online (Changing the AA settings, changing the Catalyst AI to advanced, etc.) and none of them have worked. My previous system was an Nvidia 6800 XT and 1 GB of Ultra DDR1 RAM, so it's not that my current system is less powerful. The game ran fine on the last hardware. Any help is appreciated :)
