For the profile, I have 720 degree of rotation, and 105% "Overall Effects Str". All the other stuff is at 0. This is pretty much from the manual. In the game, I have 40% ffb strength with 720 degree settings and wheel comp at 1 (although I played around with this to 0 and in between to see if there was a difference). I'll try to take a video and post it on youtube with a link tomorrow. It seems that the wheel just tugs harshly back and forth about 3-4 degrees around the "straight" aligned steering.

Yes. I have the latest driver installed from the Logitech website (5.08). I already have read through the online manual for things regarded the DFGT. I'm pretty confused, and beginning to think it is a hardware problem.

I bought a DFGT (today actually). I tried playing LFS with it. It seems that when I try to go straight the FFB will oscillate the wheel into turning slightly left and right, constantly switching. It's incredibly annoying, and is making LFS unplayable. Any ideas on how to fix this problem?
