I'm using a Logitech Driving Force GT steering wheel and it is working actually really great with the normal version of the game. I'm using the G29 profile and nearly all the buttons are working correctly (only thing I noticed that isn't working is opening the map but that really doesn't hurt during gameplay) and the force feedback is working great as well.
I just tried the PTS version and now the steering wheel keeps on turning all the way to the right. I can, with a lot of power, turn it back but it keeps turning to the right. The wheels actually stay in sync with the steering wheel and are also turned completely to the right. Tried different underground but this keeps happening on every surface.
