I thought wheel support was game dependent on the consoles (not system wide like windows)
the DFGT is supported in this game on windows along with more or less every wheel out there including really old ones llike the microsoft sidewinder wheel (great wheel btw) and the original logitech force also thrustmaster and fanatec wheels. It also has a custom wheel config and custom controller config
No, in this case it is also system wide - Logitech stopped making wheels, and the new consoles require the USB connection to be secured. Logitech stopped making wheels before that requirement, and currently there is no solution. So basically there's a certain cut-off date before which none of the then produced wheels work with the next-gen consoles.
So all modern Thrustmaster and Fanatec wheels work, but none of the Logitech wheels made it to next-gen. And as they have been the most popular especially among PS3 gamers (Xbox 360 was relatively closed off in terms of options in comparison, because they had some restrictions in place already).
Really look forward to trying this in Project Cars on PC now!
Also just tried 3D on this for the first time, and that's actually really nice too. Makes judging the corners much easier, and unlike in GT6, I can keep it at 1080p60 no problem.
