I tied the demo and it looks ok but the game is undrivable with my G25, this happens with all console conversions grid,tocca ect. There seems to be some lag or dead zone that carn't be removed.
I'll stick to sim racing it's much easier.
did you get past the first lap and race ?
I use a G25 and it works perfectly, maybe you just need to put more into learning how the game works and tuning the wheel in the options.. once you have it sussed the games fantastic with it !
