Presumably you’ve tried adjusting the sensitivity settings on the wheel itself (see the wheel’s instructions) - not within the game. Mine works fine without adjustment on FH3 but on FM7 I have to use sensivity level 4.
Some of my friends have the same wheel and whilst it was fun for a while, we’ve all stopped using it and prefer the controller or elite controller.
If you want to read other people’s comments there is a separate thread:
