dirt 3 pc logitech wheel unresponsive

Answer 1

try updating your drivers and patching your game. i've had this before where i've updated my g27 drivers and forgotten to restart the pc before launching the game.

make sure it's all plugged in and has finished it's startup calibration where the wheel rotates a couple of times on it's own before launching the game.

 

EDIT - also, run the logitech calibration/testing software with your drivers to check there is actually input sensed by your pc. if not, then it's a call/email to logitech support.
