I'm having the same issue on PC with my Logitech G Pro wheel. Partial FFB, can feel curbs and ground effects, but no wheel weight, it feels terrible. My wheel works fine on other games. Please fix....
Ideas
Turns out, it might be AMS2 that might be overwriting registry settings for the Logitech Pro wheel that screws up its functionality in the F1 games. Reinstalling all the wheel software should fix it! This is only a hunch!
