I have the AF V3 steering wheel and when i load up ACC i will 50/50 get no FFB at all.
I use cloud tuning and get the notification that it has found a profile for my car/track combination yet there is nothing there, no FFB, no resistance etc.
Not sure if its due to some conflict or issue with SC.
Every so often it does work and feels great, but as i said, half the time there is nothing.
