Hello,
I setup the pedals in Settings, and they are recognized.
All 3 pedals seem to be working.
But when I start game in pit and set into 1. gear and press throttle/break/clutch nothing happens.
I managed to fix the problem myself.
For others:
1. Remember to set max values for throttle/break/clutch
2. Remember to set auto clutch to On, if you are not used to using clutch.
