I have a Manta Air Wheel MM62 steering wheel and when I start the RaceRoom game (in a VR mode - Oculus Roft), the steering wheel does not vibrate. The "Force Feedback" option also cannot be activated. Just to clarify - the steering wheel vibrates in a non VR mode.
your going to have to give way more details ; but first thing first , check that your not running the steam controller thing ; its in settings Andi
