I am having a difficult time trying to recenter my image in game (VR mode: Oculus Rift CV1) . I have tried Ctrl+space Ctrl+C and even F12 (found these options in the Steam forum) with no change . I have also tried adjusting with seat up/down/forward/back there is no left/right adjustment so at this point its back to Assetto Corsa.
Backspace is the new key for centering VR You can also map it to any key or button on your wheel in 'Controls'
