If you want to use your VR controllers, you can switch them to gamepad mode instead of mouse/keyboard. Unless this is one of the games that dislike mouse (emulated for head tracking by vorpX) and gamepad to be used at the same time, that’s easier than re-mapping the controllers.
Doesn’t work for all games though. If a game can’t handle mouse and gamepad input at the same time, you will have to use VR controllers in mouse/keyboard mode.
