Did you by any chance disable the X-Box controller override in the vorpX menu in games where it is enabled? Some other user did that recently and expeirenced something similar afterwards.
In case you did that: some games do not allow a gamepad and the mouse (which vorpX needs for head trackings to be used together. Hence the gamepad is overriden in such games and handled via an internal gamepad>mouse emulation.
Only Direct VR games allow native gamepad use in such a case. If Direct VR is not active or not available, there is no way to play games that have this issue without the vorpX gamepad override if you want to use your gamepad.
