When using Vorpx, I can access in-game menu’s but player character doesn’t move and no buttons are responsive.
I (T)ried all xbox override options – None, Partial, Full – and ch(A)nging controller to KB/Mouse, Gamepad, Auto, Off etc. I also tried removing headtracking and changing other settings and nothing, unfortunately.
When the override is enabled in a profile then usually because – as you suggested yourself – to allow mouse based head tracking in games that are unable to handle simultaneous gamepad and mouse input. That’s the point of the built-in gamepad to kb/mouse wrapper. I.e. that’s a feature not something you would want to disable.
