I just saw a Paradise Decay video about God Of War in vorpX, and he explained that he disabled head tracking (=mouse) in vorpX settings to get the DualSense controller to work.
I expected that the screen will be locked to his vision, but he still could move his head in front of the Immersive Screen.
That tells me (contrary to my beliefs) that mouse-based headtracking is only used inside the game, but not for the looking around in front of the Immersive Screen (can’t word it better, sorry).
If this is true: where is this setting located in the in-game menu? I remember trying to disable mouse in the past for playing with gamepad, but that locked the screen to my head!
