No issues with head tracking, it’s mouse based so there’s not much that can go wrong, but the latest vorpX has a bug that leads to glitchy graphics in the game (and a handful other DX9 games), so you might want to wait a bit anyway.
I don’t mind experimenting. Are there any suggestions you can give me on how to get the mouse based headtracking working? Maybe an in game setting? Or resetting the game back to default? What’s the usual reason mouse based head tracking fails?
As far as vorpX is concerned either head tracking being switched off or the head tracking sensitivity dialed down to 0.0. Game wise mouse input might be turned off.
SOLVED: If anyone else has this problem, the in game setting for mouse sensitivity is set to Low by default. This results in body tracking, but no headtracking. I raised it to High and headtracking returned.
