Personal preference, thats whats good about vorpx – you might need a ready profile to have 3d depth effect in your game pre-made for you if you cant figure out how to do it, but after that you can adjust it the way you like.
My personal preference for most games including kingdome come are immersive screen and ambient background with no head tracking and switching to z3d in most modern games for performance reasons. That worked for me in kingdom come too.
