Oculus user here. Some issues I've noticed:
1) Menus sometimes refuse to close
2) Tank aiming sight has no tracking, moving your head does not move or rotate the view, thus nausea.
3) The Z key's distortion is also nauseous in VR
4) Scale is off in some areas, for example tanks feel smaller than real ones, and when joining a carrier's tower, the room (carrier bridge) is absolutely tiny (steel door the size of my monitor).
5) Accessing the controls menu in VR causes heavy FPS drops
