Here is a quick video I just made to illustrate the stabilising effect on your viewpoint position that using TrackIR produces. I locked-off the tracking sensors to produce a steady centred view (so not mounted on my head) then showed "g-effect" viewpoint movement in pitch and yaw at different speeds in normal space and then in supercruise, illustrating the difference between having TrackIR enabled and disabled.
It seems to me you have found a way to prevent the dashboard/cockpit from moving at all. That's what I want, though it would suffice if the instruments stayed on screen all the time.
Can this be done on an xbox without buying head-tracking or VR hardware?
