Not sure what you are talking about. AH doesnt have a "head-tracker" system. It can however use any of the head-tracker systems out there.....trackIR and such.
It has a mode for when you are using the keypad/hatswitch to use "snap views", "pan views", and "instant views". Hitting F7, F8, and F9 for the views.
Looking from front to left....
Snap views shows a quick transition ..
Pan views shows a smooth transition....like turning your head.
Instant view replaces the front view with the left view.
Head tracking does take some work to get use to. Adjusting the curve for the view movement vs your head movement could take weeks (I have a bunch of player profiles for TrackIR on my help site). Once you have it adjusted then there is just getting use to the new play. I have VR and still have issues with tracking planes, too much use of the hatswitches Im guessing.
