Well, the game is awesome, no doubt. But TrackIR, while supported, has issues. First off, the range, or angle, of view is sverely limited. I'm not sure if it can be changed, if someonw knows, cheers.
Secondly, the roll is inverted (tilt my head left, it turns right in-game) I have looked through the NkPro settings, but nothing regarding TrackIR, and I have inverted and verted the Roll in the TrackIR settings... No change.
