TrackIR 4pro is stuttering my IL-2 Help!!

[l88bastard]

Ok so I am a relatively new crackhead to the IL-2 series.

I discovered it about a month ago and at first I was playing it with my wired xbox 360 joystick and then I went all out and picked up the CH products Fighterstick, throttle, peddals and trackIR 4 pro.

Well the game runs as smooth as silk until I try to use my track ir. When I use TrackIR, It stutters and lags when I turn my head to look and it is incredibly annoying. I have searched all over online, but I cannot find any definitive solution.

Can anybody help me? Like I said, the game runs perfectly smooth as silk if I disable trackIR!!

I am running a quad core 3.6ghz, 4 gig-o-memory, two 8800ultras in sli, and vista 64 ultimate, so I know I have plenty of power here...whats the deal!!
