I was not sure where this should go, I have been having issues with TrackIR working in the P-51, I look left or right and it stops at about the 7 and 4 o'clock position and the movement seems off all around, I at first thought this was on my end but after flying the P-51 I tried flying a MIG-21 instead and the TrackIR stopped moving all together, or so I thought, the software for TrackIR shows it moving just fine but in DCS it is not, twice I have used the P-51 with same bad results and then the MIG-21 and the head movement stopped, but restarting DCS fixed it but only in the MIG-21. this only happens when I go from P-51 to another plane without exiting the whole game. I hope i am making sense.
