TrackIR stuttering in Black Thursday

[hughlb]

Despite maintaining a high framerate (90-120 FPS), there is significant stuttering when looking around with TrackIR in the second part of Black Thursday (the air battle with bomber formations) - it looks like 30fps despite having a high framerate, and it doesn't improve when moving away from the bomber formation. During the takeoff and landing sequence there is no issue, and TrackIR is smooth. Lowering graphics settings makes no difference.

I have same issues with trackIR lagging when Load is above 60% - in single player mission Black Thursday. This is because whole simulation is run locally. Something could be done to make tracking smooth despite this high load , I believe only those huge bombers formation optimization or move AI calculation to GPU???
