I have done my due diligence and searched all over for the answer, and have seen people in YouTube videos who appear to have a greater panning range using it. In the TrackIR software, I've tried turning the limits on and off, enabling/disabling TrueView, using different curves and so on. The display in the software will indicate rotations of 180 degrees (or more with limits off) but that never translates in Arma 3 to more than 90 degrees.
I don't think this is a TrackIR software issue per se, but any information that could help me solve this would be greatly appreciated.
