Same thing happened to me with my TrackIR 3D. I posted it as a bug with this game release but got no answer. So I will conjecture HTC wants us to move into the full 6-axis TrackIR capabilities.
I was using the old 4.1.37 software to get (x, y) Dot tracking mode. It would use my hps file settings for views. I finaly downloaded the 5.3 TrackIR software today and put the 3 dot track clip on my hat and started using 6-axis mode. The 5.3 software is excellent and now if I move my body and head about like looking around and over my shoulder in a real cockpit I see back and around or any of the other views I relied on the hps files for.
Make sure your camera is about 24-30 inches away from your hat or clip.
