I just purchased the TrackIR 5 w/Trackclip Pro for ARMA II. I am using the TrackIR5 Beta software, and need help in just setting up the head alignment. What do I look for regarding the X-Y axis graphs? What are the 3-color vectors used for? I dowloaded the NaturalPoint TrackIR Users Manual version 5.0, but it doesn't go into detail in explaing what you're trying to accomplish and what you need to do to align your head using the software.
