I have been using TrackIR 5.0.300 software with my Track IR 4 (Clip) and have always thought that the Limit function for Pitch should be set at +90 and -90 degrees, and not +180/-180 degrees. This quickly prevents the effect of my head falling off backwards when looking up too far.
To prevent my virtual head falling off, I worked out (what you showed in another post) and pull the graph line down to zero where I want my head to turn no further ... so that I can program the 90 degree limit with a bit of fiddling.
I thought this would be an "easy thing"
to do in the software and would make setting up more intuitive and (initially) quicker.Regards,
George.
