I’ve been using a low budget head tracking setup in Arma and although it works well and gets the job done, I do experience an issue when I look at angles in excess of 45 degrees where my avatar will reduce movement speed to a walking pace. Has anyone else experienced this and know of a work around?
I'm currently running opentrack (https://github.com/opentrack/opentrack/releases) with a PlayStation Eye and an IR clip. The only actual configurations I've done for Arma is to enable head tracking in the options menu:
