Also check out the SmoothTrack mobile app. Same use case but the compute is done on a phone instead of the gaming machine. Head position data can be sent over local network or USB.
Just wanted to say thanks! The first time played Flight Simulator 2020 with SmoothTrack I was blown away. I still am blown away each time too. Great experience that’s been nearly flawless for me and really turned up the realism. I can move my head closer to gauges and see what they’re saying, look around stuff, get a better view out the window. Wonderful.
