Can’t tell for sure either. It Lag feels slightly higher but perfectly fine for trying some head tracking without investing in additional hardware. This depends a lot on the processing power, of course. Cam doesn’t matter that much. It seems to read with only ~540 px width or something and any webcam of the last decade should manage ~50 fps with that 🤔
I’m also uncertain what the current penalty is for running this on Wayland via gamescope, which is really bringing my rig to it’s limits.
It does have some protocol overlaps especially for UDP. Not that it’s very complicated but it helped me when I implemented this in FreeSpace Open to get head tracking working on Linux PC too 🤓
