as I already stated several times, trackir is perfeclty set up: i have a 27' monitor and i am about 50 cm from trackir unit, sensors are centered, the unit is on the left above the monitor as I am using the proclip, there is no light disturbing/interfering with trackir, it only detects 3 sensors leds, no other lights detected, i have no mirrors, OS is installed from scratch, I play in a dark ROOM.
It's not a setup issue it is something different, tried vsyn,off,on,adaptive,in game,off game, gsync on/off, all combinations of gsync and vsync, , gsync off, vsync off, gsync off, vsync on, etc etc etc.
It is smooth only at perfect 120fps or 60
