It is a long shot and I am not sure if this is the same problem, but I had been popping out of the cockpit way above the aircraft, when I would re-center in DCS, I would lose the head up down/lean function (like my head was stuck on a stick), then it would pop back down again and full movement would return forcing me to keep re-centering. In combination, tracking was getting super delayed intermittently for about 15-30 seconds every couple of minutes. I was about to just give up and put the thing on the shelf after a ton of testing, to include mobo swaps for upgrade USB to 3.2 and I was about to buy a new CPU.
I have only done 1 test but things look resolved. (As kooky as it sounds) Replacing my lightbulbs with non LED (CFL or incandescent) and turning off my monitors. Make sure nothing that flickers or operates on a HZ is within sight of the headset.
My wife came in the room and turned on a LED light and it started stuttering again so I suspect LED bulbs in the room operating on different HZ screws with the unit.
If I run into the issue operating on non LED bulbs I will come back and correct myself, but I played for several hours today without encountering the issue which had been persistent before replacing my lighting.
