partially fixed Multiplayer only: "High" mouse polling rate (>999) causes fps drops and stuttering when moving mouse inside cockpit.

Logs: dcs.log dcs.log.old dcs.log

Notes: Only 1000hz seems to be affected. Moving mouse while interacting with cockpit elements prevent the bug from happening. Very slow movements prevent the bug from happening. Unable to reproduce on singleplayer. The issue is a lot worse when recording with a x264 cpu encoder instead of NVIDIA HEVC.

Additional notes: Inconsistent results after alt tabbing (it always stutters, but sometimes it's less severe). Less performance impact with freetrack protocol instead of TrackIR selected in opentrack. Even less performance impact with opentrack closed completely. Also present in the main menu when the game is in fullscreen at random (XD). Game gets frozen completly in single threading.

Mostly fixed with todays update, it can still be triggered if you move your mouse really fast over cockpit elements like switches and knobs.

it is still bad when I'm in VR and moving mouse with polling rate 1000hz - the cpu impact is nonsensically high
