Matching my mouse polling rate and framerate cap seemed to have fixed the mouse camera movement stutter
Luckily, my PC can maintain a locked 125FPS. So in my case, I set my mouse polling rate to 125Hz and capped the game to 125FPS
I experimented and found that the mouse camera stutter would only happen if my FPS are not exactly 125FPS.
This is on a 175HZ G-Sync Ultimate display with G-Sync on and Vsync on in the Nvidia control panel. Used Riva Tuner to cap my FPS
Omg this actually worked! tried 140 and 160 fps but had this stutter/jitter the whole time. Locked it to 125 and now its buttery smooth. Sadly my CPU is to slow to keep it consistent, so as soon as i drop even a few fps the jitter is back
