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
I have just found this too. I was capping at 120 fps and finding it was ok, but still a bit stuttery now & then. About 20 mins ago I put my cap up to 125 fps and it is so much better. Had no idea about it being tied to the mouse polling rate but makes sense. Mine is at 1000hz, so maybe as it is divisible it runs smoother.
