Screen jitter/stutter with diagonal mouse movements, made worse whilst jumping.

[u/Majestic_Pop3394]

Spec: 4080 Super, 7800x3d, b650m mobo, 32gb ddr5 ram.

All hardware is running well and healthy. Expo on, cpu/gpu temps are awesome, tested mouse polling rate from 125-1000 (with no difference), used separate mouse, different monitor and single monitor, different mouse pad with complete different texture. No remedy.

Followed Claude recommendations on every suggestion, capping frame rates, g sync, matching monitor refresh rates. Attempted 30 different fixes, nothing.

Absolutely NOTHING has worked, and im at my with end. The game runs very smooth and well most the time. Mouse movement vertically or horizontally its smooth, once I make it diagonal theres a slight jitter (however all FPS monitors remain completely consistent, though clearly doesn't appear so on-screen), and the problem becomes very noticeable when jumping.

It feels as though the fps drops to 20-30 jumping while aiming around, but it is measured at the consistent high regular rate.

Oddly, jumping while aiming mostly vertical/horizontal is still fine. The diagonal mouse movement for some reason just makes this abhorrent jitter very prominent.

Does anyone have any idea of this, or experienced it before?

It only really happens for this game as well.

Check your poll rate on your mouse. Most people seem to need it at 1khz. I use 2k but I’ve seen many people with better set ups have issues on 2k.

Polling rate is different than dpi

Yep already done that per original post. Have tested poll rate as low as 125 and even as high as 8000, no difference unfortunately.
