MKB Simultaneous movement causes stuttering (not on controller)
Hello! I've been trying for, no exaggeration, months to solve this issue myself and with help from the community and i've hit such a wall there is genuinely nothing left that I know about on my end to try and solve. I hope that someone can please reach back out to help
The issue i am running into is a consistent, reproducible on my end camera stutter/jitter/stickiness when i use a mouse + keyboard on Steam.
If I am running, and move my camera at the same time, or running + jump + move camera, there is a very apparent stuttering that is occurring with the entire environment EXCEPT my players hands/gun. I;ve tried a DuckyOneTwo keyboard, a Corsair, and a Razer keyboard. Ive tried a Wired Logitech G 502 HERO mouse and a Razer V3 Basilisk mouse, all are causing the issue.
The issue is ENTIRELY gone if i plug in a wired Playstation 5 controller to my PC and use that. MKB always reproduced the issue.
im also utilizing G-sync and capped framerate to make sure it is not just graphical tearing but as I said before the issue is entirely non-present with a controller or it would be happening with both.
- Trigger: Movement key + jump + simultaneous mouse movement
- Result: Camera stutter
- Workaround: PS5 controller eliminates it entirely
- Hardware: i7-13700K, RTX 4090, ASUS PRIME Z790-A WIFI, Windows 11 Pro
- Tested and ruled out: Multiple mice (wired and wireless), multiple polling rates, Synapse/G HUB removed, DX11 and DX12, raw input on, overlays off, USB selective suspend disabled, clean drivers
