Mouse Sensitivity cycling every second or so.

[Landjrin]

Difficult to describe, basically the mouse sensitivity is switching between two different sensitivities on a cycle of about 1 second, fast/slow/fast/slow/etc
Both sensitivities are impacted by the in-game sensitivity slider, behavior is only present in-game does not occur anywhere else on my computer or in menus.

Specs:
Ryzen 7 5700x
32gb RAM
RTX 3060
Windows 10

Frame rate is rock solid.

Mouse is a Logitech G502 Hero, I've tried switching between borderless windows and fullscreen and disabling G-Hub.

Needless to say this makes aiming impossible. I've attached a clip of it here, in the clip I am moving the mouse in a perfect circle on my mousepad.

Build is the latest as of 5/30/24

Bump

Did some more experimentation, the issue is alleviated when running the game at significantly higher framerates.

At 70~ FPS on the "Best Looking" preset the issue is most visible
At 270~ FPS on the "Fastest" preset the issue is still present but significantly alleviated

Monitor is 1440p 144hz, but in these tests I was running the game at 1080p windowed.

on "Best Looking" it felt like the sensitivity "flickering" was most significant, like flickering between 30% and 100% sensitivity.

while on "Fastest" the issue is still present but significantly reduced, more like flickering between 90% and 100% sensitivity.

issue does seem to be impacted most by framerate, as keeping everything on the "fastest" setting but scaling render resolution from 50% to 100% (thus decreasing framerate) directly effects the severity of the problem.

The good news is I can play now, the bad news is i can only play on potato graphics but not because my system can't run the game at "best looking" but because my sens is tied to the framerate for some reason.
