Closing as a duplicate.

Symptoms
After > 30 minutes of gameplay the game becomes stuttery. When standing still and not moving the mouse no stutters occur. When moving with WASD no stutter occurs. When moving the mouse in combination of any of the preceding the stutter occurs. The issues are caused by the 1000 Hz polling rate of my mouse.
Workaround was found by adhering the advice in the link below. Setting the polling rate of the mouse to 500 Hz
Archwiki Polling rate resulting in lag with wine
Possibly reintroduced this bug?

Reproduction
