Symptoms

Mice with high polling rates cause heavy fps drops when moving camera with mouse. This affects other "Kex engine" games as well such as BLOOD: FRESH SUPPLY (which I cannot file a report on due to me owning the gog version of that game and using third party tools to use proton with it)

Reproduction

Start a new game and use a high polling rate mouse to move camera
