Probably another placebo but give it a try (floaty mouse in games fix)

Tweaked my registry so many times and after that still no fix for floaty mouse.
Just use sfc /scannow in CMD.
After that in powershell type

Remove-Item -Path "HKCU:\Control Panel\Mouse" -Recurse -Force

which is deleteing corrupted or modded values of mouse entries.
Reboot.
Do not forget to disable Enhance pointer Precision after the reboot
Try this out
Hope you feel positive changes after that.
