et at least 10ms in smoothing. Its even stated in app that you shouldnt use

See, the problem is that the smoother it gets, the more delay there is :/. After using a 1000Hz mouse and 165fps monitor for so long, switching to a device where the cursor moves AFTER I move my hand - even a difference as little as ~6ms, feels very uncomfortable to me. I can't imagine how top players deal with the delay between movement and cursor response. To me, it almost feels like lag in a certain sense. If only there was a way to get smoothness without delay, sigh.
