I've had mouse lagging and don't use Explorer. I use a third party file manager. I had assumed it was related to Defender running in the background and currently have it disabled. At first I thought it was my Windows getting overbloated. So my first step in trying to fix was to reinstall Windows. That didn't work either.Have they fixed the bug where if you drag windows with file explorer in the background the mouse lags when at high polling rate(500hz+)? It's pretty frustrating.
