Polling Rate Issue

[ItsJAQ]

I'm having an issue, when my polling rate is 1000hz I get a lot of mouse acceleration. My solution was to drop it to 125hz, and that worked great for about 12 hours. Now however, when my polling rate is 125hz my video is really choppy/laggy. I bumped it back up to 1000hz and its perfectly smooth. Not sure if anyone else has had this issue or knows of a solution. Thanks for reading!
