Recently, I've encountered this weird problem.

Regardless of what game I play, my mouse sensitivity seems to constantly change as I play. Especially noticeable in csgo, overwatch and rust. For example, it'll be sharp, crisp and fast one second, but then a few seconds later, it'll feel slow like it's lagging behind. I tried ignoring it at first since it's possible it's just in my mind, but I'm now pretty convinced it's actually happening.

I've tried everything. I've even repair installed windows. I'm just about at my wits end, and I'm willing to buy a new mouse at this point, but I'm unsure whether or not that'll fix my problem.
