My problem is driving me crazy, I don't know what to do anymore. I’m having weird mouse problems when playing games (mouse becomes fast and slow, is inaccurate and sometimes unresponsive), I think it may have to do with electricity as I’ve changed every part of my PC trying to fix the issue and there is no clear explanation why I’m having such problems. I never had such an issue and the last thing in my mind is electricity. I'm thinking about getting a double conversion UPS maybe that would fix my issue? I have good FPS, for example in CSGO I get 500+ fps but the mouse movement is nowhere smooth as it was. I've tried tweaking bios settings, windows settings, of course turned off G-SYNC and V-SYNC, turned off mouse accell and no results. Please, help :C
