(adsbygoogle = window.adsbygoogle || []).push({}); Ok, well about 6 months ago i switched from a stock dell mouse to a Razer Deathadder. It seemed to work VERY well. but after 6 months when i move my mouse in a game ,such as Call of duty games, counter strike, day of defeat, left 4 dead, my FPS goes down from about 120 to 9... I've tried uninstalling the games and drivers and such but nothing worked... Someone please help?

If you want my specs just ask

your mouse has very high DPI so you are turning faster now therefore the pc has to render out all the objects in each frame when u say do a 720 spin therfore you lagg up

Thats true also it is a dell lol. Next time go with hp, or alienware.
