Recently I'v had fps issues. My pc is relativly brand new and meets the recommended requirments of all the games i play (overkill in-fact) however every game has started to drop in FPS except for Battle Field 3. I've had this problem before and i solved it by wiping all my AMD graphic drivers and re-installing from factory defaults and updating. However this time it didnt work. Iv done that process 2-3 times with no avail. Iv noticed huge FPS lag in Teamfortress 2 and League Of Legend but i run Battlefield 3 at a steady 80 fps. While running the other games at about 15-30. Also I know over heating is not an issue because when running battlefield 3 my temps barly reach 70 degrees and when playing tf2 and league of legends they only reach about 55 degrees. Anyways please help me, i am very frustrated and dont really want to do a Windows re-install

Exactly what im thinking, has to be drivers or software problem in my oppinion, although i think a fresh windows re-install should fix things up......

EDIT!!
**SOLVED**
So apperntly it wasnt my GPU or anything on the video side at all. Basically my mouse was causing the lag as it would only drop fps when i would move my mouse. Most of the games I play require a mouse so I didnt notice right away but I moved my mouse down to 125hz and its fixed everything. Still dont know WHY its all wierd at 1000hz but whatever, I fixed it so Im happy.
