I play Starcraft II and Battlefield 3. Normally my fps is about 100-120.
But recently for some reason my average fps suddenly drops to 20. I tried to lower my settings from ultra to low, it didn't work.... the frame rates are the same. Even on Starcraft II, pvp are unplayable so are the arcade games. Here's my specs:
GPU: hd7990
CPU: I7 4770k
PSU: 1200W xilence
RAM: 16gb corsair vengeance pro
MB: Asrock z77-itx
 
Solution
What are your temps when gaming? Could be overheating. I can't think of much else that could be causing that dramatic of a drop in fps. Are your AMD drivers up to date?

Wow.... I feel soo dumb. I never worried about the temperature because i always keep a close eye on the temp of the GPU and ignoring the CPU... for some reason my CPU is running 90C.. Imma fix that :) thx
