I have a FX-8320 processor (3.5 ghz, but i overclocked it to 4.0 ghz) 16 gbs of GSkill ram, and a GTX 750 Ti. But when I play on deathmatch or casual, even arms race I experience frame drop. I don't know what could cause this. I usually run at 200 fps or no more below 150. But now I'm hitting only 50 fps or less. It is very frustrating.
