Okay I play Half Life 2 roleplay most of the time and for some reason I'm only getting 50-60 FPS? Sometimes it will go to 100FPS but then shoot back down to like 30s,40s,and 50,s. I don't understand what's going on, I tried updating my video card drivers but nothing. I would expect more FPS on this game with my computer.

Any help?
