Hey guys when i play Sc2 my Framerate per second (Fps) is like 30 at the beginning of a game but goes down lower as i play throughout the game. I've learned to deal with it. But recently my computer has been able to play on higher graphic settings and plays at over 60fps the whole game which rocked and i was playing VERY good beating players way higher than my skill level so of course i was beaming but one day i sign on and its back to its 30 fps terrible self. Now that i've experienced this great Fps i don't even want to play on it but if i could get my Fps back to 60 it'd be great. So i ask you why does it drop like that all of a sudden. Btw I'm on a Dell Xps laptop. Please if you know its my Graphics card my, motherboard Programs maybe virus please tell me Thanks so much in advance.
