While playing GUN or DOOM3, there is sometimes a hesitation during gameplay. It happens in DOOM when a hell-fiend is a bout to appear or in GUN when I enter a new part of town. I'm running both games at 1600x1200 and they are "beautiful." The frames rates are great, so I don't think it's the video card.
What should I do: increase Memory, turn down resolution, or get a new processor?
I've tried OCing the processor, but apparently doesn't allow this. I can adjust the Memory settings, but it won't let me change the FSB speed.
That may possibly be your hard drive loading the models for the hell-fiend. I haven't played D3 single player yet (mostly multiplayer). As for GUN, that could also be the hard drive loading up a new part of the map.
