This problem occurs every now and then, and it's a bit irritating.

I'm using a pretty powerful setup on my rig right now, yet I still suffer incredibly long load times and animation/sound lags in player dense areas (and sometimes not even then), as well as my frames dropping below 30. I'm told it has something to do with my CPU (dual core 3.2, overclocking it to 4.0) yet I know people who use as low as a i3 2.93hz and do not have the same problem as me (same ingame settings and everything).
