And how much RAM does your GRAPHIC card have?
Googling (which is what YOU should have done, not ME) for IntelĀ® 3100 integrated graphics says "up to 256mb" (while the bare minimum for nvn is "256mb or more"). But make sure have 256mb and not 128mb (= have your computer WRITE it).
You probably have an issue like
those guys. But tell me, why did you not find it, awesome man? Did you even look for it?
Oh and stupid thing, does you computer pass the dxdiag rendering tests?
PS: I you ever wondered why you have crappy performance in games, that's because your have an AWESOME GFX CARD MAANN (if you see "integrated" it sucks, period).
