Your video card could be on its last limb?
might be the other way around, GS doesn't even use more than 50%
seems like the graphical bug changes whenever i shutdown my laptop, any ideas?
Yeah I'd say the graphics card is going bad in the laptop causing artifacting.
well i guess that is it, it is GeForce 320M anyway
does drivers also have anything to do with it? cuz i'm running it on Windows XP Bootcamp, not on Apple's native OS X
