That's the million dollar question.
There must be a lot of miss-configured PCs out there then...lol
Either this, or the game makes some exception with some of the new hardware. And that's difficult to believe really. More believable would be to assume it's driver related.
Also I'm not sure if it's game related and i wanna emphasize this, as i (personally) doesn't encountered any graphical glitches or even crashes. Not a single one.
That's kind of strange, if you take to consideration that my CPU is a dual core, and doesn't even meet the min. req. (actually it's -12% below)
Of course I'm happy, and it would be stupid to complain about...
