I don't suppose it makes you feel any better to know that even the real entusiasts, with eight core processors, eight gig of RAM, and two nVidia GeForce 8800GTX 768mb graphics cards in SLi, have difficultly running the demo on High settings, let alone Very High?

It's a crazy system hogger. And the first time I've epxerienced something that means hardware needs to catch up with it, rather than the other way round.
