Hey, Koroush is on top of things, I tell ya. The G.R.A.W. demo was only released last Wednesday, & he's already got his tweak guide published.

"Note that the demo and the retail version are essentially identical in terms of performance and tweaking, and as such download the demo and tweak it using the guide, as this will give you a genuine idea of how good the retail version will look and perform on your system."
