Did you watch the video ronnn linked to . Cinema2 is more than what you believe. Watch the video than listen at the end when he says that he will update us on more things like RTR. The Ruby demo was raytraced with ATI gpu. Transformers previews were done RTR on ATI GPU' I would say its going to get really interesting. I still believe it will be between ATI Intel . But thats with todays GPUs . What tomorrow brings is another day.
NV showing that demo was really really good. Game developers are Aware.
Its pretty good. ATI NV will have way better cards befor the larrabee release.
The thing that has me concerned is the shear amount of compute power RTR requires. So physics on the gpu may not be such a good move. We just have to wait and see how it turns out.
