A month and a half ago we showed you a picture of a stone rendered in DirectX10 on an R600, and ATI just confirmed that on its official page

You can see that our stone from here and ATI's from here are the same. The stone comes from the Call of Juarez game that uses DirectX 10 and the benchmark is floating around, but we haven't been able to get our hands on it yet.

I guess that proves a few things.
