Interesting demo, they certainly have added a lot more interesting content and tessellation.
On my XFX 5850 Black Edition, no tessellation, 1280*1024, no AA, no AF:
DX9 = 90.8
DX10 = 89.4
DX11 = 76.3
GL 3.2 = 61.4
It looks like ATI still need to do a lot of work on their OpenGL performance!
I also hope that they will make an OpenGL 4.0 version with tessellation.
