Unigine has released the first DirectX 11 benchmark Heaven. The benchmark provides native support for OpenGL, DirectX 9, 10 and 11, and is available for free download.
"Heaven" benchmark excels at providing the following key features:
Native support of OpenGL, DirectX 9, DirectX 10 and DirectX 11
Comprehensive use of tessellation technology
Advanced SSAO (screen-space ambient occlusion)
Volumetric cumulonimbus clouds generated by a physically accurate algorithm
Dynamic simulation of changing environment with high physical fidelity
Interactive experience with fly/walk-through modes
The music to this benchmark is awesome!.. Anyway I gave it a try on my trusty old 4870 and it did ok...it even looked it was pumping out DX11..
Good app as usual from Unigine!
