DX11: Unigine Heaven 2.5
The Unigine Heaven 2.5 benchmark is a free publicly available tool that beautifully demonstrates the DirectX 11 graphics capabilities in Windows 7 or updated Vista Operating Systems. Set among an enchanting village built on floating islands connected by swaying rope bridges, Heaven uses advanced lighting, tessellation, smoke and particle effects, distance blur, and a host of other graphical techniques to render a photo-realistic experience. An interactive mode allows for manual exploration of the village. Of course, all of this requires considerable graphics muscle, and I've found Heaven to be an excellent tool for testing the stability of graphics card overclocks.
The distinguishing feature in the Unigine Heaven benchmark is a hardware tessellation that is a scalable technology aimed for automatic subdivision of polygons into smaller and finer pieces, so that developers can gain a more detailed look of their games almost free of charge in terms of performance. Thanks to this procedure, the elaboration of the rendered image finally approaches the boundary of veridical visual perception: the virtual reality looks real. The "Heaven" benchmark excels at providing the following key features:
NVIDIA pulls back into the lead here, with the GTX560 just matching the stock-clocked HD6950, and the GTX570 posting scores about 12-13% better than the overclocked HD6950.
