Stone Giant is a benchmark tech demo that showcases and measures DirectX 11 performance using the BitSquid Engine. This is a very heavy tessellation dependant benchmark which runs very well on nVidia hardware.
At 1080p the card scored an average of 87 frames per second, which is basically more than double the frame rate the 6870 delivered when we last tested it at the same settings. Clearly this card is a tessellation powerhouse, without question.
