The Unigine Heaven Demo is unique in that it is the only demo which allows for the following components in one package.

  • Synthetic Demo (i.e., a demo designed to "test" a system)
  • Comparable tests of DX9, DX10 and DX11
  • Is Hor+ (rather than limited to a few predefined aspect ratios)

The ability to compare DX9, DX10 and DX11 in the same environment allows for the unique ability to see how the different cards perform across these different comparable environments.

For the widescreen scores on the right side, I averaged the scores for the DX9, DX10 and DX11. They were also averaged for the Eyefinity scores on the 5870 2GB Eyefinity6 card. The remaining Eyefinity scores are only the DX9 scores. The percentage gains in the DX10 and DX11 scores (i.e., 1fps vs. 3fps - 300% increase) throws off the averages and isn't indicative of playable performance.
