DX11: 3DMark 11
FutureMark 3DMark11 is the latest addition the 3DMark benchmark series built by FutureMark Corporation. 3DMark11 is a PC benchmark suite designed to test the DirectX-11 graphics card performance without vendor preference. Although 3DMark11 includes the unbiased Bullet Open Source Physics Library instead of NVIDIA PhysX for the CPU/Physics tests, Benchmark Reviews concentrates on the four graphics-only tests in 3DMark11 and uses them with medium-level 'Performance' presets.
The 'Performance' level setting applies 1x multi-sample anti-aliasing and trilinear texture filtering to a 1280x720p resolution. The tessellation detail, when called upon by a test, is preset to level 5, with a maximum tessellation factor of 10. The shadow map size is limited to 5 and the shadow cascade count is set to 4, while the surface shadow sample count is at the maximum value of 16. Ambient occlusion is enabled, and preset to a quality level of 5.
3DMark 11's four graphics tests take the user through two underwater and two jungle scenarios. The underwater scenes (GT1 and GT2) do not use tessellation, but the jungle scenes (GT3 and GT4) do.
The AMD Radeons jump back into the lead on this test, and the overall ranking of these cards is similar to what we saw in the 3DMark Vantage tests. The Radeon HD6850 comes very close to the scores of the GTX 560, while the HD6590 dominates even when not overclocked.
The card rankings remain the same as in the first two tests, with the PowerColor Radeon PCS+ HD6950 continuing to dominate.
