|Colin McRae Dirt 2: DirectX 9 vs. DirectX 11|
In a direct comparison the differences on the audience only become noticeable if you get close and pay attention - some more polygons in the right place make the figures look a little better. The flying flags are "nice to have" while the improved water visualization is really good: The car really ploughs through the water and builds up a little bow wave - additional particles on splashes make the whole scene more realistic. But the biggest difference between DirectX 9 and DirectX 11 is the illumination. Due to HDAO and nice Post Effects the visual appearance of Dirt 2 with DirectX 11 is less "overbright" and smoother. The more realistic look of the DirectX 11 version might convince some players, since there have already been mods for Race Driver Grid that were reducing exactly those warm colors and thus created a more real appearance.
We are currently working on benchmarks to demonstrate the difference in performance between DirectX 9 and DirectX 11.
