Here are videos from the four demos from the benchmark of the game STALKER: Call of Pripyat in split screen mode, running in DirectX 10 mode on the left and with DirectX 11 on the right. The right part with DX11 also has Tessellation and Contact Hardening Shadows enabled, but there is hardly any difference visible in the fast running flybys in the benchmark. Hell, even when playing not only STALKER, but any other fast paced FPS game you probably won’t notice much of a difference simply because you won’t have enough time to inspect at shadows of objects or to look your surroundings in detail. DirectX 11 should be offering faster performance, but with tessellation and CHS enabled actually there is a performance drop (with hardly any visible difference), as you can see in the results, compared with the game running in DX10. BTW the test system was equipped with Radeon HD 5970 video card and a quad core Intel Core i5 CPU, but still the benchmark (in Ultra quality mode and 1680×1050 resolution!) has some moments with framerate of about 30-40 frames per second. stal
