There's full support, and compatibility with DirectX 10 and 10.1 hardware, and this support extends too new DirectX 11 hardware. A new compute shader technology will open a GPU's capabilities to coincide as a parallel processor. More optimized power as multi-threaded resource handling will increase performance on multi-core machines. That's great since 8-core processors are not far-off from market sale. The last technical DirectX 11 feat announced is support for tessellation, a big fancy term that more or less makes your graphics smoother and prettier when viewed close-up. It could be a year or more before a MMOG takes full advantage of DirectX 11's capabilities. For example early DX10 adopters that play MMOGs are still waiting for Age of Conan's DX10 client.
