DirectX 11 belongs to Windows 7
 

As Windows 7, codenamed Vienna is an improved version of Vista, DirectX 11 will work on both systems. It looks that DirectX 11 will launch before Windows 7 and we have high hopes of seeing DirectX 11 by the end of 2009.

DX11 is based on DirectX 10 but naturally it has more options including Tessellation, compute Shaders - something good for Cuda and GPGPU, CPU multithread support and some new texture compression. Let’s not forget Shader model 5.0 but at this time we don’t know enough about it.
