...DXGI handles enumerating graphics adapters, enumerating display modes, selecting buffer formats, sharing resources between processes, and presenting rendered frames to a window or monitor for display. HLSL is the high-level shader language for DirectX. Using HLSL, you can create C-like programmable shaders for the Direct3D pipeline. The DirectDraw surface file format (DDS) supports uncompressed and compressed (DXTn) textures, mipmaps, cube maps, and volume maps.
