Required DXGI formats
This topic presents the requirements that Microsoft Direct3D feature levels place on the user-mode display driver.
The first and second columns of the first table show all Direct3D format types that the driver must support. The third column shows all associated constant values of the Direct3D D3D10_FORMAT_SUPPORT and/or D3D11_FORMAT_SUPPORT enumerations that the driver must support. The fourth column shows the minimum Direct3D feature level at which the driver must support each format.
The second table shows the Direct3D 10Level 9 support algorithm for each enumeration value.

Note These are further details on the support algorithm's requirements in Direct3D 10Level 9:
- The IA_VERTEX_BUFFER and/or IA_INDEX_BUFFER formats are supported by software vertex processing if there is no D3DDEVCAPS_HWTRANSFORMANDLIGHT capability.
- The TEXTURE2D format can also be inferred from it being a depth-stencil format.
- For the SHADER_SAMPLE format, the driver must support FORMATOP_TEXTURE, FORMATOP_VOLUMETEXTURE, or FORMATOP_CUBETEXTURE, and it must not report FORMATOP_NOFILTER.
- For the MIP_AUTOGEN format, Direct3D 10Level 9 generates its own mip-maps, so it requires MIP, RENDER_TARGET, and TEXTURE2D bits.
