必需的 DXGI 格式
本主题介绍 Microsoft Direct3D 功能级别对用户模式显示驱动程序所施加的要求。
第一个表的第一列和第二列显示驱动程序必须支持的所有 Direct3D 格式类型。 第三列显示驱动程序必须支持的 Direct3D D3D10_FORMAT_SUPPORT 和/或 D3D11_FORMAT_SUPPORT 枚举的所有关联常量值。 第四列显示驱动程序必须支持每种格式的最低 Direct3D 功能级别。
第二个表显示了每个枚举值的 Direct3D 10Level 9 支持算法。

注意 以下是 Direct3D 10Level 9 中有关支持算法要求的更多详细信息：
- 如果没有D3DDEVCAPS_HWTRANSFORMANDLIGHT功能，则软件顶点处理支持IA_VERTEX_BUFFER和/或IA_INDEX_BUFFER格式。
- 也可以从TEXTURE2D格式推断为深度模具格式。
- 对于SHADER_SAMPLE格式，驱动程序必须支持FORMATOP_TEXTURE、FORMATOP_VOLUMETEXTURE或FORMATOP_CUBETEXTURE，并且不得报告FORMATOP_NOFILTER。
- 对于MIP_AUTOGEN格式，Direct3D 10Level 9 生成自己的 mip 映射，因此需要 MIP、RENDER_TARGET 和 TEXTURE2D 位。
