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。

必需的D3D10_或D3D11_ FORMAT_SUPPORT_* 枚举值	Direct3D 10Level 9 中的支持算法
BACK_BUFFER_CAST	对于支持 DISPLAY 的任何格式，假定为 true。
BLENDABLE	无FORMATOP_NOALPHABLEND
CPU_LOCKABLE	假定始终为 true。
DISPLAY	硬编码。
IA_VERTEX_BUFFER	D3DDTCAPS_* (请参阅 Note.)

MIP_AUTOGEN	(请参阅 Note.)
RENDER_TARGET	FORMATOP_OFFSCREEN_RENDERTARGET

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。
