D3D11_FEATURE_DATA_D3D9_OPTIONS1 structure

Note  This structure is supported by the Direct3D 11.2 runtime, which is available on Windows 8.1 and later operating systems.

Describes Direct3D 9 feature options in the current graphics driver.

Syntax


typedef struct D3D11_FEATURE_DATA_D3D9_OPTIONS1 {
  BOOL FullNonPow2TextureSupported;
  BOOL DepthAsTextureWithLessEqualComparisonFilterSupported;
  BOOL SimpleInstancingSupported;
  BOOL TextureCubeFaceRenderTargetWithNonCubeDepthStencilSupported;
} D3D11_FEATURE_DATA_D3D9_OPTIONS1;

Members

FullNonPow2TextureSupported

Specifies whether the driver supports the nonpowers-of-2-unconditionally feature. For more info about this feature, see feature level. The runtime sets this member to TRUE for hardware at Direct3D 10 and higher feature levels. For hardware at Direct3D 9.3 and lower feature levels, the runtime sets this member to FALSE if the hardware and driver support the powers-of-2 (2D textures must have widths and heights specified as powers of two) feature or the nonpowers-of-2-conditionally feature.

DepthAsTextureWithLessEqualComparisonFilterSupported

Specifies whether the driver supports the shadowing feature with the comparison-filtering mode set to less than or equal to. The runtime sets this member to TRUE for hardware at Direct3D 10 and higher feature levels. For hardware at Direct3D 9.3 and lower feature levels, the runtime sets this member to TRUE only if the hardware and driver support the shadowing feature; otherwise FALSE.

SimpleInstancingSupported

Specifies whether the hardware and driver support simple instancing. The runtime sets this member to TRUE if the hardware and driver support simple instancing.

TextureCubeFaceRenderTargetWithNonCubeDepthStencilSupported

Specifies whether the hardware and driver support setting a single face of a TextureCube as a render target while the depth stencil surface that is bound alongside can be a Texture2D (as opposed to TextureCube). The runtime sets this member to TRUE if the hardware and driver support this feature; otherwise FALSE.

If the hardware and driver don't support this feature, the app must match the render target surface type with the depth stencil surface type. Because hardware at Direct3D 9.3 and lower feature levels doesn't allow TextureCube depth surfaces, the only way to render a scene into a TextureCube while having depth buffering enabled is to render each TextureCube face separately to a Texture2D render target first (because that can be matched with a Texture2D depth), and then copy the results into the TextureCube. If the hardware and driver support this feature, the app can just render to the TextureCube faces directly while getting depth buffering out of a Texture2D depth buffer.

You only need to query this feature from hardware at Direct3D 9.3 and lower feature levels because hardware at Direct3D 10.0 and higher feature levels allow TextureCube depth surfaces.

Remarks

You can use the D3D11_FEATURE_D3D9_OPTIONS1 enumeration value with ID3D11Device::CheckFeatureSupport to query a driver about support for Direct3D 9 feature options rather than making multiple calls to ID3D11Device::CheckFeatureSupport by using D3D11_FEATURE_D3D9_OPTIONS, D3D11_FEATURE_D3D9_SHADOW_SUPPORT, and D3D11_FEATURE_D3D9_SIMPLE_INSTANCING_SUPPORT, which provide identical info about supported Direct3D 9 feature options.
