D3D11_FEATURE_DATA_SHADER_MIN_PRECISION_SUPPORT structure (d3d11.h)

  • Article
Note  This structure is supported by the Direct3D 11.1 runtime, which is available on Windows 8 and later operating systems.
 
Describes precision support options for shaders in the current graphics driver.

Syntax

typedef struct D3D11_FEATURE_DATA_SHADER_MIN_PRECISION_SUPPORT {
  UINT PixelShaderMinPrecision;
  UINT AllOtherShaderStagesMinPrecision;
} D3D11_FEATURE_DATA_SHADER_MIN_PRECISION_SUPPORT;

Members

PixelShaderMinPrecision

A combination of D3D11_SHADER_MIN_PRECISION_SUPPORT-typed values that are combined by using a bitwise OR operation. The resulting value specifies minimum precision levels that the driver supports for the pixel shader. A value of zero indicates that the driver supports only full 32-bit precision for the pixel shader.

AllOtherShaderStagesMinPrecision

A combination of D3D11_SHADER_MIN_PRECISION_SUPPORT-typed values that are combined by using a bitwise OR operation. The resulting value specifies minimum precision levels that the driver supports for all other shader stages. A value of zero indicates that the driver supports only full 32-bit precision for all other shader stages.

Remarks

For hardware at Direct3D 10 and higher feature levels, the runtime sets both members identically. For hardware at Direct3D 9.3 and lower feature levels, the runtime can set a lower precision support in the PixelShaderMinPrecision member than the AllOtherShaderStagesMinPrecision member; for 9.3 and lower, all other shader stages represent only the vertex shader.
