D3DDDICAPS_SHADER_MIN_PRECISION_SUPPORT structure (d3dumddi.h)
Describes precision support options for shaders in the user-mode display driver.
Syntax
typedef struct D3DDDICAPS_SHADER_MIN_PRECISION_SUPPORT {
UINT VertexShaderMinPrecision;
UINT PixelShaderMinPrecision;
} D3DDDICAPS_SHADER_MIN_PRECISION_SUPPORT;
Members
VertexShaderMinPrecision
A combination of values of type D3DDDICAPS_SHADER_MIN_PRECISION that are combined by using a bitwise OR operation. The resulting value specifies minimum precision levels that the driver supports for the vertex shader. A value of zero indicates that the driver supports only the default precision for the shader model, and not a lower precision.
PixelShaderMinPrecision
A combination of values of type D3DDDICAPS_SHADER_MIN_PRECISION 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 the default precision for the shader model, and not a lower precision.
