D3D12DDI_SHADER_MIN_PRECISION enumeration (d3d12umddi.h)
The D3D12DDI_SHADER_MIN_PRECISION enumeration describes the driver's minimum precision support options for shaders.
Syntax
typedef enum D3D12DDI_SHADER_MIN_PRECISION {
D3D12DDI_SHADER_MIN_PRECISION_NONE = 0x0,
D3D12DDI_SHADER_MIN_PRECISION_10_BIT = 0x1,
D3D12DDI_SHADER_MIN_PRECISION_16_BIT = 0x2
} ;
Constants
D3D12DDI_SHADER_MIN_PRECISION_NONE Value: 0x0 The driver supports only full 32-bit precision for all shader stages. |
D3D12DDI_SHADER_MIN_PRECISION_10_BIT Value: 0x1 The driver supports 10-bit precision. |
D3D12DDI_SHADER_MIN_PRECISION_16_BIT Value: 0x2 The driver supports 16-bit precision. |
Remarks
The returned information just indicates that the graphics hardware can perform HLSL operations at a lower precision than the standard 32-bit float precision, but doesn’t guarantee that the graphics hardware will actually run at a lower precision.
