D3D12_SHADING_RATE enumeration (d3d12.h)

Defines constants that specify the shading rate (for variable-rate shading, or VRS). For more info, see Variable-rate shading (VRS).

Syntax

typedef enum D3D12_SHADING_RATE {
  D3D12_SHADING_RATE_1X1 = 0,
  D3D12_SHADING_RATE_1X2 = 0x1,
  D3D12_SHADING_RATE_2X1 = 0x4,
  D3D12_SHADING_RATE_2X2 = 0x5,
  D3D12_SHADING_RATE_2X4 = 0x6,
  D3D12_SHADING_RATE_4X2 = 0x9,
  D3D12_SHADING_RATE_4X4 = 0xa
} ;

Constants

D3D12_SHADING_RATE_1X1 Value: 0 Specifies no change to the shading rate.
D3D12_SHADING_RATE_1X2 Value: 0x1 Specifies that the shading rate should reduce vertical resolution 2x.
D3D12_SHADING_RATE_2X1 Value: 0x4 Specifies that the shading rate should reduce horizontal resolution 2x.
D3D12_SHADING_RATE_2X2 Value: 0x5 Specifies that the shading rate should reduce the resolution of both axes 2x.
D3D12_SHADING_RATE_2X4 Value: 0x6 Specifies that the shading rate should reduce horizontal resolution 2x, and reduce vertical resolution 4x.
D3D12_SHADING_RATE_4X2 Value: 0x9 Specifies that the shading rate should reduce horizontal resolution 4x, and reduce vertical resolution 2x.
D3D12_SHADING_RATE_4X4 Value: 0xa Specifies that the shading rate should reduce the resolution of both axes 4x.
