D3D12_SHADING_RATE enumeration (d3d12.h)

  • Article

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
} ;
