D3D12_FEATURE_DATA_D3D12_OPTIONS6 structure (d3d12.h)

  • Article

Indicates the level of support that the adapter provides for variable-rate shading (VRS), and indicates whether or not background processing is supported. For more info, see Variable-rate shading (VRS), and the Direct3D 12 background processing spec.

Members

AdditionalShadingRatesSupported

Type: BOOL

Indicates whether 2x4, 4x2, and 4x4 coarse pixel sizes are supported for single-sampled rendering; and whether coarse pixel size 2x4 is supported for 2x MSAA. true if those sizes are supported, otherwise false.

PerPrimitiveShadingRateSupportedWithViewportIndexing

Type: BOOL

Indicates whether the per-provoking-vertex (also known as per-primitive) rate can be used with more than one viewport. If so, then, in that case, that rate can be used when SV_ViewportIndex is written to. true if that rate can be used with more than one viewport, otherwise false.

VariableShadingRateTier

Type: D3D12_VARIABLE_SHADING_RATE_TIER

Indicates the shading rate tier.

ShadingRateImageTileSize

Type: UINT

Indicates the tile size of the screen-space image as a UINT.

BackgroundProcessingSupported

Type: BOOL

Indicates whether or not background processing is supported. true if background processing is supported, otherwise false. For more info, see the Direct3D 12 background processing spec.
