Detailed Description

This describes the shading rate capability flags.

Member Enumeration Documentation

◆ Enum

enum xiiGALShadingRateCapabilityFlags::Enum : StorageType
Enumerator
None 

No shading rate capabilities.

PerDraw 

Shading rate can be specified for the whole draw call.

PerPrimitive 

Shading rate can be specified in the vertex shader for each primitive and combined with the base rate.

TextureBased 

Shading rate is specified by a texture, each texel defines a shading rate for the tile.

SampleMask 

Allows to set zero bits in graphics pipeline sample mask with the enabled variable rate shading.

ShaderSampleMask 

Allows to get or set SampleMask in the shader with enabled variable rate shading.

ShaderDepthStencilWrite 

Allows to write depth and stencil from the pixel shader.

PerPrimitiveWithMultipleViewports 

Allows to use per primitive shading rate when multiple viewports are used.

SameTextureForWholeRenderPass 

Shading rate attachment for render pass must be the same for all sub passes.

TextureArray 

Allows to use texture 2D array for shading rate.

ShadingRateShaderInput 

Allows to read current shading rate in the pixel shader.

AdditionalInvocations 

Indicates that driver may generate additional fragment shader invocations in order to make transitions between fragment areas with different shading rates more smooth.

NonSubSampledRenderTarget 

Indicates that there are no additional requirements for render targets that are used in texture-based VRS rendering.

SubSampledRenderTarget 

Indicates that render targets that are used in texture-based VRS rendering must be created with the subsampled flag. Intermediate targets must be scaled to the final resolution in a separate pass. If supported, rendering to the subsampled render targets may be more optimal.

Note
Both non-subsampled and subsampled modes may be supported by a device.
