Member Enumeration Documentation

Enumerator
Unknown	Variable shading rate is not supported.
Palette	Single channel 8-bit surface that contains shading rate values. Only 2D and 2D array textures with R8UNormalized format are allowed.
RG8UNormalized	RG8UNormalized texture that defines the shading rate (0.5, 0.25 etc.). The R channel is used for X axis, G channel is used for Y axis.
ColumnRowFloat32	This format is only used in Metal when shading rate is defined by column/row rates instead of a texture. The values are 32-bit floating point values in 0 to 1 range (0.5, 0.25 etc.).
