Abstract: A system and a method are disclosed for post-processing variable pixel rate shader output using gradients in a graphics processing unit. A block of pixels is selected that corresponds to a predetermined kernel size for variable rate shading in a draw call of an application. A pixel shader run is instantiated to generate pixel shading values for at least two pixels located within the block of pixels. A gradient output is generated based on an interpolation of the pixel shading values for the at least two pixels over the block of pixels. The predetermined kernel size may include at least one of a 4×2 block of pixels, a 2×4 block of pixels, a 4×4 block of pixels, an 8×4 block of pixels, a 4×8 block of pixels, and an 8×8 block of pixels or larger. The at least two pixels may be corner pixels of the block of pixels.
