Abstract
A graphics processing unit (GPU) may rasterize a primitive into a plurality of samples, wherein vertices of the primitive are associated with VRS parameters. The GPU may determine a VRS quality group that comprises one or more sub regions of the plurality of samples based at least in part on the VRS parameters. The GPU may fragment shade a VRS tile that represents the VRS quality group, wherein the VRS tile comprises fewer samples than the VRS quality group. The GPU may amplify the stored VRS tile into shaded fragments that correspond to the VRS quality group.
