Abstract
Techniques for performing shader operations are provided. The techniques include, performing pixel shading at a shading rate defined by pixel shader variable rate shading (“VRS”) data, and updating the pixel VRS data that indicates one or more shading rates for one or more tiles based on whether the tiles of the one or more tiles include triangle edges or do not include triangle edges, to generate updated VRS data.

A method comprising:
- rendering graphics data to generate rendered graphics data using a set of variable rate shading (“VRS”) data;
- and
- generating a set of VRS rate feedback data for operations subsequent to the rendering, the set of VRS rate feedback data including modifications with respect to the set of VRS data, the modifications being associated with portions of the graphics data at which one or more triangle edges occur, wherein generating the set of VRS rate feedback data includes modifying VRS rates specified by the VRS data based on depth test results.
