Methods and devices for performing pixel shading in graphics processing are described. Multiple primitives of an image can be shaded at one or more variable shading rates. A subset of pixels, in at least one screen-space tile corresponding to a portion of the image, corresponding to samples that are shaded in the shading at the one or more variable shading rates, can be determined. One or more deferred passes can be applied to the subset of pixels in the at least one screen-space tile to provide additional shading of the subset of pixels. After completing the deferred passes, the set of pixels not processed by the deferred passes can be filled using adjacent shaded pixels.
