A method for delayed frame buffer merging. The method includes accessing a polygon that relates to a group of pixels stored at a memory location, wherein each of the pixels has an existing color. A determination is made as to which of the pixels are covered by the polygon, wherein each pixel includes a plurality of samples. A coverage mask is generated corresponding the samples that are covered by the polygon. The group of pixels is updated by storing the coverage mask and a color of the polygon in the memory location. At a subsequent time, the group of pixels is merged into a frame buffer.
