1. A computer-implemented method for providing compression in graphics rendering comprising:
determining a plurality of values associated with individual pixels of a tile of pixels; determining, based at least in part on the tile of pixels, a plurality of pixel regions, wherein each pixel region comprises a corresponding subset of the individual pixels; determining, for an individual pixel region of the plurality of pixel regions, the subset of values associated with the subset of individual pixels corresponding to the individual pixel region comprises a single distinct value; setting a pixel region value for the individual pixel region to a bit value indicating the individual pixel region comprises the single distinct value; determining, for a second individual pixel region of the plurality of pixel regions, the subset of values associated with second individual pixels in the second individual pixel region comprises two or more distinct values; setting a second pixel region value for the second individual pixel region to a second bit value indicating the second individual pixel region comprises the two or more distinct values; and storing, in memory, graphics data comprising the pixel region value and the single distinct value associated with the individual pixel region, wherein the graphics data further comprises the second pixel region value and the two or more distinct values corresponding to the second individual pixel region.
