1. A method of producing a frame using a tile-based graphics processor for output to a display, comprising:
generating a tile representation of the frame, wherein the tile representation comprises a plurality of tiles each associated with an area of the frame, each said tile being of a fixed size and comprising a plurality of portions;
eliminating one or more of the plurality of portions of each tile;
rendering retained portions of each tile to produce rendered tiles;
transforming the rendered tiles into processed compressed tiles;
outputting the processed compressed tiles to memory for display,
constructing the frame from the processed compressed tiles; and
outputting the constructed frame to a display;
wherein transforming the rendered tiles into processed compressed tiles comprises combining at least two rendered tiles by combining the data associated with each of the rendered tiles into a processed tile of the fixed size.
