A method for enhanced forward rendering is disclosed which includes a depth pre-pass, light culling and a final shading. The depth pre-pass minimizes the cost of final shading by avoiding high pixel overdraw. The light culling stage calculates a list of light indices overlapping a pixel. The light indices are calculated on a per-tile basis, where the screen has been split into units of tiles. The final shading evaluates materials using information stored for each light. The forward rendering method may be executed on a processor, such as a single graphics processing unit (GPU) for example.
