Abstract: This disclosure provides systems, devices, apparatus, and methods, including computer programs encoded on storage media, for backface culling for guard band clipping primitives. A graphics processor may identify at least one backface primitive in a set of primitives that extends beyond at least one guard band, where the at least one backface primitive is identified based on a set of fixed point coordinates. The graphics processor may cull the at least one backface primitive. The graphics processor may transmit an indication of the culled at least one backface primitive.

Abstract: Aspects presented herein relate to methods and devices for graphics processing including an apparatus, e.g., a GPU. The apparatus may receive a plurality of primitives associated with one or more frames in a scene, a portion of the scene being associated with an upscaled sample space and/or a downscaled sample space. The apparatus may also perform a binning pass for the plurality of primitives, the binning pass being associated with an unscaled sample space, where the binning pass sorts each of the primitives into one or more bins associated with each of the one or more frames. Further, the apparatus may perform one of one or more rendering passes for each of the one or more bins. The apparatus may also rasterize each of the plurality of primitives based on at least one of the upscaled sample space or the downscaled sample space.
