A graphics processing system performs filtering of oversampled data during a scanout operation. Sample values are read from an oversampled frame buffer and filtered during scanout; the filtered color values (one per pixel) are provided to a display device without an intervening step of storing the filtered data in a frame buffer. In one embodiment, the filtering circuit includes a memory interface configured to read data values corresponding to sample points from a frame buffer containing the oversampled data; and a filter configured to receive the data values provided by the memory interface, to compute a pixel value from the data values, and to transmit the pixel value for displaying by a display device, wherein the filter computes the pixel value during a scanout operation.
