1. A method of carrying out a higher level of multisampled anti-aliasing in a graphics processing pipeline having a plurality of processing stages, at least some of which are configured to natively support a lower level of multisampled anti-aliasing, the method comprising:

  • when performing the higher level of multisampled anti-aliasing;

    the rasteriser of the graphics processing pipeline generating graphics fragments each representing a set of sampling points for the higher level of anti-aliasing, and passing those fragments to later stages of the graphics processing pipeline for processing;

    one or more of the later processing stages of the graphics processing pipeline processing each graphics fragment that they receive for processing in a processing pass that processes all the sampling points that the fragment represents in parallel; and

    one or more other later processing stages of the graphics processing pipeline processing each graphics fragment that they receive for processing in one or more processing passes, each such processing pass processing a sub-set of the sampling points of the set of sampling points that the fragment represents.
