1. A method of performing safety-critical rendering of a frame in a tile based graphics processing system, the method comprising:
receiving geometry data for the frame, including data defining a plurality of primitives representing a plurality of objects in the frame;
receiving a definition of a region in the frame, the region being associated with one or more primitives among the plurality of primitives;
receiving verification data that associates one or more primitives with the region in the frame; and
rendering the frame using the geometry data and controlling the rendering of the frame, so that the rendering excludes, from the frame inside the defined region, the primitives that are not identified by the verification data.
