A primitive listing and sorting arrangement for a tile-based graphics rendering system in which primitive lists can be prepared for at least two different sets of sub-regions of the render target area. Two or more alternative solutions for listing the primitive for rendering using the sub-regions of at least two of the at least two different sets of sub-regions of the render target area that primitive lists can be prepared for are determined (S62). A cost function is then used to assess the cost of listing the primitive for each determined alternative primitive listing solution (S63) and the primitive listing arrangement to use is then selected based on the cost assessment (S64). Embodiments use an adaptive cost function that can be modified in use based on analysis of the costs for the primitive listing process actually being experienced in use. |
