30 CrossFire™ Rendering Modes Alternate Frame Rendering (AFR) Mode In this mode, all even frames are rendered on one GPU, while all odd frames are rendered on the other. The completed frames from both GPUs are sent to the display. By allowing both GPUs to work independently, AFR provides the greatest potential performance improvements of all the available modes. It is also the only mode that allows the full vertex processing performance of both GPUs to be combined. 1 Radeon® X1950 Pro Graphics Card 2 Radeon® X1950 Pro Graphics Card 3 Frame Rendered on Radeon® X1950 Pro Graphics Card 4 Frame Rendered on Radeon® X1950 Pro Graphics Card 5 Final Rendered Frame on Display The main limitation of this mode is that it cannot be used in applications where the appearance of the current frame is dependent upon data generated in previous frames, since AFR generates successive frames simultaneously on different GPUs. In these cases, the SuperTiling or Scissor Mode is used instead. Super Anti-aliasing Mode Anti-aliasing (AA) is a rendering technique designed to remove jagged edges, shimmering, and pixelation problems that are common in rendered
