In terms of performance, the Radeon 2900XT 1GB rendered Transformers scenes in 20-30 frames per second, in 720p resolution and no Anti-Aliasing. With the Radeon 3870, the test scene jumped to 60 fps, with a drop to 20 fps when the proprietary Anti-Aliasing algorithm was applied. Urbach mentioned that the Radeon 4870 hits the same 60 fps – and stays at that level with Anti-Aliasing (a ray-tracer is not expecting more than 60 fps.) JulesWorld’s technology also works on Nvidia GeForce 8800 cards and above, but the lack of a tessellation unit causes a bit more work on the ray-tracer side.
