GPU Features in After Effects 6
Todd Kopriva has an article on GPU acceleration in After Effects CS6 including CUDA and OpenCL.GPU-accelerated ray-traced 3D renderer (CUDA on specific graphics cards)Fast Draft mode, Hardware BlitPipe, and GPU acceleration of Cartoon effect (OpenGL with somewhat stringent requirements)OpenGL swap buffer (OpenGL with looser requirements)Looking forward to more speed in AE, even if most still has to be rendered (though with the RAM saving it may need a lot less rendering).
