OpenGL is a set of standards for high-performance processing of 2D and 3D graphics on the graphics processing unit (GPU) for a wide variety of applications. OpenGL provides fast rendering for previews (Fast Draft mode).
After Effects can take advantage of GPU (graphics processing unit) on your graphics card for some specific kinds of processing.
The GPU features in After Effects are of the following 3 categories:
- GPU-accelerated ray-traced 3D renderer (CUDA on specific graphics cards)
- Fast Draft mode and Hardware BlitPipe (OpenGL with somewhat stringent requirements)
- OpenGL swap buffer (OpenGL with looser requirements)
IMPORTANT: In general, After Effects does not require CUDA features of any specific set of Nvidia GPUs. Only the GPU-accelerated ray-traced 3D renderer requires this. The other GPU features work on any GPU that meets certain basic requirements, including AMD and Intel GPUs. Continue reading for more features.
