Ray-traced 3D renderer Rendering on the GPU Fast Draft previews mode Faster blitting to the screen (OpenGL SwapBuffer) Cartoon effect's "Use OpenGL When Available" Hardware Accelerate Composition, Layer, and Footage Panels" preference Feature support levels There are three tiers or levels, from lowest to highest requirements, of support: Level 1: For OpenGL SwapBuffer: This level simply requires a GPU that can do OpenGL 1.5, or greater, with Shader Model 3.0, or greater. Most ATI and NVIDIA cards, and the Intel HD Graphics 3000 chipset (available in the MacBook Air, Mac Mini, various Windows machines, etc.) and 4000 (Windows only at this time) are supported. If your GPU does not support these requirements, software OS blitting like CS5.5 occurs, and there are improvements for software blitting in After Effects CS6, as well. Level 2: For Fast Draft previews, Hardware BlitPipe, and Cartoon GPU acceleration: Includes Level 1 features. This level requires OpenGL 2.0, or greater (with Shader Model 4.0, or greater, on Windows), and 256 MB, or greater, of texture memory. Most ATI and NVIDIA cards released in the past five years, plus the Intel HD Graphics 3000/4000, support this level. If your GPU does not support these requirements, these features will be disabled: Fast Draft mode The "Hardware Accelerate Composition, Layer, and Footage Panels" preference. The Cartoon effect's "Use OpenGL When Available" option (the Cartoon effect then runs on the CPU). Level 3: For Ray-traced 3D rendering on the GPU: Includes Level 1 & 2 features (for machines with attached monitors). This level requires a supported NVIDIA GPU and 512 MB, or greater, of texture memory. For a current list of supported GPUs, see the Adobe website. Install GPU drivers Before working with After Effects CS6 and CUDA features, install the latest video driver for your NVIDIA GPU: Windows: Install the latest WHQL-certified driver for your GPU: http://www.nvidia.com/page/drivers.html Mac OS: Install the NVIDIA CUDA driver (v4.0.50 or later): http://www.nvidia.com/object/mac-driver-archive.html You can update the CUDA driver via the CUDA panel in System Preferences or by going to the NVIDIA website. Note: If your GPU is not supported or you have an old driver, ray-traced 3D compositions render on the CPU using all physical cores. If you have a GPU-supported configuration in a headless environment (for example, a render farm), you can force ray-traced 3D compositions to render on the CPU by setting the Ray-tracer option in the GPU Information dialog box (available from Previews preferences). Renders done on the CPU match renders done on the GPU. Note: Mac 10.6.8 only: If you use a Quadro 4000 GPU, install the Quadro 4000 driver for Mac. For more information, see this blog post.
