If you are working on a small part of your composition, limit which portion of the composition is rendered to the screen during previews. After Effects must use memory and processor resources to update open panels, which may slow the work that you are doing in another panel. Choose Edit > Preferences > Display (Windows) or After Effects > Preferences > Display (macOS), and select Hardware Accelerate Composition, Layer, And Footage Panels. Enable hardware acceleration of previews, which uses the GPU to assist in drawing previews to the screen.The speed and quality of color management for previews are controlled by the Viewer Quality preferences. See Simulate how colors will appear on a different output device. Turn off display color management and output simulation when not needed.Stop or pause resource-intensive operations in other applications, such as video previews in Adobe Bridge.If you run applications other than those with which After Effects shares a memory pool, and you don’t allocate adequate memory to other applications, performance can be greatly reduced when the operating system swaps RAM to the hard disk. Quit applications that are not necessary for your work.See the documentation for your operating system and computer for details on how to check the amount of installed RAM and how to install RAM. Optimum performance is achieved with computer systems with at least 2 GB of installed RAM per processor core. Make sure that your system has enough RAM.To download updates for drivers and plug-ins, go to the provider’s website.
