Enhanced in After Effects CC 13.7 | January 2016
- Improved Cache Before Playback: The Cache Before Playback option enbales preview of frames as they are rendered. After Effects previews only the newly rendered frames and skips the previously rendered ones. The newly rendered frames are played back fast, depending on the monitor refresh rate, for example, 60Hz = 60fps.
Enhanced in After Effects CC 13.6 | November 2015
- Unified caching behavior: With the new caching behavior, After Effects stores only the screen display cache (a secondary cache used for transforming the frames for screen display) for a short duration ahead of the Preview Time Indicator. The new caching behavior results in previews that are twice as long as the previews in After Effects CC 2015.
- New Cache Before Playback option: If you enable this option, After Effects caches frames before starting playback. This behavior is similar to how RAM Preview behaved in past versions of After Effects. However, frames are not displayed to the Composition, Layer, or Footage panel as they are cached.
