Enhanced in After Effects CC 2015 | 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.

- Uninterrupted preview: You can now modify an open project while a preview is playing back in After Effects.
- Simplified and configurable preview: You can now customize Preview behaviors using the updated Preview panel. If you're new to After Effects, you can find the default Preview intuitive with real-time playback of cached frames. If you're an experienced After Effects user, you can use the Preview options that are configurable to suit your working style.
