In a Player view or in the fullscreen Player, you can set a Player preference that determines whether real-time playback has priority over a playback that includes every frame or vice-versa. Real-time playback is also influenced by the hardware on which you are running Composite, and the load on that machine at the time you perform the playback.
To set real-time playback preferences:
Play All Frames Select this button to play every frame, regardless of the impact on real-time playback. Deselect to have the Player view drop frames if necessary to perform playback as close to real-time as possible.
