Coming to Premiere Pro (Beta) is significantly improved performance when playing back sequences containing a high number of audio clip effects.  Previously, Premiere would pre-calculate audio effect information for the entire sequence duration, which depending on the complexity of the sequence, could take several seconds between pressing Play and having the playhead start moving.  Now, Premiere calculates only the minimum required for playback to begin and remain consistent.

 

In one of our test projects, a 1.7TB sequence with 1000's of clips and audio clip effects, these changes brought our average latency starting playback from 13.2 seconds to 81 milliseconds - a 164x improvement!  Your mileage will vary, of course, but expect to see dramatic improvements and practically imperceptible delays when previewing and playing sequences like this.

Happy to revive this thread as the feature is FINALLY being unlocked for Public Beta this week.  While I've mentioned a 164x improvement, it's technically infinte as the complexity of the full sequence is irrelevant to playback starting.  While there are certainly other factors that can impact playback performance, the audio clip effects should no longer be one of them.  This is a DRASTIC improvement in overall responsiveness and the team is very, very happy with the results.
