Super slow playback in longer sequences
BUG: after pressing play, the timeline takes about 10-30 seconds to start playing, and becomes very choppy.
CPU & GPU usage very low during the 10-30 seconds.

Are you using a ton of clip based audio effects, or a ton of Essential Sound panel effects on your clips? There is a known issue when using lots of audio clip effects. Starting playback can take a long time.
The only workaround now is to attempt to convert the effects from clip effects to track based effects.
