Major lag on timeline with Premiere Pro v 23.1 - macOS

Based on our understanding of the problem I do not expect GPU driver updates to fix the issue. The main thing that initially made you think it was fixed was probably the relaunch of PPro. Closing and reopening the sequence only will also have the same effect. 

Hmm I have to take it back. One hour later and Premiere timeline is stuttering again andgetting less responsive

itam, thanks for posting your solution...  

I've had the same issue and have been looking everywhere for a fix. Only uninstalling and rolling back to 23.0 works! Will wait in the meantime to update. 

@John Tariot I really appreciate your words of thanks. We had people working over the weekend to fix this issue and I will be sure to pass it on to them. FYI we are this👌 close to having a permanent fix that we can put into a release version.

Hi Francis,

Beta is still exhibiting lagging/sluggish playback:

Adobe Premiere 23.3.0 Beta Build 24

macOS 12.6.3

iMac Pro

32 GB

Ultrastudio 4k Extreme 3

20TB Pegasus2-R RAID 20 Gb/s x1

Sequence settings (run smoothly in prior versions of Pr): 

24fps timebase

Video previews: 2048x1556 ProResHQ, LT, 4444 (and all others available)

Source files: 24fps 2048x1556 10-bit DPX

Have also tried setting audio input to none.

I will be rolling back to 23.0 or 22.6.x and hope things get back to normal.

Just a quick note of thanks to you too, Francis. Historically, my experience is that a direct response from Adobe here in the forums can be pretty rare. I realize that this is first and foremost a user-supported forum, and that Adobe can't engage with every user on every issue here. That said, I appreciate this clear update- and applaud any effort to stay in touch.

And EVERYONE is relieved to get validation of what we've all been seeing!

It's definitely an inconvenience.  If the issue that you are experiencing is Sequences under macOS not releasing RAM as expected, roll back to version 23.0 or use beta 23.3.

This is crushing my workflow. I'm testing out the beta option today but is there any update as to when this fix will be rolled out in an official shipped version?

Trying to be patient but this UI lag is unacceptable in a professional post-production environment. Especially for a program we're paying monthly for. Please fix this, Adobe. 

Thanks so much, @francis-crossman10980533. That's great news and I'm jumping onto the beta right now.
