I already posted my problem nearly 1 year ago. I have a 16" MacBook Pro with a fully loaded M1 MAX processor, and 32GB of RAM. I am currently using Premiere pro 23.1.0 (build 86), on Ventura 13.2.
I work 90% of the time with an external display connected to my MacBook (LG UltraFine 27UL650-W) with a USBC-HDMI cable. So I work with two monitors.
My problem is that Premiere Pro is very very slow when editing, and it's not about playing the preview, but scrolling the timeline, moving clips on the timeline, moving a clip from one sequence to another... The UX is absolutely horrible, it feels like editing on an old PC with 1GB of RAM... I edit with low resolution proxies, and again: previewing is not the problem. I made a short screen recording to show you the problem. You can see that my mouse is smooth but when I interact with the software everything drops to 2-4fps...
When I unplug my external monitor, and restart PP, everything is fine, no problem, or less.
I don't know if the problem comes from Apple or Adobe, but in any case I'm pissed to see that a 4.000€ computer can't even run a software normally...
If you have any solutions for this, it would be awesome!
