Improve Timeline Performance - 2019 MBP 16"

Hey All,

 

I am getting very poor timeline performance with my new laptop, and am unsure of the cause.

2019 16" MBP, 6-core i7, 16GB RAM, 5300M, 512GB SSD

 

I'm doing some really simple stuff, just cutting and overlaying 2x 1080p clips on top of one another. But even in the Source monitor, I am getting really bad playback performance. Dropped frames indicator is yellow half the time. There is a several second delay between hitting spacebar, and the video playing. All files are stored locally, I even tried generating proxies, but no matter what playback seems buggy. The play/pause dealy is the main issue. Running 14.0.0 Build 572. Any tips and advice is appreciated!

Ok, 

After a suprisingly short amount of additional digging, some preliminary results.

 

1. Using Apple ProRes Proxies does improve it, GoPro CineForm does not

2. Switching from Metal to OpenCL essentailly fixes the issue. 

 

So it appears that this is just a problem with the new Metal Renderer. Should have figured that out sooner. Will be switching back to OpenCL for a little bit until this is resolved, it's silly to be using proxies on 1080p footage.

I've been having the same issue on my imac with 128 RAM, 120 RAM dedicated to premiere while using it. Spacebar experiences a 2-second delay, occasionally, when I try to play and pause. Has anything besides switching to Open CL worked since last year?

I am sorry to tell you this, but you're actually choking off the performance of your iMac Pro: You have way too much of that RAM dedicated to Premiere, leaving only 8 GB of RAM for the rest of your system whenever Premiere Pro is running. You should ideally have only about 100 GB of RAM dedicated to Premiere, leaving about 28 GB of RAM free for other apps and the OS.
