Mercury playback engine gpu acceleration greyed out

[joejugs]

I have the brand new macbook pro max fully upgraded. My project for some reason recently has just been super laggy. ill open it up & then when i skim through the timeline all of a sudden the playback will freeze. I have all other funcitons in premeire but the playback on the computer wont work. Im trying to see if i can change the Render & Playback settings but its greyed out i cant figure out why. Ive tried opening a new project but its the same thing.

That setting is enabled by default if running Premiere Pro as Apple silicon native.

While Premiere Pro is closed, get into on the application in the Finder and enable "Open using Rosetta".  You'll then be able to change that project setting.

What??? Could you be a little more specific?

Specifically, when you open Premiere Pro normally, it runs in Apple Silicon native mode by default, and it's renderer is permanently locked into the Metal GPU acceleration mode. You will need to open the Creative Cloud desktop app, then click on the Apps tab, then click on the three dots next to the Premiere Pro line, then click Open in Intel mode. Unfortunately, the only other renderer setting besides Metal that's available is Software Only.
