GPU Acceleration (Mac) Suddenly Disabled - Rendering Times Killing Me

GPU acceleration has suddenly disappeared from Premiere Pro.

I've been looking through the threads and online but most responses seem to be for PC set ups and video card issues.

Can anyone shine some light on this issue and help as the rendering times are killing me!

First, have you checked the renderer setting in the general tab in the project settings?   Have you tried creating a new project and see if they correct option returns?  

 

Please tell us your system specs: OS version, Premiere version, amount of RAM, Hardware specs including graphics card

 

Have you done any recent OS or Premiere updates?  If so, reverting to the previous OS or Premiere version may be necessary

 

I strongly recommend that when you have a stable system, that you create a bootable clone of your startup drive using something like carbon copy cloner

and that you update it on a regular basis before you do any updates or install major software.  This way, if anything goes south or gets corrupted you can get back to work relatively quickly.

If Premiere Pro opens as M1 native (Apple Universal), then the Renderer is set to Metal and cannot be changed.  GPU acceleration for the parts of Premiere Pro that use it are always on.

 

 

If Premiere Pro opens using Rosetta, the Renderer can be set as Metal or Software only.  GPU acceleration for the parts of Premiere Pro that use it are only on if this is set to Metal.

 

 

 

 

As far as experiencing slower pefromace goes, have you tried looking at the Adobe Media Encoder log file for something you've exported with this setting on and something you've exported with this setting off?  In toubleshooting this issue, it might tbe worth exporting the same Sequence with each possible Renderer setting: Apple Universal Metal, Rosetta Metal, and Rosetta Soffware only.

    One thing to say here, legend

     

    Thanks for this post. 

     

    I haven't even tried looking at the Adobe Media Encoder Log fle but just the rendering within Premiere has changed. I had been looking at using different codecs and looking into this topic (as it's clear I don't really have a fundamental understanding of how the workflow really works and in the implications for choosing a codec or certain settings etc...).
