Premiere Pro not using eGPU to accelerate supported effects

Hello experts,

Setup:

  • I have a Radeon Vega 64 GPU in a Razer Core X enclosure on a 2019 iMac.
    I am edting 360º footage using all Adobe approved acceleration-supported effects.
  • I have "prefer external GPU" checkbox in get info window for Primere Pro 2020 and Media Encoder 2019.
  • When rendering I am using "Mercury playback engine GPU accelration (Metal)"

Problem:

  • When I render out of Premiere/Media Encoder I expect support from the from the eGPU. However,  checking Activity monitor for the GPU history the eGPU is not being engaged.
  • On some screens I even have the message "GPU acceleration needed" 
  • When I scrub I can see a small percentage of activity on the activity monitor for the card.
  • When exporting there is no activity at all. 
  • Tests so far
    I have tested with other software which uses the eGPU perfectly (so the problem is not with the eGPU setup)
  • I have tested using Mac OS Mojave and Catalina, same issue in both (so the problem is not with Mac OS)
  • I have tested in Premiere Pro and Media Encoder (so the problem is not a single piece of software)
  • I have tested scrubbing effects as well as rendering (so it is not a single activity)
  • I tried "Mercury playback engine GPU accelration (Metal)" and "Mercury playback engine GPU accelration (Open CL)" (so it is not a single render engine)

 

Please advise.

Which effects are you using on the sequences you've tested?

I have used:
- VR plane to sphere
- VR projection
- a few Lumetri effects for colour correction

I can add a little more color to this discussion, but no answer (I'm interested also).

 

 

I notice that when I use metal encoding with PR, my built in discreet processor (Radeon Pro 5500M) is full engaged and the EGPU RX Vega 56 in BlackMagic Pro is practically idle. (see attached).

 

When I run Geekbench 5 (https://www.geekbench.com/download/mac/), I get the same results they do. That is, when I select to test "metal" performance on the EGPU, I get twice the performance as when I run it on the . build in 5500 graphics.

 

https://browser.geekbench.com/metal-benchmarks

 

I notice that there are some old notes around that talk about how to "select preferred graphics" for processing on a mac, but that does not seem to work on on the current OSX version.

Premiere CC 2019 had no issues w/ my Radeon VII in a Razer eGPU enclosure. I was easily rendering 10-20 min videos in 1080p in less than 10 minutes, even with lots of effects. Premiere CC 2020 and Media Encoder now max out the internal GPU of my MBP (Radeon Pro 560X) and don't touch the eGPU at all. (Yes, I have the "prefer eGPU box" ticked.)  1080p videos now take over an hour to render, even if there's nothing more complex than a key on them.

Adobe is just failing with EGPU.  Latest MacBook Pro 16, current and only EGPU Apple sells.  Makes no sense that built in egpu works hard and external is idle.
