Question: MacOS preferred GPU
Hi! Hoping someone can help me out. I'm running an iMac Pro with a Vega 64 16GB. I want to use my Mantiz Venus with RX 580 to drive an HDMI client TV as well as a two 4k dell displays for bins and full preview at my desk.
My problem is Adobe Premiere Pro 2019 seems to be preferring to use the eGPU RX 580 during playback and encode. It's not configured to use the eGPU in 'Get Info'. I've tried launching the program with no components displaying anywhere but the iMac screen (and Mercury off), but GPU history shows it's still using the RX 580 for playback opposed to my Vega (which is what I want). Any thoughts on how to force the app to use my discreet Vega card?
That was one of my first thoughts as well, it's set to the iMac screen. Can't seem to figure this one out. Most people have trouble getting adobe to use eGPU and I want it the other way around lol. Any other thoughts?
Yeah that's weird. My only other idea would be to start it without the egpu connected and then plug in the egpu only once its running. I haven't used premere or anything but I assume it's doing something weird
I may have figured this out. It looks like Adobe has enhanced multi GPU support (finally) for Adobe Premiere Pro in 2019.

While this doesn't fully explain why Pr isn't utilizing my dGPU Vega 64, I suppose this makes sense. A shame they don't have any preference settings (similar to their audio hardware panel) or, include functionality similar to Davinci Resolve's superior GPU settings panel.
I can kind of understand that (speaking as a graphics developer). Typically you just have a box with one or more GPUs, and you select the fastest available one to use. Which is already difficult, because there’s no easy way to know which is fastest… and you might have 3, and the slowest at one task will be fastest at another.
