Final Cut Pro users:
- If you have 2 AMD GPUs, how can Final Cut Pro recognize and use both?
https://www.tonymacx86.com/threads/...olt-3-i7-9700k-amd-rx-580.267551/post-2246182 This is what I've been trying to discover.
I think I misunderstood some of what I read, haha. It seems the radeon vii's use amd's infinity link, with support up to 4 GPU's. I didn't realize it was unique to Radeon VII's/GPU's with infinity link. Evidently in a recent update of final cute, it brought support for that in Mac Pro's.
So that was what I was thinking, but doesn't appear it works for other AMD GPU's.
There are miscellaneous anecdotes from Final Cut users that I've see recently that have 2 matching GPU's. They claim Final Cut is spreading the load across them, while allowing them to select one of multiple GPU's specifically for rendering.
I mainly use Premier Pro. So I thought I could get a leg up by trying out multi GPU in Final Cut.
I believe with Premier and Media Encoder, though, multiple GPU's can be used for export rendering. It also appears there are some other software suites that are built for multi-acceleration. I am curious to give that a try.
Seems I misunderstood the problem. Both AMD GPUs should automatically appear in System Information --> PCI. Also check if they both appear in IORegistryExplorer (look for AMD9500Controller).
For some reason, only one shows up in both places. I made sure I didn't have the disable GPU in PCI-e 2 slot. But I do have (always have had) your SSDT for AMD Radeon RX580 in my EFI. I can't quite remember what it does. Could that be keeping it from seeing the second GPU?
I also have some custom output from hackintool when I switched my config over to headless mode. Not sure if that could be messing with it too.
