MacOS: Improve / FIX Multiple GPU Support in Premiere
Multiple GPUs in Premiere are technically supported, but they are not utilized properly.
Need a way to prioritize which GPU should be used "first" or a ranking method where you run an app/command and the software learns which one should be ranked first.
An iMac 27" (iMac19,1) with AMD Vega 48 dGPU and eGPU connected will utilize the eGPU when it is present.
However an AMD 5700 XT eGPU should only be a supplement since the internal Vega 48 is much better for hardware encoding on export, but it is barely utilized at all - less than 5-10% on GPU history report.
There's no way to say "USE THE VEGA 48 FOR ENCODE" or similar.
Times are literally 2-3x longer with eGPU connected for hardware encode. Often makes more sense to reboot machine without eGPU for exports.
