This is useful

But the explanation from Michael Kefeder helped me a lot. I was
misunderstanding the documentation initially.
I have a spare rx 470 4GB which could be used for the purpose.
Remembering that the second PCIe-x16 slot only runs in x4 modus with
Ryzen CPU's.
Benchmarks and performance stats are welcome.
Under windows - GPU Intel UHD Graphics 630 and NVIDIA Quadro P1000 -
never gets utilized to max. I can observe utilization about 30-40%
(windows task manager) even on export and using local SSD drive for all
images. I don't know if this is what is "expected".
