I used mo2 from this installer https://github.com/rockerbacon/modorganizer2-linux-installer.
Both on Nvidia and AMD it’s been great. Older version had a bit laggy mo2, but now that is gone. Only issue I have is that ModOrganizer itself needs to be installed to main drive, otherwise it wouldn’t work, but maybe it’s also fixed now.
I didn’t learn anything. I was right all along.
