There's not a lot to learn, desktop Linux is pretty much the same as windows was when it was still good.
I've only been using Linux for 20 years so can you explain what you mean by this?
So, no, "no problems" is a bit of overselling it.
But the original point wasn't whether Linux could, but whether it's different from Windows.
And as someone who compiles DXVK from git: dx12 won't work out of the box; it is different from Windows. Not particularly difficult, but different...
