Works great out of the box
Multiplayer has worked perfectly so far. I got no complaints.

Just works like native
No tinkering needed here, I played with all the default settings, launched the game and it works a treat.

no problems except left joystick locked up on camera pan, fixed by hitting steam menu and going back to game
framerate drops with graphics set too high on deck, bring down to suit preference.
ok but no multiplayer (yet)
really nice

It crashed once after 5 hours while hovering things in the Elder hall
Crashes occur freqently enough, and performance is pretty bad, even on RTX3070ti
Can confirm that. Downloaded the vc_redist.x86.exe and renamed it according to the fix on https://github.com/ValveSoftware/Proton/issues/4138#issuecomment-850575335. Works fine except that it installs the vc-redist.exe every time I launch the game. But works fine.

And it runs =)

The game complains that DX12 is not supported by the system, so I added a Launch flag: "-dx11"
