Can confirm. Discovering out how well Valheim runs on steam deck basically killed my productivity entirely when the Mistlands update came out.

Yes, but you can't join crossplay-enabled servers with the Linux binary.

That sucks, we hosted it on AWS and it was fine but it was just Windows and Linux clients.

Consoles/PC gamepass. It doesn't really matter either way, once you run it in Proton with Vulkan there's almost no performance hit.
