works great, without probmes.
Steam selected “Proton Experimental” by Defualt. The game starts, cutscenes are played and I have already played up to mission 9 of the main campain without any problems. But I haven't had a chance to test the co-op yet.

Works like a charm, except the very rare and short cutscenes stuttering.
Stutters in Cutscenes

Starting a map is mostly black screen.
Was able to start game and see main menu, but the background scene's graphics are obscured by a random stretched out texture over the entire screen. Starting a map results in the terrain and NPCs being underneath a black shader/missing texture, with only the UI and a few 3d objects rendered correctly (large objects that sit higher above the terrain).

No problem
Runs like a charm on my end

Works on Steam Deck, borked on Desktop?
Kalypso launcher doesn't seem to cause any issues, game loads to main menu with no issues, intro cutscene for the first campaign mission works, however once the gameplay starts, the game world does not render properly.
Tried Proton Experimental and multiple older versions on Desktop, none seemed to resolve the issue.
Interestingly, the issue is not present on Steam Deck.

Had a few stutters on cutscenes that were not present on windows. Also less FPS than on windows but still perfectly playable.
Played the first half of the campaign on windows and the rest on my fresh Arch install. No gamebreaking problems. Maybe some tinkering can improve performance, but i played it with default settings an it was good enough for me.
can rarely crash something related to multimedia codecs which requires restarting if you want to watch or listen to videos etc.

No issues
I've only played through the first bit of the campaign so far (~95 minutes), but I've had zero issues. Really enjoying the game.

Issues on external Controller; Had to move the right analog stick to be able to move the cursor with the left analog stick, like the cursor was "sticky". Surely not an intended behaviour
Note: This is about the Dungeons 4 DEMO, not the full game
