Works perfectly out of the box.
It's turn based, so as long as you can get past the menu lag it's quite fun.
The game is generally playable at 30fps, but the menu chugs at 14. I easily get above 60fps on similar games.

No tinkering needed.
Stellaris Nexus 5X works flawlessly without any issues on SteamDeck (at least currently)
Nice short-session 4X experience working on SteamDeck out of the box, without any problems. 1 full game session takes about 1 hour and drains ~45% of battery with TDP at 10.
Could launch, but crashed before main menu.
Tried GE and EXP, with various launch commands.
Still fairly new, but doesn't work yet. More time in the oven could lead to fixes.
Crashed when hosting multiplayer game.
Stellaris Nexus playtest launched & played properly on a default Steam install on Linux Mint.
Wörks fine out of the box
Some text didnt match the button size, but that might be a localisation error, also the KDE mouse decoration did sometimes appear instead of the in game mouse, but maybe the textures are just missing since it is just a Beta.
Completed the tutorial without issues and could start a new Solo session.
