- Installed and executed Steam on Linux Mint 22.1
- Proton Experimental (no extra commands)
- Game launch and run with no issues
Here is a game play sample https://youtu.be/eLhKB1Q2flo (PT-BR)
prime-run %command%
Does not launch with dGPU by default, use the command

Had to turn on fullscreen. Borderless fullscreen made problems with my mouse (clicks were a few pixels next to the cursor)
borderless fullscreen - mouse clicks were a few pixel next to the mouse cursor
Also the mods, compatible with 4.x, ran without any problems.

Everything working like a charm.
No problems so far, even in 4.0, maybe a bit more of lag than in 3.9 but thats something from the game and not linux as far as I know.
Works great out of the box

Can play vanilla completely fine. But playing modded maybe not.
Can play vanilla completely fine. But playing with any mod at all will just cause the game to crash when attempting to start a new game. And it happens with all mods no matter their load order or how many

env --unset=SDL_VIDEODRIVER --unset=ELECTRON_OZONE_PLATFORM_HINT %command%
If running on Wayland, and SDL_VIDEODRIVER
is set to wayland
and ELECTRON_OZONE_PLATFORM_HINT
is set to auto
, you might require unsetting them prior to launch to force Xwayland.
DRI_PRIME=1 gamemoderun mangohud %command%
Everything seems to be working fine except exiting the game opens a crash report but the save games are fine. Nothing to complain.

prime-run %command%
Game did not default to NVIDIA GPU.
Game runs at ~30FPS on integrated graphics but becomes unbearable towards the end.
As of a recent update, on Wayland machines it requires unsetting the `SDL_VIDEODRIVER` to force it to use Xwayland.
env --unset=SDL_VIDEODRIVER %command%

The game runs fine without mods without any tweaking. However, with mods, many mods appear to cause the game to crash. The reaso
LD_PRELOAD=/usr/lib/x86_64-linux-gnu/libjemalloc.so.2 bash -c 'exec "${@/dowser/stellaris}"' -- %command%
Certain mods without using LD_PRELOAD to load the game with JEMalloc will cause the game to crash while loading. The reasons for this are described here much better than I can explaint them: https://forum.paradoxplaza.com/forum/threads/stellaris-stellaris-on-linux-segmentation-faults-and-performance-3-14-68ca-without-mods.1726956/
To fix this issue, you must install JEMalloc, and point LD_PRELOAD to it, as I have done in my launch options.
LD_PRELOAD=/usr/lib/x86_64-linux-gnu/libjemalloc.so.2 bash -c 'exec "${@/dowser/stellaris}"' -- %command%
When loading mods, there is a documented issue as another described here: https://forum.paradoxplaza.com/forum/threads/stellaris-stellaris-on-linux-segmentation-faults-and-performance-3-14-68ca-without-mods.1726956/ Some mods will crash your game upon completion of loading, but this can be worked around by installing JEMalloc and using LD_PRELOAD to load this library with the game.

Crashes right after loading completes. Never reach the main menu.
Games launcher starts fine. Game begins loading and have audio. Loading progress reaches 100% and crashes. Error message is blank and error cannot be reported (maybe because of blank message).

LD_PRELOAD=/usr/lib/libjemalloc.so bash -c 'exec "${@/dowser/stellaris}"' -- %command%
Crashes consistently with segfault using certain mods
Crashes while using mods that change things related to ethics. Segfault when calling certain C functions. The suggested launch command will replace the memory allocator to a working one and skip the launcher as it wont start with the changed allocator.
Ethics and Civics Classic mod causes crash when loading main menu
Runs perfectly native and out-of-the-box. Mods included.

Launcher runs after dowser.exe workaround. Audio plays, but no game visuals.
eval $( echo "%command%" | sed 's/dowser.exe/stellaris.exe/g')
Arch Linux, Hyprland. HOI had a similar problem but actually runs when I hit play with the workaround.

It seems most mods actually do work
Mouse loading icon is frozen during startup
Aesthetic Cinematic Gameplay makes game get stuck on 100% load, Gigastructural engineering and planetary diversity mods work just fine.
I made a previous report where I said workshop mods were unsupported, that's just not true as it was one particular mod that caused issues (ACG)

It runs very smoothly compared to proton
Mouse loading icon animation is frozen during startup
Workshop mods just won't load in native game
Workshop mods won't work on native version even after trying different workarounds with the launcher and ironymodmanager, which is a massive shame
Working great so far, native. Stellaris version: Circinus V3.14.15926 (5377)

Works out of the box
Played it for 9 hours without Proton. Have not noticed any bugs but I have not tried any mods yet

Works out of the box
Runs natively without any apparent issues. I am currently 9 hours into my first Linux playthrough. Have not tried any mods yet though

modded games Freeze at 100% load
This is the second game that's "native" yet is unplayable, really starting to doubt the native tag

install dxvk so you dont need commandline arguments
Some people can play it natively, no idea why it does not work for me, it crashes without errors
The new patch broke the native version of the game for me, and textures are missing in the proton version
Screens flashing while game is open.

Install CryoUtilities
If you are getting crashes as soon as you jump into the game read this. I was in the exact same spot, tried Proton versions, tried starting commands, tried starting without internet, still same issue. Game would crash as soon as I would finish setting up the race and pressing play. I never got to see the game map. Until fixing something for another game (Crusader kings 3) where someone recommended installing CryoUtilities. This is the post I followed: https://www.reddit.com/r/SteamDeck/s/JvnwY7gJiN Simply install CryoUtilities with recommended settings: https://github.com/CryoByte33/steam-deck-utilities Now I can play, no other tinkering necessary on my side. Hope it works for you as well!

Worked out of the box.
Worked with mods online and offline on the newest version. Mods don't work on versions old 3.10 and below for a couple of versions.

-dx9
Crashes depending on specific mods installed. Ethics and Civics Classic required Experimental rather than default.

eval $( echo "%command%" | sed 's/dowser.exe/stellaris.exe/g') -dx9
Game needs to be run in dx9 or some textures are missing
I've had some issues with the paradox launcher, initialy it seemed to run fine but then it just stopped working. I've bypassed the launcher in the in the launch options and the game seems to run fine like that.

Works out of the box, both in single and multiplayer.
