Mouse and keyboard is recommended
Reduce atlas resolution to medium and below for good FPS

Recommended to use with keyboard and mouse in Desktop Mode
Need to lower atlas quality to medium or lower to get decent fps
Struggled with recent update and would not boot. Booted through Lutris but game wouldn't allow further playing due to not being ran through Steam. Lowered from Proton Experimental to Proton 8.0-5 and runs fine now!

No audio
There is no sound but the game otherwise works fine

PROTON_USE_WINED3D=1 %command%
launch command only use for older hardware

Install it on a drive a with a proper label and a permanent mount point. In my case mnt/hdd
Didn't use to work because I had it installed on my external hard drive without a permanent mount point and without a label on the hard drive. After making the mount point permanent and having a shorter mount address it worked perfectly.
If getting a black screen upon launching the game in Flatpak Steam, try to create a new drive in Settings -> Storage
and install/move the game there. I've used /home/***username***/.steam
.
It works because with the default drive (/home/***username***/.var/app/com.valvesoftware.Steam/data/Steam
) some game files' path exceed the maximum (254).
You might need to grant access to the new folder via flatpak CLI or Flatseal.

Opens but doesn't work
Attempted using GE and every Proton version Steam comes with
Used every version of Proton Steam comes with, it just opens a black window. Got close with Proton 6 but it says I don't meet minimum specs (I meet recomended specs)

Game launches a window and it is black, nothing happens, and no audio either
I have tried multiple versions of Proton including the latest couple Glorious Eggroll ones but none of them helped run the game.

Performance issue not correlated with hardware
Fix: In the in-game settings look for "Surface Simulation" and set "All Maps Atlas Resolution" to 512x1024. This will grant you a good boost but you still might experience some performance problem when there is too much "chaos".
On windows I am able to play at maximum graphic (not simulation) settings with a steady 200 fps meanwhile on Linux I barely get 60 and they drop frequently.

Vr functional
I love blowing up planets

ge proton 9.11 just works
Actually runs better than on Windows.

Low FPS
Open performance settings from the in-game setting menu. Look for "Surface Simulation" change "All Maps Atlas Resolution" to 512x1024

runnung the game to fast and using the explosion tool (to many debris) caused my computer to crash
the game uses/need on linux more "computer power" as in Windows, to do the same. for example: exploding a planet
With a good PC and if you don't exaggerate it works well.

They dropped the Linux native build and performance got worse over the years.
Very subpar performance compared to 1-2 years ago. Even when you reach a stable framerate during normal gameplay, it drops significantly when opening a planet/star/etc's menu.
Besides the performance degradation over the game's updates, you also have even worse performance because of Proton's performance overhead that is more noticeable on bloated/less efficient games. There used to be a great Linux native build before, but they decided to drop it.

Some text very hard to read.
Runs like garbage no matter the GFX settings. Simply not a smooth or remotely enjoyable performance level.

Game freezes on loading screen

Wish they hadn't removed Linux support :(

Native client works well. If you like creating and destroying planets this is your game!
Good overall but the native seems to have some weird math problem where it'll just show insane numbers. Apart from that its fully playable

Some text in menus is extremely small. While legible if you have excellent eyesight, you'll want to use the magnifier to avoid straining your eyes.
It was a nice surprise to find Universe Sandbox not only playable on the Deck, but enjoyable as well. A bit of a battery hog, but the Deck is more than capable of running this title.
- Default graphics settings works well. GUI renders at native res but sandbox render is downsampled. YMMV with sandbox render at native res.
- Text can be hard to read in certain places. You'll want to make use of the magnifier if you're struggling to read the properties of objects.
- Quite the battery drain. Would not recommend playing on a long haul.
- Smoothest experience when locking framerate to 30 fps in Steam's performance settings.
The game pops up a warning saying there's not enough vram, but plays flawlessly.
Runs perfectly fine with a good FPS boost.
Runs great without any configuration
Runs perfectly with Proton, better than native. Performance seems to be superior than on Windows

Great experience overall.
Native version was unplayable due to broken features (wrong in-game calculations, missing textures, bugs) but running the game with Proton fixed all issues. No discernable performance difference between versions.
Worked perfectly, no tweaks proton 5.13-1

As VR does not work in native, i tried proton. The game runs, VR works, but sound stops after loading and performance is not that great.
It did eventually show a window, but it took a long time and it was running very slow. Additionally, it did not detect my Vive.
