One True Linux Thread™

Success! (sort of).
With potato config by @The Real Snake and in Labwc with no other GPU-using apps running KSA starts successfully!

10 FPS, no planets or stars visible, just the HUD and vessels with all the plume effects.

4GB seems to be the magic number on this iGPU.

@Crasher_Chunk asked in another thread:

How did you get kitten space agency to install on linux? Did you make a custom installer?

I'll answer here to not hijack the other thread:

I used Lutris. Add Proton or wine under settings/starter/wine (the symbol to the right of 'wine').
Then select the plus sign on the top left of the main window. 'Install Windows game from an executable'. Add a name for the new game (Kitten Space Agency comes to mind), select a location to install to and then select the downloaded KSA installer.
Select the installed game, on the bottom next to 'Play game' there is another symbol, click it and select 'Winetricks'. In winetricks select 'standard prefix', 'Install windows-dll', 'dotnetdesktop9'.
Then try to start the game. For me it worked flawless. I reduced some texture sizes and most settings to medium to reduce stress on the gpu. But it also worked on max settings. There were no texture errors and no crashes yet (several landings on earth and moon).

Early days yet, but running very nicely at 4k. Like others have said, I had to install dot net. Sometimes on load. I seem to go to full screen at 1080 or something, but usually changing screen mode fixes that. It'll be lovely to have this in Bazaar and Steam as a native app, although I've no idea how possible it will be.

Arch	Ryzen 9 7950X3D	RTX 4090	Wayland, Hyprland	Steam (proton-ge)	install dotnet9desktop with protontricks

Works pretty well do have some stability issues if I try to move the window or leave fullscreen the performance dies. I also tried using

PROTON_ENABLE_WAYLAND=1

which did work just instead of the performance lowering when I tried to move the window it would now instead hard crash.

a5000m, i9 11th gen, got it to run on steam as a non-steam game on Proton experimental.

A solid 20-25 fps.

With that install it won't have the required windows deps (https://dotnet.microsoft.com/en-us/....0.11-windows-x64-installer?cid=getdotnetcore) , so itll make you download and install that as well, do that by changing the target on the non-steam game so it ends up in the proper prefix with it, then switch to the executable that's buried like 15 layers deep via steamapps/common/blah

Im using x11 and not wayland.

New update giving a solid 20-25 still.

I figured why I couldn't make it work in Lutris... I had this problem where game complained about missing .net despite the fact I installed it in the prefix. It turns out that I had Linux .net installed, and the exported DOTNET_ROOT broke everything (╯°□°)╯︵ ┻━┻

Yeah, env vars affecting windows apps in wine is a huge gotcha. Got bitten by SDL_VIDEODRIVER in another game (was among other wayland-related vars in my usual environment).

Followed "Jov's Gaming Lounge" succinct YouTube video on "Installing Games on Linux With Lutris" to get my Lutris and Wine install correct (make sure you finish the WineHQ install before you install Lutris).

Downloaded the KSA script from Lutris.net.

Edited the YAML script's dotnet9 entry to dotnetdesktop9 (as stipulated in Heightmare's Discord video).

Downloaded the setup_ksa_v*.exe

Install KSA:

Lutris > Add Game > Install from a local install script. Follow the instructions - apparently, any error(s) can be ignored.

Update KSA:

Download new setup_ksa_v*.exe

Move the existing KSA folder (backup):

mv "/path/to/Prefix/Directory/drive_c/Program Files/Kitten Space Agency" \
"/path/to/Prefix/Directory/drive_c/Program Files/KSA_old"

Run KSA's setup.exe with Wine inside the existing prefix.

WINEPREFIX="/path/to/KSA/Prefix/Directory" wine /path/to/setup_ksa_v*.exe

You can check this wiki for installing via Steam/Proton: https://kittenspaceagency.wiki.gg/wiki/Help:Installing_on_Linux_via_Steam_Proton

I installed KSA on debian trixie like this:

Download the installer from https://ahwoo.com/store/KPbAA1Au/kitten-space-agency , e.g.
setup_ksa_v2025.11.8.2847.exe (1.5 GB)
apt install lutris (as root or with sudo)
Start lutris. Wait till it's done downloading/installing some things.
On https://lutris.net/games/kitten-space-agency/ click install (maybe check the script for malware first)
select the installer (setup_ksa_v2025.11.8.2847.exe) e.g. from your Downloads directory. Click install.
play

I only got 5 FPS (you can get the FPS display in the game with F1). I tried lots of settings suggested by gpt5, Compatibility layers (wine-ge-8-26, Proton 9 (beta), Proton experimental, Wine-10.16-staging-amd64-wow64), nothing helped. When I read others had low FPS, too, I gave up.

I had the same problem with 2025.11.5.2897. Low FPS (5fps). The previous version was rock solid and no lag at all.

My GPU was reporting 100% utilization, but no fan ramp up, no temperature increase, and no increased heat coming out of the computer.

Disabling the ocean in graphical settings fixed it for me, back at decent FPS and the GPU now reports 68% utilization (I have my FPS capped at 30) and there is indeed heat coming out of the computer now.
