Runs straight out of the box, without any issues
Proton Experimental with no extra tinkering does not run the game at all. ("Failed to initialize player: [...] InitializeGraphicsEngine failed.") The following versions seem to work fine except for the initial audio stuttering: Proton 7.0, Proton 6.3. The following older versions seem to work fine except for the initial video, which is replaced by silence and a black screen: Proton 5.13, Proton 4.11.
now works ok, use to have problems
haven't played longer recently, check for slow turns in late game

Since v1.2, the game runs well under proton.
The intro movie is not working all the time. But it can be disabled in the settings.
as turns became very long later, experience will not be best
since latest patch, planet detail screen is missing, it is white, but does not influence gameplay as it is cosmetic only
slow turns and slow loading times
I had to choose the 'linuxtest' beta to install the game. The default setting (opt-out of all betas) results in an empty download (0k). Changing the setting back to 'NONE' removes the game files.


Runs perfectly in and of itself, but if you alt+tab out of the application and back the screen becomes a very tiny box in the top right, I haven't been able to resolve this yet.


The long load time is gone (may have been first launch). The new 1.0.4 patch continues to work well. No issues at all.

Despite a long load at launch (black screen for ~45 seconds), the game runs perfectly. Maximum graphics settings, no slow downs or crashes.

Runs out of the box without any tweaks required but framerate is rather low, around 15 fps in some screens. However as this is turn based game it didn't really impact my experience all that much.
