Star Realms on Steam Linux

It was simpler than I thought to get Star Realms running on Linux.

First up, we need to enable Steam Play for unsupported titles. This can be done in two ways:

Just for Star Realms or For all Steam Apps

Just for Star Realms

From the Star Realms library page, open up the cog menu and pick properties:

From there, enable "Force the use of a specific Steam Play compatibility tool" and select Proton as the engine (3, 4 and 5 have all worked for me):

You should now be able to install and start Star Realms.

If it crashes on startup, you may need to tweak the Proton settings, see below.

For all Steam Apps

From the main Steam menu, pick settings:

Head to the Steam Play section on the left, checked "Enable Steam Play for supported titles" and "Enable Steam Play for all other titles" and se "Run other titles with" to Proton:

Select OK and Steam will restart. Head to the Star Realms library page and you should now be able to install and run Star Realms.

If it crashes on startup, you may need to tweak the Proton settings, see below.

Crashes on Startup

On my laptop, Proton crashes on startup. To get around this, I needed to tweak the Proton configuration.  To find the setting that work, from the Star Realms library page, open up the cog menu and pick properties:

From there, head in to the "Set Launch Options" dialog:

Here you can override the default Proton configuration. There is a list of available settings in:

~/.steam/steam/steamapps/common/Proton 5.0/user_settings.sample.py.

The setting I needed was:

PROTON_USE_WINED3D11=1

This can be passed as:

Once you've found which settings work, you can rename user_settings.sample.py to user_settings.py and then edit it so your settings are global:

Once this is done, you can remove the Star Realms specific settings.
