Proton Versions

Proton Versions

switch between Proton-Versions, automatically download custom Proton builds...

A specific Proton Version can be easily selected per game, by simply selecting one from an auto-generated dropdown Menu in the Game Menu.

The List of available Proton Versions is generated on the first stl launch (in /dev/shm) and recreated when a new Proton Version was added on the fly.

stl searches in the following sources for Proton Versions to generate the list:

• user installed compatibility tools (~/.steam/steam/compatibilitytools.d/)
• system-wide compatibility tools (/usr/share/steam/compatibilitytools.d)
• official proton versions installed via Steam in default SteamLibrary (~/.steam/steam/steamapps/common/)
• official proton versions installed via Steam in additional SteamLibrary Paths (the additional Paths are extraced from ~/.steam/steam/config/config.vdf)
• a custom Proton List

Custom Proton List

The optional custom Proton List CUSTOMPROTONLIST in STLCFGDIR is used as additional source for custom Proton Versions for inclusion into the auto-generated Proton Version (dropdown) List.

Adding Entries to the Custom Proton List

There are several methods to add new entries to the list (besides editing it manually / via Editor Menu):

Adding local Custom Proton

a locally installed Custom Proton can be added

• via Command Line: stl addcustomproton or just stl acp (accepting an absolute path to a proton executable as optional argument)

A proton file can be selected via file-requester and an optional "proton version name" can be entered in a separate field.

Automatic Proton version

Using the variable WANTPROTON in configs and tweaks it is possible to automatically request a specific proton version to be used with the corresponding game. If AUTOPULLPROTON is enabled (it is by default) stl will automatically download the specific proton version and install it.
