Steam

The popular game distribution platform and library management client from Valve.

NOTE: activate the multilib repository in /etc/pacman.conf to install Steam/Proton.

pacman -S steam

Where are my game saves for Proton-enabled games?

Games that are running via Steam Proton on Linux all use their own Wine prefix. The location of game data is here:

~/.steam/steam/steamapps/compatdata/[game ID]/pfx

You can look up a game's ID by accessing its properties in the steam client:

Right-click on the game Select "Properties..." Go to "Updates" Note down the "App ID"

Then navigate the directory structure in the drive_c/ subdirectory that replicates a Windows directory structure. Personal files are under the drive_c/users/steamuser/ directory.
