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
 
 Manage Steam compatibility tools 
 Apart from Valve's Proton distribution, there are other compatibility tools available with patches and performance improvements for games. 
 ProtonUp-Qt is a graphical utility to manage many different compatibility tools, not only for Steam but also other launchers like Heroic Games Launcher. 
 It's available from the AUR: 
 yay -S protonup-qt
 
 Another management tool that integrates with the look & feel of the GNOME desktop is ProtonPlus , also available in the AUR: 
 yay -S protonplus
 
 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.
