Missing from Steam’s Compatibility Tool List:

This issue often arises due to incorrect installation or integration problems with Steam. Here’s what you can do:

    • Ensure Proper Installation: Verify that Proton GE is correctly installed on your system. You can download it from trusted sources or repositories like GitHub.
    • Steam Library Configuration: Navigate to Steam’s settings, then go to the “Steam Play” section. Check if the option “Enable Steam Play for all other titles” is selected. If not, enable it.
    • Verify Proton GE Integration: Open Steam and navigate to the “Steam” menu, then select “Settings” followed by “Steam Play.” Ensure that Proton GE appears in the compatibility tool list. If not, restart Steam or try reinstalling Proton GE.

Inability to Select Proton GE for Games:

If Proton GE is missing from the dropdown menu when configuring a game, try these steps:

    • Refresh Steam: Sometimes, Steam may not detect newly installed Proton versions immediately. Restart Steam to refresh the compatibility tool list.
    • Manually Add Proton GE: If Proton GE still doesn’t appear, you can manually add it to Steam’s compatibility tool list. Navigate to Steam’s installation directory, then locate the “compatibilitytools.d” folder. Copy the Proton GE files into this directory, restart Steam, and check if it’s now available for selection.
    • Update Steam: Ensure that your Steam client is up-to-date. Outdated versions may encounter compatibility issues with newer Proton releases.
