ProtonUp-Qt is an essential tool to help you install and manage GE-Proton, Luxtorpeda, Wine-GE and more for Steam, Heroic and Lutris for Linux desktop and Steam Deck.

But why would you need it? Well, sometimes Valve's official Proton doesn't work well with a game, so you need GE-Proton. If you want to easily play third-party upgraded game engines for some classic Steam games like OpenMW for Morrowind or OpenXcom for X-COM and so on (see my previous article) you can use Luxtorpeda and so on.

Version 2.9.1 was just released and here's what's new:

    Added a Shortcut Editor for Steam.
    Dxvk-Async: Use Ph42oN's releases instead of Sporif's.
    NorthstarProton: Use the R2NorthstarTools repo instead of the cyrv6737 repo.
    Wine-GE: Match extract folder name (see PR #296 for details).
    Allow configuring GitHub/GitLab access tokens in the ProtonUp-Qt configuration file (see #161 (comment)).
    Various i18n, UI and UX enhancements.
