This is the best summary I could come up with:
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.
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.
Wine-GE: Match extract folder name (see PR #296 for details).
It's available on Flathub or using your favourite app store (like Discover on KDE Plasma / Steam Deck Destop Mode).
Mark the AppImage as executable (either using your file manager or using the Terminal: chmod +x ProtonUp-Qt*.AppImage).
