Lutris is an all-in-one open source game manager for launching games from various stores on Linux, with version 0.5.20 out now.
This release overhauls how it runs GE-Proton, making use of the modern umu launcher to keep it all running nicely. So it should, in theory, offer a better experience than before when running Windows games. It also improves support for Wayland, adds support for the ZOOM Platform store, there’s improvements for the EA App, some settings have been cleaned up and much more.
GOG have historically been Linux haters. With the recent change in ownership, it seems that might be changing, and if true it means the ones who were anti-Linux were probably CDPR rather than the GOG team.
In any case, GOG games work well through Lutris for me, but there’s also Heroic as an alternative.
