I am freaking out on how well distrobox is working for me. I buy a lot of games on itch.io and GOG, and neither have a flatpak. However, installing an Ubuntu container (max compatibility) and launching games from there just works. Okay, I have yet to install a GOG game, but it the Itch client works then what won’t?
I am so excited. Containers are so fun. I guess arch would be easier, but whatevs.
Concerning Baldur’s Gate, are you using Wayland or X11? For me Wayland was much smoother than X11.
I think I am using Wayland since that is the default.
Also, I once made the mistake of running on DX11, which was worse.
