Same here and with an Optimus configuration ( NVIDIA + Intel GPU ). Work flawlessly on my Fedora.

Comet support achievements and are already usable with Heroic if you launch it yourself.

Cloud saves are already supported by Heroic ; Comet can already be used if you launch it yourself but will be integrated in the package in the future. Comet support online features and achievements. Heroic + Comet = Gog Galaxy

I use Heroic for installation, updates and cloud saves, and Comet for online and achievements functionnalities, no need for Galaxy via wine anymore.

Minetest with mineclonia ; Dead Cells ; 0A.D. with my childrens ; Grim Dawn with Reign of Terror mod and Zombasite

my favorite daw is renoise. The sample management is excellent (it’s a tracker) and it manages VST perfectly well.
