I would really like to ditch Steam in favour of a native GTK application which integrates better with my system and which is also libre software.
Does anyone know how well it works? Can I truly replace the Steam client with this or does it still have a lot of lacking features?
Any games you already own on Steam or Epic will still need to launch those clients in order to run with GameHub. If you run Linux, then a lot of the work Steam does in the background with Proton to make things run will no longer be automatic.
