I still want use the native libraries, so I installed steam-native-runtime from the AUR. I’m not sure if it actually makes a difference if I use steam or steam-native, especially if I use proton-cachyos
It would be nice if the cachyos repo kept building these packages from the AUR, at least the dependencies for steam-native, it already has a lot of AUR packages, most of the time it just repackages binary packages, which makes no difference for the installed program.
