From what I understand which isn’t much: Faugus gave me the impression it’s using that Debian based Steam runtime and makes it sound like Lutris, Bottles, etc don’t even if you’re using Proton. Does it matter? You tell me.
In practice I’ve not noticed any difference when I tested it out on a couple games to experiment. I don’t use Faugus because Gamescope doesn’t work yet according (last read a couple months ago) to their github page. If the old projects are dying then whatever. I’ll use Faugus Launcher when it’s actually ready.
I liked the GUI so far anyways so I won’t be upset if I have to switch.











I have almost none of those issues. CachyOS on two desktops. One is AMD CPU/Nvidia GPU, the other is Intel CPU/AMD GPU. Both KDE. I only use Steam native so far. 8bitdo Pro 2 controllers /w USB Wi-Fi 2.4Ghz dongles.
Occasionally a game hangs, but only about often as I had it happen on Windows.
The main problem I’m having is broken video playback on Store pages with their updated wide media player. Turns hardware acceleration on/off doesn’t fix it.
