The Steam dock is great but there are some great ones for cheaper.
Software to install:
CryoUtilities: It changes a few things to give some performance increases. It’s debatable whether they’re noticeable. One thing you can change yourself in the BIOS is changing the available VRAM from 1GB to 4GB.
Decky Loader: This gives you quick access to all kinds of things. A must install. ProtonDB will add badges to game pages to tell you how well they run under proton even if they’re not Steam verified. SteamGridDB will let you change art for games and apps you install.
Heroic Game Launcher: This is the easiest way to add games you own from Epic, GOG, and Amazon.
ProtonUp-Qt: Install custom versions of Proton that can improve performance. I think there’s something in Decky Loader that will do this as well but I haven’t tried it.
That’ll get you started.
