When you say Battlefront 2 do you mean the modern one or the old PS2 one? The old one is pretty nice on deck but be prepared to dial in your stick / trackpad sensitivity. It doesn’t take well to playing on a joypad. Just some teething problems.

Huh, am I misremembering something? I was under the impression this update brought a function to update flatpaks / Discover store programs while still in Gaming Mode.
