I might be misunderstanding but isn’t that a function of steam itself? Not a custom OS? And game mode is just big picture mode?

Game mode is way better than big picture because

support for decky loader

control system level settings from game mode itself

has gamescope which handles win32 game settings much better

disables other OS processes/the desktop and frees up resources (not sure about this)

control more things with controller instead of the touchscreen

No, game mode is a specific mode made for the Steam Deck and other portables. I believe people have also gotten it to work on the ROG Ally. It replaces the desktop entirely while active, and only Steam games, and games that are added as a shortcut to Steam can be launched. It is not something that is launched from Steam like Big Picture mode, and while it is active, there is no desktop, and no other way to interact with the Deck. Using the desktop normally requires exiting game mode entirely.
