Handheld Companion Steam Deck
Create a profile once, then let Handheld Companion detect the active game and apply controller, motion, graphics and power preferences. Open QuickTools without leaving the game when you need a fast change.

Before you switch
This setup is for Windows 10 or Windows 11 installed on Steam Deck, not for the default SteamOS environment.
Install current Steam Deck Windows drivers before troubleshooting controller, audio, display or sensor behavior.
If Steam Input and another mapper both transform the same controls, simplify the chain until only one layer owns each mapping.
