Valve might decide, that your favorite game runs better with Proton, than using the native Linux client.
If you don't want to use Proton, as recommended by Valve on your Steam Deck, you only have the choice of running the game using Steam Linux Runtime.
But you might have issues with that, so this compatibility-tool allows you to run your Linux-native games as is again.
