Manage Proton launch options easily on your Steam Deck via Decky Loader.
Decky Proton Launch provides a simple, intuitive interface to enable commonly used Proton environment variables for your Steam games. Select one or multiple options, copy the wrapper command, or configure per-game profiles directly from the plugin.
Click on any game to open its profile and configure launch options individually. Changes apply on next game launch.
When an option is enabled, you can instantly switch its value between Enable and Disable directly from the game profile.
The plugin automatically detects the currently running game and shows it at the top — click it to jump directly to its settings.
The settings view lets you choose the default home tab (variable list or game manager) and toggle the visibility of each variable category to keep only what's relevant to you.
When a new version is available, a banner appears at the top with a direct link to download it.
