Monitoring performance is super convenient in the Steam Deck, and the Gaming Mode’s overlay has multiple levels of information easily accessible to players. However, if you want to customize the Steam Deck performance overlay further, move around things, or even enable additional parameters, here is how you can do that.

Customizing the overlay used to involve editing the MangoHud configuration file manually, but it’s become very easy thanks to a plugin called MangoPeel for the Decky Loader. I’ll walk you through the steps to set it up.
