If you want your game to look more sharp/crisp, in the Steam Properties, set the Resolution to 1920x1200 and Check Set for Internal /External, Basically the deck will render Yuzu way higher, Making the game being rendered look super sharp/crisp and it won’t affect the performance. Make sure you don’t have Anti-Aliasing on.
