Elin runs great without tinkering. I capped my framerate to 30 to improve battery life but this isn't required. The default controller layout is almost perfect and uses the trackpads for interacting in-game and quick switching the hotbar. My only note is that by default, the Deck triggers are swapped from the on-screen mouse cursor which can be disorientating when trying to interact, pick up, craft in-game (e.g., left trigger is mapped to right click, right trigger is mapped to left click). This is something that can be easily swapped in the Steam controller settings.
