The Elder Scrolls Online is currently noted as Unsupported on Steam Deck but don’t let that stop you. Getting it running is actually pretty simple. I’m not surprised it’s noted as Unsupported though, considering how quirky the initial install actually is. You’re not just downloading from Steam, you’re also using their launcher to install an update and that is the main cause of the problems. A launcher being a nuisance — where have we all heard that before? First up a video example, below that is the text guide: How to do it: Find the game in your Steam Library, hit the little Cog icon on the right and go to Properties In the launch options text field, add this: PROTON_SET_GAME_DRIVE=1 %command% This basically sets up a fake drive in Proton for the game in your Steam Library that the launcher can read correctly Now set Steam Input to Mouse and Keyboard to make it easier for now with the updater and launcher Load it up, and when you get a black screen, simply press the A button.
