Final Fantasy XIV Steam Deck Install Guide
The Steam Deck allows the ability to play massive MMORPGs like Final Fantasy XIV on a handheld device. With some tweaking, you can run the game smoothly and play on on-the-go. One note, the Final Fantasy Trial download doesn't work for existing accounts, and the Steam Version is a different license from the FF14 launcher version, so you won't be able to use an existing account if you'd like to download from Steam.
Follow the steps below to get the Final Fantasy XIV launcher installed, configured, and optimized for your Steam Deck or watch the video for a full visual tutorial.
Switch the Steam Deck to Desktop Mode and open the web browser.
Go to the Final Fantasy XIV Loadstone download page on the official site. Select the Windows download.
In the Steam Deck desktop, navigate to your Downloads folder. Add the FFXIV installer EXE as a Non-Steam Game in your Steam library.
Right-click the game, and in Properties, set the Proton compatibility tool to Experimental.
Run the installer, selecting your SSD drive as the install location.
This should be your C Drive. For SD card installs, try your D drive.
Make note of the install location; you will need this later.
Once installed, remove the FFXIV installer from your Steam library.
Add ffixvboot.exe from the install location as a Non-Steam game. This is the actual game launcher.
You can find this by going into your root download folder (C drive for SSD), then open the run folder, then open the media folder, after opening the mmc folder, next you'll open the Final Fantasy folder, then you'll hit a Square Enix folder, open that up and find the FFXIV (or Final Fantasy XXIV) folder. Finally, you'll want to select the ffixvboot.exe
Simple version: C drive -> run -> media -> mmc -> Final Fantasy -> Square Enix -> FFXIV -> ffixvboot.exe
Right-click the game and set Properties to Proton Experimental again. You can also change the name on how it appears in your Library here.
Launch the game from your library and log in. Let it download updates.
Switch out of Desktop Mode to properly launch the game.
In controller settings, enable Expanded Hold Controls and auto hotbar switching.
While in controller settings, enable cross hotbar.
In display settings, disable hotbar 1 and 2
While in display settings, set graphics to High Laptop and turn off blur.
