Pre-Installation Requirements

There are a few things that you’ll want to secure before jumping on this method, and they are as follows:

• Steam Deck (Any Size)
• SD Card, 128 GB or Larger Recommended
• Bluetooth Keyboard & Mouse (Not required, but recommended for ease)

Also, just to keep things from getting confusing, if you have tried to install the Final Fantasy XIV Steam Version, uninstall that before starting these steps to avoid confusion. It makes things a bit easier when trying to track down the FFXIV Launcher Client when the time comes.

Why Use the Proton Method Instead of XIVLauncher?

Editor’s Note: If you’ve done the research, you may have read that the XIVLauncher is a much faster method of installing Final Fantasy XIV on Steam Deck. While there is truth to this claim, most Steam Deck 64 GB owners are unable to perform the XIVLauncher method. Even when performing the steps correctly, you will likely encounter two issues:

• The Steam Deck Controls don’t work (No Device Located)
• Dalamud Error (When attempting to select a Data Server)

This issue appears to specifically affect Steam Deck 64 GB owners attempting to install Final Fantasy XIV on the SD Card. We’ve reached out to goatcorp in their Discord server and were unable to verify a solution.

While the Proton method may be a longer process, we can personally confirm that the installation works without issue, saving you a major headache in the long run. We hope this helps!

No matter if you’re playing with the Steam Deck Controls, or plan on docking and using a Keyboard and Mouse, the Steam Deck is the perfect way to play Final Fantasy XIV on the go. Now that you’re ready to jump into the game and its countless expansions, get ready for the ride of a lifetime.
