Here's how to run Diablo 4 on Steam Deck

By - | Views: 78,602

Diablo 4 is currently in Beta and due to launch soon, so here's how to get it working on Steam Deck. The same steps can be used to get it working on Linux desktop too. Update: You can also use the NonSteamLaunchers script I covered here that does a lot of the work for you.

You can see the video here, with the text guide below it:

Text Guide

  • Go into Desktop Mode (Steam button - Power - Switch to Desktop).
  • Download the launcher in your web browser (Chrome / Firefox etc).
  • Download ProtonUp-Qt from the Discover app.
  • Inside ProtonUp-Qt, download the new "GE-Proton7-51-diablo_4_beta". Once done, close ProtonUp-Qt.
  • Inside Steam: hit Add A Game in the bottom left, select Add a non-Steam Game and hit Browse.
  • Go into your Downloads folder in the file browser, select All Files from the bottom and then select the "" file.
  • Once added, search for the Battle.Net installer shortcut in Steam. Right click -> Properties -> Compatibility -> Tick the box and select GE-Proton7-51-diablo_4_beta.
  • Now run it and install it. Once installed, close it, do not login.
  • Right click on the shortcut again, go to Properties, hit Browse and update the shortcut to point to the " Launcher.exe". It's location will depend on where you installed it.
    • SD Card: /run/media/mmcblk0p1/
    • SSD: /home/deck/.steam/root/steamapps/compatdata/ (then find the most recently created id) /pfx/drive_c/Program Files (x86)/

Now you will have Battle.Net set up and you can launch it in Gaming Mode, in the Non-Steam section of your Steam Library. You may need to manually bring up the on-screen keyboard with STEAM + X, and you can use a mouse cursor by holding the STEAM button and using the Right Trackpad with Right Trigger as a mouse button.

The Battle.Net UI is cut off, but if you click about along the top of it, the app will flicker into focus giving you the install buttons at the bottom.

After that, you're free to install and run Diablo 4. If you get a GPU error message, just hit OK and it will run.

This is just one possible way to do it. You could also use Lutris to install Battle.Net but I personally prefer on Steam Deck specifically to keep everything inside Steam if I can.

i was able to install by adding its installer via the "add non steam game" method. but after exiting out of the login in window, as stated, and going back to to change its target to the launcher, it wouldn't launch for the life of me. the way i finally got it to work was by removing the prefix completely, reinstalling it, but this time installing it to a different steam library on one of my many nvme's on my system instead of the default .steam in my home directory so its installed in the commom folder, instead of the compdata folder, then exiting from the login window, going back into steam, removing the installer prefix instead of changing its target so it deletes the compdata folder, going back to "add non steam game" and selecting the - launcher.exe that way. it recreate a brand new prefix linked to the actual install folder and it launches!
i saw other people complaining about it not launching too if you just try to change the target location.

Just a note for my fellow players: I had some troubles with a super laggy battle net launcher. Sometimes it would just take FOREVER to launch and become unresponsive. I did some research, and changed my dns from isp default to cloud flares and it fixed it immediately. Apparently battle net is finicky with dns.
