Fall Guys Steam Deck configuration guide [FULLSCREEN FIX]

Includes EasyAntiCheat setup and a fix that forces the game to run at native 16:10 aspect ratio.

Running the Game

---

Prerequisites

First, install the game as you normally would with any steam game.
*Additionally, you need to search for and install "Proton EasyAntiCheat Runtime" on Steam.

Proton-GE

With the default proton installation on SteamOS, Fall Guys fails to launch. A fix for this is to install the community built "Proton-GE".

• Switch to desktop mode (hold power button and press Switch to Desktop
  
• Open "Discover" from the start menu
  
• Search for and install ProtonUp-Qt
  
• Launch ProtonUp-Qt from the start menu
  
• Click "Add version" and install GE-Proton7-[Whatever the latest version is] (you might have to try other versions if you have issues)
  
• Once it's done installing, return to Gaming Mode and go to the Fall Guys page in your library
  
• Click settings and go to Properties... > Compatibility
  
• Select "Force the use of a specific Steam Play compatibility tool
  
• Choose GE-Proton7-[Version you downloaded]

And now you can play Fall Guys as you normally would! Go to the troubleshooting section if you're still having issues. I'd also recommend setting the Select button to [Shift+F3] to open the Epic Games overlay.

Fullscreen Fix

The game has some trouble detecting the 16:10 aspect ratio display on the Steam Deck, so you can edit some text files to force the game to run at 1280x800p

• Launch desktop mode & download GHex from the Discovery store
  
• In desktop mode - open steam & go to Fall Guys
  
• Click the settings icon & go to Manage > Browse local files
  
• Look for "unityplayer.dll" & hover over it, then click the left trackpad & click "open with" & search for GHex [it's under the development tab]
  
• Click the search icon on the top right & search for "39 8E E3 3F" & replace it with "CD CC CC 3F" for BOTH INSTANCES [click "find next" after replacing the first one & also replace the second]
  
• Click the save icon on the top right and close
  
• Switch back to gaming mode & launch the game, it should be fixed

IF IT IS STILL NOT FIXED: open Fall Guys & go to the in-game video settings and change the resolution to 1280x800, apply that & you're done.

Troubleshooting

---

EasyAntiCheat error in the main menu of Fall Guys

• Make sure you installed "Proton EasyAntiCheat Runtime on Steam.

Stuck on EasyAntiCheat loading screen when first launching Fall Guys

• Try using GE-Proton7-15 when first setting up the game, then switch to a newer version. Newer versions have some important stability fixes.
