Steam Deck Settings

Deck Settings
-GE Proton 6 or 7 (earlier the better)
-30fps cap (can push to 40fps in some areas)
-use “-force-gles20” launch option
-allowing tearing
-FSR Scaling filter (any sharpness is fine)
-manual GPU clock (keep at max)

In Game Settings
-AA off
-occlusion culling on
-tiled shadows on
-vertical sync on
-texture filtering on
-framerate cap 30

One drawback of using the older GE Proton is that the game won’t recognize the default gamepad scheme the game has. So you’ll need to use the “keyboard and mouse” layout. So if you launch the game and find controls aren’t working you need to make that adjustment.

I have a layout up in the community tab you can use as well. It’s named “Steam Deck Layout for Older GE Proton”.

Looking forward to the optimizations for Steam Deck! But these settings should get people playing comfortably on day one!

If you use Cryoutilities on Deck or want to install it, that is another way to get it stable on Deck!

Maxed out settings, newest proton (so you wont lose the controller support) 60fps stable.

Here is how:
1. Install Cryo Utilities (if you haven't already, it's great)
2. Configure to use recommended settings
3. Increase VRAM usage:
Go to the Steam Deck Boot/Setup Tool (power the SD down, reboot by pressing Volume Up and Power) go to Utility > Advanced > UMA Frame Buffer Size, change this to 4GB

Finally ensure that this launch option is added to run the game with Vulkan:
-force-vulkan

Please YouTube or Google Cryoutilities if you do not have it installed and need help.
