These are the best settings for Diablo IV on Steam Deck and SteamOS.
Diablo IV is right around the corner with an early access launch on June 2nd, so naturally we were wondering how the new Diablo game runs on Steam Deck. Thankfully, we know the answer thanks to the betas that ran in March.
If you followed our Diablo IV Steam Deck installation guide, you'll know Diablo IV runs on Steam Deck.
But when you get into the game here are a few steps to make Diablo IV run better on Valve's Steam Deck:
Best Settings for Diablo IV on Steam Deck
First of all, you need to choose the correct Proton version.
We had the most luck so far with Proton 6.3 and GE-Proton 7-51 (this is a built especially meant for the Diablo IV beta). Follow our guide on how to install GE-Proton.
Next, following our graphic settings guide, cap your refresh rate and framerate limit to 40. While we can play the game on low at 60fps, we personally had too many drops that made for an unstable game, so dropping it to 40 makes for a better experience.
The next big change you want to make is to set FSR 2.0 (that‘s the one in the graphic settings of the game, NOT the Steam Deck‘s built-in one) to `Quality`. In-game it is called FidelityFX Super Resolution.
With these settings, we were able to select the in-game preset for Medium settings with a more or less stable framerate.
