Altheia: The Wrath of Aferi is a stunning action RPG with puzzle-solving elements, and it feels like a game that was made for handheld play on the Steam Deck. At the moment, it carries an Unknown Steam Deck rating, which simply means Valve hasn’t officially tested it yet. But don’t let that label fool you because Altheia runs great on the Deck. Here’s what you need to know about performance, controls, and overall playability.
Best Graphics Settings for Altheia: The Wrath of Aferi on Steam Deck
Yes, you can play Altheia: The Wrath of Aferi on Steam Deck. During my testing, I didn’t encounter any performance issues like crashing, stuttering, or freezes—everything ran smoothly. The developer also recommends using a controller, and the default Steam Deck layout works perfectly. All in-game button prompts display correctly, making it a natural fit for handheld play.
For the best experience, I recommend disabling Steam Deck’s overlay settings and letting the in-game settings take full control. This helps reduce latency. To do this, press the button with three dots, head into the Performance section, and toggle Disable Frame Limit and Allow Tearing. After that, go into the in-game graphics menu and set V-Sync to Full.
Here are the best Graphics settings for Altheia: The Wrath of Aferi:
- Resolution: 1280 x 720 (closest to the Deck’s native resolution)

- Anisotropic Filtering: On
- Shadows Quality: Ultra
