Ephinea Steam Deck Setup

[T_T1K]

Ephinea Phantasy Star Online: Blue Burst runs on Steam Deck, but some additional configuration is needed compared with Windows. This step-by-step guide shows you how to run Ephinea on a Steam Deck, enabling all action shortcuts and improving camera control: https://ragol.co.uk/guides/ephinea-steam-deck-setup/

Some additional settings I’m using to maximise battery life:

1. Ephinea Launcher → Options → Set Resolution to 1280 x 800 (all other settings set to default)
   
2. Steam → QAM → Enable Use per-game profile
   
3. Set Frame Limit to 30 FPS
   
4. Enable TDP Limit and set it to 7 Watts 5 Watts
   
5. Enable Manual GPU Clock and set it to 700 MHz 200 MHz
   

Since Sega locked PSO to 30 FPS and it’s not a demanding game, you could probably push these even lower. Even with these settings, I’m getting 4+ hours of battery life

Edit: Pushed the settings lower.
