Grim Dawn on Steam Deck OLED | Best Settings for Stable 45FPS & 5 Hours Battery Life

Grim Dawn is one of my favorite ARPGs, and I’ve already played 100+ hours on the Steam Deck OLED. In this video, I share my custom graphics settings, which are optimized to lock the game at 45 FPS.

These settings give you a stable experience even in the most demanding scenes with tons of monsters and visual effects. Unlike max settings (where you’ll run into stutters and freezes), my setup provides a smooth console-like experience on handheld.

🔋 With these optimized settings, the Steam Deck OLED lasts up to 5 hours on a single charge – something no other handheld console can offer right now.

📌 Highlights:

At the start: showing maximum FPS values

5:48 – locked 45 FPS gameplay showcase on the final map with heavy combat
