Resident Evil Requiem runs way better on Steam Deck than I originally expected, and that’s the whole point of this video: I tested the opening sections, indoor scenes, outdoor segments, and the heavier Leon combat areas to find a balanced setup that targets a stable 40 FPS without making the game look like a blurry mess. Indoors the game behaves really well (mid-40s and sometimes higher), and the real pressure shows up outdoors and during multi-enemy combat—but it doesn’t collapse, it just needs to be tuned properly. I walk you through the exact in-game settings I’m using, focusing on the changes that actually matter on Deck. I turn off motion blur and hair strands (cool feature, but too heavy), keep textures on Low to avoid VRAM saturation and traversal stutters, and then claw back image quality with things like high anisotropic filtering and enabling screen space reflections. I also cover the FSR situation: you’re stuck with FSR here, and you will see shimmer in fine details, but on the small Deck screen it’s manageable. Finally, I explain the Proton fix for enabling FSR 3.1.5 without crashes (Proton GE 10-15 or Proton 10.0-4), give real battery expectations (around 2.5 hours OLED uncapped, closer to ~3 hours capped at 40), and I test Lossless Scaling as an optional path to a good-feeling 60 FPS experience—just don’t try Decky + Lossless Scaling tweaks that crash the game right now.
