Valor Mortis - Steam Deck First Look - Surprising results!

In this Steam Deck technical first look, we test the Valor Mortis pre-alpha demo (October 2025 build) - a gritty Soulslike set in the French Revolution, blending Bloodborne and BioShock elements with Unreal Engine visuals. We’re checking how it performs on the Steam Deck OLED - testing TSR, FSR, XeSS, and even lossless scaling to see which upscaler works best. FPS, stability, battery life, and controls - all covered. 💬 Let me know if you tried the playtest and how it runs for you. This is an early build, but the results are surprisingly solid for Unreal Engine.
