Quick answer: Avalanche's November 5, 2026 Hogwarts Legacy PC patch (build 2153883) adds Steam Deck OLED and Steam Machine support with optimized graphical settings and a virtual keyboard, plus DLSS 5, XeSS updates, and XeSS Multi-Frame Generation.
Avalanche Software's November 5, 2026 Hogwarts Legacy PC patch is live as build 2153883 on Steam, the Epic Games Store, and Windows PC. Portkey Games Support notes say it adds support for Steam Deck OLED and Steam Machine, including optimized graphical settings and a virtual keyboard.
The same patch updates NVIDIA upsampling to DLSS 5 and adds a DLSS 5 Neural Rendering option. Neural Rendering is off by default and currently requires an RTX 50 Series GPU with GeForce Game Ready Driver 616.64 or newer. Intel XeSS is updated as well, with XeSS Multi-Frame Generation added. The notes also fix some graphics options that could save incorrectly, update minimum GPU driver notifications, reduce restarts after certain frame-gen changes, and add support for NVIDIA RTX Spark Laptop.
The device wording names Steam Deck OLED specifically, not every Deck variant, and does not promise a frame-rate target. Players still need to check the in-game options after installing. Mixed News reports the same patch summary from Avalanche's notes.
