Valve and AMD to bring FSR 4.1 to SteamOS and Steam Machine

Valve is working with AMD to integrate the company's latest FidelityFX Super Resolution (FSR) 4.1 upscaling technology into its SteamOS platform and upcoming Steam Machine hardware, according to recent statements and technical developments. The collaboration aims to bring improved image quality and performance to AMD-powered gaming systems running Valve's Linux-based operating system.

A Valve developer confirmed the company is working with AMD to bring FSR 4 to the Steam Machine, stating the feature is "coming soon" but without providing a specific release date. The developer hinted the SteamOS rollout could align with the Windows release schedule for the technology. This integration is seen as crucial for the Steam Machine, a forthcoming gaming PC from Valve that is expected to rely on AMD hardware and SteamOS. The machine's semi-custom GPU is based on AMD's RDNA 3 architecture.

Supporting evidence for this integration effort emerged on June 22, when files related to FSR 4.1 were discovered in the Proton Experimental branch, Valve's compatibility layer for running Windows games on Linux and SteamOS. These files were subsequently removed, suggesting a testing build was released...
