Valve confirms FSR 4 on Steam Machine, but not at launch
Valve says AMD's FSR 4 upscaler is coming to Steam Machine but won’t be ready at launch; FSR 4 should deliver notably better image quality and allow lower internal render resolutions, easing CPU bottlenecks on SteamOS. The exact release window isn’t fixed, but it’s expected to roll out with Proton updates and automatic upgrades via the AMD software, similar to Windows; on Linux, enabling FSR 4 currently requires manual steps.
