Years after its failed Steam Machines, Valve is slowly but surely improving the state of Linux gaming. From a report: The company’s upcoming Steam Deck handheld runs atop Linux, and its Proton compatibility layer lets it — and other computers — play Windows games as well. Now, Valve has officially added support for Nvidia’s DLSS machine learning temporal upscaling technique to Proton, potentially bringing big FPS boosts and less flicker in games that support the technology.
Proton 6.3-8 is the first stable release to include support for DLSS, after the feature previously hit experimental builds in October, though it appears you’ll still need to set PROTON_ENABLE_NVAPI=1 and dxgi.nvapiHack = False to turn it on. DLSS won’t come to the AMD-powered Steam Deck, of course, since it requires proprietary Nvidia machine learning silicon, but we recently learned the Steam Deck will support AMDâ(TM)s arguably much less capable FSR.
