Valve has officially added support for both the standard and experimental Proton compatibility layers which will allow Windows games to run on Linux. The experimental version will be compatible with Nvidia Deep Learning Super Sampling (DLSS) in DirectX 12 games, while the regular version broadens support to more titles.
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, since it requires proprietary Nvidia machine learning silicon, but it was recently revealed that the Steam Deck will support AMD’s (arguably much less capable) FSR.
Valve says 6.3-8’s release includes “support for an initial set of BattlEye games,” referring to the BattlEye anti-cheat software that may or may not be holding back some of the most popular Steam games from having proper working multiplayer modes on the Steam Deck and Linux.
All of this work hints at better Proton compatibility and a smooth user experience when Valve starts shipping its Steam Deck gaming console to the masses in December. Updated Proton software will allow both the Steam Deck and Steam on Linux to support many more games.
