NVIDIA DLSS for DX11 and DX12 games now available through Proton for Linux


As promised last month, after NVIDIA DLSS was first released on Linux via Valves Proton with compatibility for Vulkan games like DOOM Eternal, Wolfenstein Youngblood and No Man’s Sky, the new version of Proton (6.3.8) was released yesterday and has added NVIDIA DLSS support for DirectX 11 and DirectX 12 games.

Needless to say, this is by far the largest group of games compatible with NVIDIA’s deep learning super sampling technology, out of the 130+ games and apps that support it. For example from the latest DLSS additions Deathloop, Back 4 Blood, Battlefield 2042, Marvel’s Guardians of the Galaxy, Grand Theft Auto: The Trilogy – The Definitive Edition, Alan Wake Remastered, FIST: Forged In Shadow Torch, Bright Memory Infinite, Jurassic World Evolution 2, Chivalry II, The Elder Scrolls Online, Swords of Legends Online, Hot Wheels Unleashed, and Assetto Corsa Competizione are all DX11 and / or DX12 titles. Only Crysis Remastered Trilogy, Rise of the Tomb Raider, Shadow of the Tomb Raider and Baldur’s Gate III support Vulkan.

Hellblade: Senua’s Sacrifice PC update adds ray tracing reflections / shadows, DLSS and FSR

In addition to the NVIDIA DLSS expansion, the latest version of Proton also improved compatibility for a number of popular titles (see below) and added initial support for a few games that use BattlEye Anti-Cheat: Mount & Blade II: Bannerlord and ARK: Survival Evolved. This is important as part of Valve’s ongoing work to make more games with anti-cheat engines compatible with Steam Deck running on Proton.
