Valve improves Proton Experimental: NVIDIA DLSS 3 support and numerous changes for Linux gaming

Valve is improving its tool for running Windows games on Linux systems. The latest Proton Experimental update introduces support for NVIDIA DLSS 3, fixes numerous in-game bugs, and enhances overall performance on Linux-based platforms.

One of the most significant new features introduced in the latest version of Proton Experimental is integration with NVIDIA DLSS 3. This will allow gamers using NVIDIA RTX graphics cards to fully utilize the potential of DLSS 3, achieving higher gaming performance without a noticeable loss in image quality. The update also supports NVIDIA Optical Flow technology, which uses AI to provide smoother gameplay (frame generator). This is a huge step forward for the Linux gaming community.

Proton Experimental also includes fixes for popular games. Valve fixed bugs related to performance, stability, and controller support in Final Fantasy XVI, Yakuza 6, Hunt: Showdown, and Greedfall. One of the most significant changes is mod support in Doom Eternal.

The update brings improvements to DXVK and VKD3D-Proton, which play a key role in running Windows games on Linux. DXVK, a Vulkan-based layer, translates DirectX 9, 10, and 11 calls, allowing older games to run better. This resolves issues with cursor behavior, game engines, and compatibility.

VKD3D-Proton focuses on DirectX 12, making it ideal for high-performance systems. The update adds support for NVIDIA Reflex, reducing input latency, and OpenVR, improving VR game support. These integrations make gaming on Linux systems more competitive.

Steam Deck users, whose devices are powered by the Linux-based SteamOS, benefit in particular. Thanks to these changes, gaming on Linux is gradually becoming a viable alternative to Windows, offering an identical experience in many scenarios.
