On June 21, Arntzen Software developer Hans-Kristian Arntzen released Version 2.13 of VKD3D Proton, which implements Shader Model 6.8, improves OpenVR and OpenXR support, "reduces memory bloat on AMD cards," updates Nvidia Reflex support, and even fixes some title-specific graphical issues, among other additions. VKD3D Proton is a branch of VKD3D focused on improving DirectX12 feature support within games running under Valve Proton in Linux, and its improvements are eventually rolled into mainline Proton (shipped by default with Steam Deck) as well.
While some may associate news relating to Valve Proton with being primarily Steam Deck-oriented, Proton is meant for all Linux gamers to enjoy, and the dev-focused VKD3D Proton branch is actually much more focused on high-end hardware.
