Vulkan-to-DirectX 12 translation tool used in Valve's Proton now supports AMD's FSR4 and Anti-Lag, while Nvidia's DLSS4 remains unsupported — FSR4 now also works on older GPUs, VKD3D-Proton v3.0 brings other performance improvements

Valve's Proton now supports AMD's FSR4 and Anti-Lag, but Nvidia's DLSS4 remains unsupported. FSR4 now works on older GPUs, and VKD3D-Proton v3.0 brings performance improvements. The translation tool update includes FSR 4 support, Anti-lag support, and a DXBC shader backend rewrite. Linux gamers can expect enhanced compatibility and performance when running DirectX 12-based Windows games through Proton. Additionally, experimental support for Work Graphs has been added to potentially boost 3D rendering efficiency.
