NVK Open-Source Vulkan Driver Adds Experimental DLSS Support
confidence 95%The open-source NVK Vulkan driver for Linux has integrated experimental support for NVIDIA DLSS in Mesa 26.2-devel. This update utilizes the VK_NVX_binary_import extension to load precompiled CUDA binaries. A stable release of Mesa 26.2 is expected in August 2026.
What's confirmed:
- Experimental DLSS support for the NVK Vulkan driver is merged into Mesa 26.2-devel.
- The feature implements the Vulkan extension VK_NVX_binary_import to load precompiled NVIDIA CuBIN CUDA binaries.
- The DLSS feature is gated behind the NVK_EXPERIMENTAL=dlss environment variable.
- Mesa 26.2 stable is targeted for August 2026.
- The development involved Valve developer Autumn Ashton and Thomas Andersen.
Still unconfirmed:
- DLSS binary compatibility depends on available GPU-specific bytecode.
