Today, The Khronos Group, an open consortium of industry-leading companies creating advanced interoperability standards, announces that LunarG has released the Vulkan Software Development Kit (SDK) version 1.2.162.0, with full support for the new Vulkan raytracing extensions, including Validation Layers and integration of upgraded GLSL, HLSL and SPIR-V shader tool chains. The Khronos open source Vulkan Samples and Vulkan Guide have been upgraded to illustrate raytracing techniques. Finally, with production drivers shipping from both AMD and NVIDIA, developers are now enabled to easily integrate Vulkan raytracing into their applications.
Khronos released final Vulkan raytracing extensions in November 2020 to seamlessly integrate raytracing functionality alongside Vulkan's rasterization framework, making Vulkan the industry's first open, cross-vendor, cross-platform standard for raytracing acceleration. Vulkan raytracing can be deployed using existing GPU compute or dedicated raytracing cores. The Vulkan SDK now integrates all the components necessary for developers to easily use the new raytracing extensions, such as new shader tool chains, without needing them to be built from multiple repositories, and supports raytracing validation within the SDK validation layers.
"Shipping API specifications was just the first step in building the developer ecosystem for Vulkan raytracing, we now have tools and samples to truly enable developers to tap into the power of cross-platform raytracing acceleration," said Daniel Koch, senior graphics system software engineer at NVIDIA and Vulkan raytracing TSG chair at Khronos. "One of the key requests from the developer community was the ability to easily bring DirectX 12 raytracing (DXR) code to Vulkan. We have achieved that through delivering a carefully designed superset of DXR, and integrating Vulkan raytracing support in the DXC open source HLSL compiler."
As outlined earlier this year, production-ready use of HLSL in Vulkan has been achieved through integrating a SPIR-V backend into DXC, Microsoft's open source HLSL compiler. Support for Vulkan raytracing has now been integrated into DXC, enabling developers to use HLSL shaders in Vulkan raytracing applications, including porting raytracing applications to Vulkan from DXR. Vulkan is also used as a backend for layered implementations of APIs such as DirectX 12. Through the design of Vulkan raytracing, projects such as vkd3d-Proton will be able to efficiently support layered DXR over Vulkan.
Production Vulkan drivers that include the Vulkan raytracing extensions are now shipping for both AMD and NVIDIA GPUs, starting with the AMD Radeon Adrenalin 20.11.3 and NVIDIA R460 drivers for both GeForce and Quadro on Windows and Linux. The Vulkan raytracing extensions will also be supported by Intel Xe-HPG GPUs, available in 2021, with driver support provided via regular driver updates.
The Khronos Group is actively monitoring developer feedback on the Vulkan raytracing extension and ecosystem artifacts through the Vulkan issues tracker on GitHub.
Industry Support for Vulkan raytracing
"4A Games was one of the earliest adopters of hardware level raytracing by developing the first Real-Time Raytraced Global Illumination system in a video game as released in Metro Exodus, and we are excited at the addition of a vendor agnostic Vulkan implementation in the industry. We look forward to seeing how this technology progresses,"
— Oleksandr "Oles" Shyshkovtsov, CTO, 4A Games.
"Standardizing raytracing in Vulkan is an important step towards making raytracing available across a wide range of devices, as well as enabling developers to use this technology to its full advantage. AMD supports all of the major features in this extension, including ray shading and ray queries in our AMD Radeon Software Adrenalin Edition driver. We are also working with developers to ensure great performance from our Vulkan raytracing implementation thanks to hardware raytracing support on AMD RDNA 2 architecture-based graphics cards; these efforts will help us to provide end-users with even more visually stunning graphics on AMD Radeon graphics cards,"
— Andrej Zdravkovic, senior vice president, software development, AMD.
"During the development of Rage 2 and other games, Vulkan gave us great flexibility when looking at deployment on multiple platforms. As the Apex Engine looks to adopt and avail of the latest hardware developments, it is great to see Vulkan keeping pace and investing in support for cutting edge features like hardware accelerated raytracing,"
— John Fuller, managing director, Avalanche Studios Group.
"Being one of the first adopters of Vulkan in our Rocksolid Engine already in 2015, we're thrilled to now add support for Vulkan raytracing.

We're also working to introduce raytracing for automotive instrument clusters and other in-car screens and Vulkan raytracing extensions are important enablers for this,"
— Tero Sarkkinen, Founder and Chairman of the Board of Basemark.
"Blender's mission is to get the best of the world's CG technology in the hands of artists as free/open source software. Industry-wide accepted open standards are essential for our goal. For that reason I'm proud to see the industry having agreed on the Vulkan raytracing API. This is going to be huge! For us, the upcoming raytracing functionality was a big motivation for why we are working on Vulkan real-time rendering already since 2019,"
— Ton Roosendaal, chairman Blender Foundation.
"In the past 20 years, rasterization techniques were at the core of innovation in real-time rendering. At Crytek, the Vulkan API is playing a major part in driving advancements in this area, helping us to deliver a high-performance game-engine with outstanding visuals across different platforms and operating systems. We are pleased that Khronos is releasing vendor-independent Vulkan raytracing extensions that define essential functionality for bringing real-time raytracing to Vulkan supported applications. Similar to the rasterization domain, this extension plays a major part in our plans for offering cutting edge raytracing functionality in CRYENGINE, while benefiting greatly from hardware-specific implementations of each vendor,"
— Theodor Mader, technical director, CRYENGINE/Crytek.
