Beaverton, OR – December 15, 2020 – 6:00 AM PT – 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 Ray Tracing 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 ray tracing techniques. Finally, with production drivers shipping from both AMD and NVIDIA, developers are now enabled to easily integrate Vulkan Ray Tracing into their applications.

Khronos released final Vulkan Ray Tracing extensions in November 2020 to seamlessly integrate ray tracing functionality alongside Vulkan’s rasterization framework, making Vulkan the industry’s first open, cross-vendor, cross-platform standard for ray tracing acceleration. Vulkan Ray Tracing can be deployed using existing GPU compute or dedicated Ray Tracing cores. The Vulkan SDK now integrates all the components necessary for developers to easily use the new ray tracing extensions, such as new shader tool chains, without needing them to be built from multiple repositories, and supports ray tracing validation within the SDK validation layers.

“Shipping API specifications was just the first step in building the developer ecosystem for Vulkan Ray Tracing, we now have tools and samples to truly enable developers to tap into the power of cross-platform ray tracing acceleration,” said Daniel Koch, senior graphics system software engineer at NVIDIA and Vulkan Ray Tracing TSG chair at Khronos. “One of the key requests from the developer community was the ability to easily bring DirectX 12 ray tracing (DXR) code to Vulkan. We have achieved that through delivering a carefully designed superset of DXR, and integrating Vulkan Ray Tracing 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 Ray Tracing has now been integrated into DXC, enabling developers to use HLSL shaders in Vulkan ray tracing applications, including porting ray tracing 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 Ray Tracing, projects such as vkd3d-Proton will be able to efficiently support layered DXR over Vulkan.

Production Vulkan drivers that include the Vulkan Ray Tracing 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 Ray Tracing extensions will also be supported by Intel Xe-HPG GPUs, available in 2021, with driver support provided via regular driver updates.

Industry Support for Vulkan Ray Tracing

“4A Games was one of the earliest adopters of hardware level ray tracing 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,” said Oleksandr “Oles” Shyshkovtsov, CTO, 4A Games.

“Standardizing ray tracing in Vulkan is an important step towards making ray tracing 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 Ray Tracing implementation thanks to hardware ray tracing 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,” said 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 ray tracing,” said 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 Ray Tracing. The first product to feature raytraced effects like reflections and global illumination will be the forthcoming GPUScore benchmark. We’re also working to introduce ray tracing for automotive instrument clusters and other in-car screens and Vulkan Ray Tracing extensions are important enablers for this,” said 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 ray tracing API. This is going to be huge! For us, the upcoming ray tracing functionality was a big motivation for why we are working on Vulkan real-time rendering already since 2019,” said 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 Ray Tracing extensions that define essential functionality for bringing real-time ray tracing to Vulkan supported applications. Similar to the rasterization domain, this extension plays a major part in our plans for offering cutting edge ray-tracing functionality in CRYENGINE, while benefiting greatly from hardware-specific implementations of each vendor,” said Theodor Mader, technical director, CRYENGINE/Crytek.
