AMD released a new version of their graphics driver v19.6.2 on Monday June 17th. With with release they have added support for 5 new Vulkan extensions: VK_EXT_full_screen_exclusive, VK_EXT_host_query_reset, VK_EXT_separate_stencil_usage, VK_KHR_uniform_buffer_standard_layout and VK_AMD_display_native_hdr. Learn more with a brief description of what each extension does and how to use them on the GPUOpen blog.

In 2016, the Uber Visualization team released an open source version of and, two Khronos Group WebGL™-powered frameworks for visualizing and exploring huge geospatial data sets on maps. Since then, the technology has flourished into a full-fledged suite of over a dozen open source WebGL and GPGPU data visualization libraries and tools, known collectively as, the newest addition to the family, adds support for loading and rendering glTF™ assets across the tech stack. Read the blog for complete details.

With the growth and adoption in mobile, web, and immersive platforms, 3D is poised to grow as a new shopping medium. Product manufacturers, retailers, marketing, and advertising platforms can use 3D to show virtual products to end-users to help them better understand a product online prior to purchasing and to help build brand loyalty after purchase. The Khronos has a track record of openness and responsiveness, with a well-proven IP Framework and multi-company governance model. The Khronos 3D Commerce Exploratory Working Group could directly leverage the work of several existing Khronos Working Groups, including: glTF, WebGL, Vulkan, and OpenXR. With enough industry support, this Exploratory Group will evolve into a Working Group to work on the development of such standards.

Q2VKPT – short for “Quake II Vulkan Path Tracing” – was a research project led by Christoph Schied, an engineer eager to bend the possibility space of computer graphics. Using id’s 22-year-old game as a foundation, Christoph was able to make real-time path tracing a reality on consumer hardware. His project caught the attention of Quake fans, tech journalists, and NVIDIA. Learn more about Q2VKPT in this twenty minute video from GDC.

Tips and Tricks: Vulkan Dos and Don’tsThe increased performance potential of modern graphics APIs is coupled with a dramatically increased level of developer responsibility. Optimal use of Vulkan is not a trivial concept, especially in the context of a large engine, and information about how to maximize performance is still somewhat sparse. The following document is a compilation of wisdom from some of the Vulkan experts at NVIDIA. It is not exhaustive, and is expected to be augmented over time, but should be a useful stepping stone for developers looking to utilize Vulkan to its full potential.

C++ Lambdas, first introduced in C++11, are an important part of the way that the SYCL standard is defined and implemented. SYCL is required to handle different types and pass around functions so lambdas are a good fit allowing anonymous function objects to be passed to SYCL kernels. We talk about how we use lambdas in our guides and documentation, but never about how lambdas work or even how to use them in SYCL, so in this blog post we will examine how they can be used in SYCL.

Version 1.93 of the Vulkan Hardware Capability Viewer is now available for all platforms (Windows, Linux, Android) at

This version fully supports Vulkan 1.1 and adds support for reading additional features and properties for the following extensions:

- VK_EXT_fragment_shader_interlock
- VK_NV_shader_sm_builtins
- VK_KHR_depth_stencil_resolve properties
- VK_EXT_buffer_device_address features
- VK_EXT_pci_bus_info features

Additional changes for this version:

- Updated to Vulkan headers 1.1.110
- Reworked Android UI/UX

This version has also been published to Google Play and can be installed directly from there, old version will be automatically upgraded.

Bringing Open Standards for Safety Critical to the Automotive IndustryOpen standards are opening up supply options for OEMs and Tier 1s in the automotive industry while also satisfying safety concerns. lya Rudkin, chair of the Khronos Safety Critical Advisory Forum discusses why open standards are increasingly important in safety critical applications in the automotive market. Comprising hardware SoC designers, software developers with safety critical experience, cybersecurity experts, and safety functional managers in various safety critical domains, the forum has combined a wealth of graphic and data compute expertise with functional safety experts. For experienced practitioners in the field of safety critical system design who would like to participate in the advent of industry safety standards for next-generation automotive, Khronos invites them to learn more about the Khronos Safety Critical Advisory Forum here.

AWE Nite SF is a place for developers, creators, investors, founders, corporate decision makers and curious folk to come together to celebrate the activity and devote conviction around building an Augmented Reality hub in Silicon Valley.
