The 2018 X.Org Developer's Conference (XDC2018) videos have now been posted online. XCD 2018 saw many Khronos members sponsor this conference, including Igalia, AMD, Arm, COLLABORA, Google, NVIDIA, Intel and Valve. The talks covered Vulkan, OpenGL, OpenGL ES, OpenCL, SPIR-V, GLSL and OpenXR. We've compiled a list of all the videos discussing these Khronos standards here, or you can watch all the videos from the conference on the X.Org Foundation YouTube channel.

A libre-licensed software implementation of Vulkan has started up again. Originally started in c++ in 2017, for a reimplementation Rust has been chosen for its concurrency and memory-safety features, and Rust's LLVM support makes it highly portable. With OpenGL having both llvmpipe and MesaGL for fallback and testing purposes, it seems strange that there does not exist a corresponding Reference Implementation for Vulkan: the only implementations available are in hardware, making it extremely challenging for anyone considering entering the market. Kazan helps fill that gap. Sponsorship of this entirely libre-licensed project welcomed.

VRWorks 3.0 Graphics SDK has OpenGL Examples for TuringNVIDIA has released the new VRWorks Graphics SDK V3.0 for application and headset developers along with the NVIDIA display driver 411.63, both updated for NVIDIA's new Turing GPU generation. The drivers are available for download and the SDK has been posted. The SDK includes an OpenGL sample to demonstrate Turing's “Variable Rate Shading” (VRS) feature showing how to vary fragment load across the screen, e.g. for foveated rendering. Another sample demonstrates Turing's “Multi-View Rendering” (MVR) feature by showing how to render the same scene from different viewpoints. There are Vulkan versions of the samples too.

Qualcomm released a new version of Snapdragon Profiler this week. The system profiler for mobile-based hardware using Qualcomm's Snapdragon chips now includes support for Vulkan frame captures. Labelling the new Vulkan capability as a beta feature, the 2018.2 release of Snapdragon Profiler includes additional fixes for OpenGL ES frame captures, saving and loading Profiler sessions, and more.

Intel’s driver team has published a new graphics driver for all recent GPUs (Intel 6th, 7th and 8th Gen processors) on Windows 10. This new driver (version 25.20.100.6323) brings support for Windows 10 October 2018 Update (version 1809 with WDDM 2.5) and HDR for embedded laptop panels. Hardware support now included up to Vulkan 1.1.83, OpenCL 2.1 and OpenGL 4.5. Complete details are in the Intel Release Notes PDF.

The first GPUs from the Turing architecture have arrived with lots of new features. Extensions have been added to both Vulkan and OpenGL to give developers access to these new features. The various Khronos Registries and Repositories have been updated to include the specifications and tools for the new extensions. The Vulkan and OpenGL extensions are enumerated on the NVIDIA website to provide developers access to these new features.

Forsaken Remastered was just updated with Vulkan support! If you're on Linux, you're probably hitting 60fps with the existing OpenGL renderer, but it's good to be future proof. If you're on a Mac, though, you definitely want to switch. On my MacBook, the framerate goes from around 15 to a solid 60! On macOS, Vulkan support is supplied by MoltenVK, which we now ship with the game. It should work on any Mac that supports Apple's Metal API, which MoltenVK uses to make Vulkan work. You can change from OpenGL to Vulkan in-game in the "Video" options menu.

Khronos at SIGGRAPH 2018–Next week!SIGGRAPH is next week! The conference is August 12–16 in Vancouver Canada. For those going, Khronos will be hosting several Birds of a Feather sessions. For all those folks that will not be present, we will be offering live streaming of all our sessions (glTF, WebGL, OpenXR, Vulkan and OpenGL) on the Khronos Group YouTube Channel, and will follow up with recorded video the following week. For complete details on all the sessions, please ask your friends and co-workers to take a look at our SIGGRAPH event page! A special thanks to our Diamond sponsor NVIDIA, Gold Sponsor LunarG, and Silver sponsors Cesium and AMD, for making possible the Khronos Networking Reception at the end of the day.

The glTF session at SIGGRAPH may only be 50 minutes long, but it will be action packed. Don't miss this years fast moving glTF session with these speakers:

  • Ecosystem update: Patrick Cozzi, Cesium
  • glTF for artists: Patrick Ryan, Microsoft
  • TurboSquid - Beau Perschall

Apple has published an official list of all of their devices that use OpenGL and OpenCL, including which version is supported. The earliest machines date back to 2007. The most recent machines to support both OpenCL and OpenGL are the 2018 MacBook Pro 13 and 15 inch. Both machines support OpenGL 4.1 and OpenCL 1.2.

Magic Leap released a handful of tutorials and assets files that will help developers get a head-start in creating mixed reality content on Magic Leap One. Magic Leap said that Unity and Unreal already offer optimizations for Magic Leap hardware. The headset has full support for OpenGL 4.5 and OpenGL ES 3.1, but Magic Leap recommends building applications with the Vulkan API for the best performance.
