NVIDIA Vulkan Ray Tracing Tutorial

The focus of this NVIDIA tutorial and the provided code is to showcase a basic integration of ray tracing within an existing Vulkan sample, using the VK_NV_ray_tracing extension. Note that for educational purposes all the code is contained in a very small set of files. A real integration would require additional levels of abstraction.

AMD: GDC 2019 presentations now online

If you weren’t able to attend GDC this year to catch the AMD Advanced Graphics Techniques Tutorial Day and the AMD Sponsored Sessions in person, or you did but still wanted to grab the presentation content for your archives, AMD thought it’d be a good idea to put together a list for both, like they did last year. Check out the lists for session and speaker names, and direct download links with file types and sizes.

As part of our optimisation work, we have added Vulkan support to the game. We have been able to do this not only for Beyond, but for the current live version of the game. OpenGL has been replaced by Vulkan. Many players, particularly players with AMD graphics cards, should see a performance improvement. Read on to learn more about Vulkan and VR announcements.

Flax Engine moves towards cross-platform gaming. Adding Vulkan rendering backend implementation into the engine resulting in greater efficiency, performance, and stability. We see a huge potential of Vulkan API as it opens ways to new areas for Flax to expand including Linux and Android support.

Arm Mobile Studio is a suite of free-to-use tools which help game and app developers to reach more of the mobile market by efficiently optimizing and debugging high-end content for all Android devices. It includes the Arm Graphics Analyzer to trace graphics performance issues easily, and Arm Streamline performance analyzer, for a whole-system view of performance to determine bottlenecks quickly across both the CPU and GPU. Arm Mobile Studio supports frame-by-frame analysis of OpenGL ES and Vulkan content and lets you trace Vulkan, OpenGL ES, EGL and OpenCL API calls easily in your game from within the Unreal game engine.

There are several great Khronos related meetings for April 2019: “OpenXR 0.90 Provisional Specification Review” on April 10th in Cambridge MA USA, “Munich Meetup April 2019” on April 12th in Munich Germany with Dr Chajdas and friends covering Vulkan, SPIR-V and GLSL, and starting on April 16th is a three part meet up on “A Gentle Introduction to Shaders 1” in London UK. Learn more about these meet ups and how Khronos can help support your Khronos related meet up.

Radeon GPU Analyzer (RGA) is thte AMD offline compiler and integrated code analysis tool, supporting the high-level shading and kernel languages that are consumed by DirectX 11, Vulkan, OpenGL and OpenCL, including HLSL, GLSL, the OpenCL kernel language, and SPIR-V. Along with support for Vulkan in the RGA GUI, the biggest new feature in RGA 2.1 is a new analysis system that lets you obtain the GCN machine ISA and hardware resource information, using the compiler in the running driver that you have in your system. Learn more on the Radeon GPU Blog from AMD.

NVIDIA VKRay is a set of three extensions that bring ray tracing functionality to the Vulkan. VK_NV_ray_tracing is the stable registered extension for adding ray tracing effects to Vulkan raster applications. Callable shaders provide applications with the means to reuse shading code across many different objects. The new stable extension includes API updates for cleaner code and flexible memory management. Learn more in the NVIDIA Developers News center.

Google announces Stadia, a game streaming service using Vulkan

At its GDC 2019 keynote, Google announced Stadia, a cloud streaming service allowing graphically-intensive games to be available to anyone who can run Chrome. Doom Eternal will be one of the first games on the platform, streaming at 4K resolution, 60 fps. Google has partnered with AMD to design a custom GPU with “more than ten teraflops of power,” which is paired with a custom CPU for each Stadia rendering instance. Those instances will run on Linux and use the Vulkan API. Google has partnered with Unreal and Unity to “bring full support to the most popular and familiar game engines to our development community.”
