What Is Vulkan?


Vulkan is a new-generation graphics and compute open standard API that provides high-efficiency, cross-platform access to modern GPUs. Created and evolved by the Khronos® Group standards consortium, Vulkan satisfies the needs of software developers in fields as varied as game, mobile and workstation application development. Vulkan's explicit API design enables efficient implementations on platforms that span a wide range of mobile, console, embedded and desktop hardware using the Windows, Linux and Android operating systems.

Why Vulkan?


Vulkan is an open standard API that the entire industry can cooperatively evolve to provide access to the latest GPU technologies. The API provides a multi-threading-centric design to leverage modern multi-core CPUs, and provide access to GPUs via multiple parallel command queues. Some of the latest Vulkan features include ray tracing, bindless resources and shader programming using GLSL or HLSL. Vulkan is not tied to a specific platform and enables developers to write GPU code that is portable to diverse devices and operating systems.



Vulkan at NVIDIA


NVIDIA provides fully conformant Vulkan 1.2 drivers across our products including Geforce and Quadro on Windows and Linux, Shield Android TV, and the range of Jetson embedded processors using Android or Linux. NVIDIA Nsight™ tools enable developers with cutting-edge Vulkan application debugging, profiling and optimization capabilities.

Vulkan is available across NVIDIA’s products


NVIDIA is deeply engaged at Khronos and the Vulkan Working Group to help drive Vulkan’s evolution through developing vendor extensions to enable developers access the very latest GPU technologies, and encouraging these capabilities to be adopted as cross-vendor Vulkan specifications at the Khronos Working Group.

To help developers get up and running quickly with Vulkan, this page contains information on NVIDIA’s Vulkan drivers, links to the full source code of educational samples and helper libraries, links the downloadable NVIDIA Nsight tools to help you debug and optimise your Vulkan code, and articles and presentations to help you learn more about what Vulkan can do for you!

NVIDIA will be regularly adding new materials on this page - so keep an eye open for the latest updates!

Vulkan Developer Tools


Nsight Aftermath

The NVIDIA Nsight Aftermath SDK is a simple library that can be integrated into a game’s crash reporter to generate GPU "mini-dumps" when a GPU hang or exception occurs.

Nsight Systems

NVIDIA Nsight Systems is a system-wide analysis tool for visualizing CPU / GPU interactions to help eliminate GPU idle, stutter and CPU bottlenecks. It can trace Vulkan on the CPU & GPU, interoperating GPU APIs, and many CPU or OS events.

RTX Ray Tracing in Vulkan

In November 2020, Khronos released the final versions of the Vulkan Ray Tracing extensions that seamlessly integrate ray tracing into the existing Vulkan framework. Vulkan is the industry’s first open, cross-vendor, cross-platform standard that can be used to access RTX ray tracing acceleration.

Alongside the release of ray tracing support in the Khronos Vulkan SDK in December 2020, NVIDIA now ships the Vulkan Ray Tracing extensions in our production Vulkan drivers . All RTX GPUs are supported, together with GeForce GTX 1660 with 6GB+ of memory and GeForce GTX 1060+ with 6GB+ of memory.

NVIDIA has also released Quake II RTX version 1.4 that uses Vulkan Ray Tracing to significantly enhance the visual quality of this well-loved classic running with ray-traced lighting, shadows, and reflections - making Quake II RTX the world’s first cross-vendor ray tracing Vulkan application! NVIDIA releases the full source code on GitHub serving as a great example for developers who want to dive into the details of how this remastering was achieved.
