How Vulkan Enables High-Performance Real-Time 3D Graphics Applications



Vulkan: A Modern Graphics and Compute API for High-Performance Applications




Vulkan is a low-overhead, cross-platform API, open standard for 3D graphics and computing. It targets high-performance real-time 3D-graphics applications, such as video games and interactive media, and highly parallelized computing. Vulkan is intended to offer higher performance and more efficient CPU and GPU usage compared to the older OpenGL and Direct3D 11 APIs. It does so by providing a considerably lower-level API for the application than the older APIs that more closely resembles how modern GPUs work. Vulkan is comparable to Apple's Metal API and Microsoft's Direct3D 12, and is harder to use than the higher-level OpenGL and Direct3D 11 APIs. In addition to its lower CPU usage, Vulkan is designed to allow developers to better distribute work among multiple CPU cores.


History of Vulkan




Vulkan was first announced by the non-profit Khronos Group at GDC 2015. The Vulkan API was initially referred to as the "next generation OpenGL initiative", or "OpenGL next" by Khronos, but use of those names was discontinued when "Vulkan" was announced. Vulkan is derived from and built upon components of AMD's Mantle API, which was donated by AMD to Khronos with the intent of giving Khronos a foundation on which to begin developing a low-level API that they could standardize across the industry.

Features of Vulkan




Vulkan is intended to provide a variety of advantages over other APIs as well as its predecessor, OpenGL. Vulkan offers lower overhead, more direct control over the GPU, and lower CPU usage. The overall concept and feature set of Vulkan is similar to concepts seen in Mantle and later adopted by Microsoft with Direct3D 12 and Apple with Metal. Intended advantages of Vulkan over previous-generation APIs include the following:


  • Unified API: Vulkan provides a single API for both desktop and mobile graphics devices, whereas previously these were split between OpenGL and OpenGL ES respectively.



  • Cross platform: Vulkan is available on multiple modern operating systems. Like OpenGL, and in contrast to Direct3D 12, the Vulkan API is not locked to a single OS or device form factor. Vulkan runs natively on Android, Linux, BSD Unix, QNX, Haiku, Nintendo Switch , Raspberry Pi, Stadia, Fuchsia, Tizen, and Windows 7, 8, 10, and 11.



  • Explicit control: Vulkan gives developers more control over the GPU pipeline, memory management, synchronization, threading, and resource allocation. This allows for more fine-grained optimization and reduced CPU overhead.



  • Modern features: Vulkan supports the latest graphics technologies such as ray tracing, variable rate shading, mesh shaders, bindless resources, dynamic state descriptors, timeline semaphores, subgroup operations, shader interlock, subgroup ballot extensions etc.



  • Extensibility: Vulkan has a modular design that allows for extensions to add new features and capabilities without breaking backward compatibility. Extensions can be vendor-specific or standardized by Khronos.



Examples of Vulkan




Vulkan has been adopted by many games and applications that benefit from its performance and flexibility. Some examples are:


  • The Talos Principle: One of the first games to support Vulkan on Windows and Linux. It showed significant performance improvements over OpenGL on both platforms.



  • Doom (2016): One of the first AAA games to use Vulkan on Windows. It achieved higher frame rates and smoother gameplay than Direct3D 11 on both AMD and NVIDIA GPUs.



  • Wolfenstein II: The New Colossus: The first game to use Vulkan exclusively on Windows. It also supported NVIDIA's adaptive shading technology for dynamic resolution scaling.



Examples of Vulkan (continued)




  • No Man's Sky: A game that uses procedural generation to create a vast universe of planets, stars, and lifeforms. It switched from OpenGL to Vulkan on Windows and Linux, resulting in improved performance, stability, and compatibility.



  • Red Dead Redemption 2: A critically acclaimed open-world game that features a detailed and realistic depiction of the American frontier. It uses Vulkan on Windows to deliver stunning graphics and smooth gameplay.



  • Quake II RTX: A remastered version of the classic first-person shooter that uses ray tracing to enhance the lighting and shadows. It uses Vulkan to enable ray tracing on NVIDIA RTX GPUs.



Conclusion




Vulkan is a modern graphics and compute API that offers many benefits for developers and users of high-performance applications. Vulkan enables more efficient CPU and GPU usage, lower overhead, more direct control over the hardware, and support for the latest graphics technologies. Vulkan is also cross-platform and extensible, making it a versatile and future-proof API. Vulkan is not without its challenges, however. Vulkan requires more knowledge and effort from developers than higher-level APIs, and it may not be compatible with some older hardware or software. Vulkan also faces competition from other APIs such as Metal and Direct3D 12, which may have more support or features on certain platforms or devices. Despite these challenges, Vulkan has proven to be a powerful and popular API for many games and applications, and it is likely to continue to grow and evolve in the future.


FAQs




What does Vulkan mean?




Vulkan is a word derived from the name of a Roman god of fire, volcanoes, and metalworking. It also refers to a fictional alien species in the Star Trek universe. The name was chosen by Khronos to reflect the power and performance of the API.

How do I use Vulkan?




To use Vulkan, you need a device that supports the API, such as a modern GPU or smartphone. You also need a driver that implements the API for your device. You can check if your device supports Vulkan by using tools such as GPU-Z or Vulkan Caps Viewer. To develop applications that use Vulkan, you need a SDK (software development kit) that provides libraries, tools, and documentation for the API. You can download the official Vulkan SDK from LunarG or use other SDKs such as Google's Android NDK or NVIDIA's GameWorks SDK.


What are the differences between Vulkan and OpenGL?




Vulkan and OpenGL are both graphics APIs developed by Khronos, but they have different design goals and features. OpenGL is a higher-level API that abstracts away many details of the hardware and provides a simpler interface for developers. OpenGL is easier to use than Vulkan, but it also has more overhead and less control over the hardware. Vulkan is a lower-level API that exposes more details of the hardware and provides more control over the GPU pipeline, memory management, synchronization, threading, and resource allocation. Vulkan is harder to use than OpenGL, but it also offers higher performance and more efficient CPU and GPU usage.


Is Vulkan better than Direct3D 12 or Metal?




Vulkan is not necessarily better or worse than Direct3D 12 or Metal, but it has different strengths and weaknesses compared to them. Direct3D 12 is a low-level graphics API developed by Microsoft for Windows 10 and Xbox One devices. It has similar features and capabilities as Vulkan, but it is not cross-platform or open standard. Metal is a low-level graphics API developed by Apple for iOS, macOS, tvOS, and watchOS devices. It has some features that are not available in Vulkan, such as tessellation shaders and geometry shaders, but it also lacks some features that are available in Vulkan, such as ray tracing and variable rate shading. The choice of which API to use depends on factors such as the target platform, device compatibility, developer preference, performance requirements, etc.
