Vulkan Run Time Libraries, sometimes also known as Vulkan Runtime Libraries or VulkanRT, is a 3D graphics and compute API by Khronos Group.
The cross platform Vulkan API is available for Windows, Linux, and Android, and was dubbed the "next generation OpenGL" initially.
Khronos launched the Vulkan 1.0 specification on February 16th, 2016 and Khronos members released Vulkan drivers and SDKs on the same day.
Vulkan may get installed alongside video card drivers on Windows. Nvidia installs those for instance on Windows machines automatically, and does not offer options to deselect the Vulkan Run Time Libraries installation even if you select custom installation during setup of the driver.
This is also the main reason why Windows users are surprised when they see Vulkan listed under installed programs in the Start Menu, or when they open the list of installed apps or programs on Windows to uninstall some of them.
So, what is Vulkan Run Time Libraries then?
Some may fear that the Vulkan Run Time Libraries installation is malicious in nature, since they did not install the library on their own, and did not notice any of the programs that they installed doing it either.
First thing you may want to do is check whether Vulkan is installed on your computer.
If you find it listed there, Vulkan is installed, and you may wonder whether you should uninstall Vulkan.
Not all games use Vulkan, and if you are certain that none do, you may uninstall the application without any ill-effect on the system.
Games that support Vulkan include Dota 2, the latest Doom game, Star Citizen, and the Talos Principle. Also, Vulkan is support by game emulators such as the Dolphin Emulator, and by game engines such as Valve Corporation's Source 2 engine, CryEngine, Unreal Engine, Unity, and ID Tech.
Please note that you cannot install a copy of Vulkan Run Time Libraries manually after you remove the software from your operating system.
Games may refuse to run in worst case, and the only option that you have to reinstall Vulkan is to install the graphics driver again.
The main Vulkan project page links to graphics drivers for AMD, Intel, Nvidia, Qualcomm and other hardware products.
This is the only option to install Vulkan, or update it on a Windows machine. To keep it up to date, you need to install the most recent version of the graphics adapter driver that ships with Vulkan.
There you find demo and open source sample downloads as well. These may be useful to test whether Vulkan runs properly on a device.
Vulkan ships with improvements over graphics APIs such as OpenGL. Some of the most noteworthy ones are:
