Vulkan Runtime Libraries (often shortened to VulkanRT) is a cross-platform 3D graphics and compute API maintained by the Khronos Group. Think of it as a modern, powerful cousin to older standards like OpenGL and a direct competitor to Microsoft's DirectX 12.
Unlike older, heavier graphics protocols like OpenGL, Vulkan is a "close-to-metal" API. This means it drastically reduces driver overhead by allowing software to talk directly to your Graphics Processing Unit (GPU). Vulkan Runtime Packaging on Windows NT Systems vulkanrt111080installer work
