What Is Vulkan?
Vulkan is a low level API that gives direct access of the GPU to developers who want the ultimate in control. With a simpler, thinner driver, Vulkan uses less latency and overhead than traditional OpenGL or Direct3D. Vulkan has efficient multi-threading capabilities with multi-core CPUs that keep the graphics pipeline loaded, enabling a new level of performance on existing hardware.
Vulkan is the first new generation, low-level API that is cross platform. This allows developers to create applications for a variety of PC and mobile devices and operating systems. Like OpenGL, Vulkan is an open, royalty-free standard for any platform to adopt. For developers who prefer to remain on OpenGL, NVIDIA will continue to lead OpenGL innovations.
