That is all wrong! it's a new graphics API renderer with a simpler, thinner driver, and efficient CPU multi-threading capabilities. Compared to DirectX or OpenGL, Vulkan has less latency and overhead, and can help your system reach new levels of performance. In simpler terms, Vulkan can help developers avoid CPU bottlenecks that limit performance, and can improve performance elsewhere, too. IT replaces both DirectX and OpenGL and will run smooth on AMD as well as nVidia cards.
