Ah you are right, I forgot that they both were announced at around the same time. It just feels like Vulkan took forever. To the point where some teams at my job had to use OpenGL even for greenfield projects for quite a while after Vulkan was first announced (even when they wanted to use Vulkan).

I wonder if that means that dx12 and Vulkan could have a good interop/compatibility story, since they both have similar origins.
