Exactly the reason why I haven't switched from OpenGL to Vulkan. Vulkan is just ridiculously overengineered. Cuda shows that allocation of GPU memory and copy from host to device can be one-liners, yet in Vulkan it's an incredible amount of boilerplate to go through. Modern Vulkan fixes a lot of issues, like getting rid of pipelines, render passes, bindings, etc., but there is still much more to fix before it's usable.
