To elaborate on this, Vulkan is an open _standard_ whose many implementations (user mode driver) may or may not be open source. Vulkan is just a header file, it's up to the various independent hardware vendors (IHVs) to implement it for their platform.

Also a small correction: Vulkan actually _does_ run Apple platforms (via Vulkan-to-Metal translation) using MoltenVK and the new KosmicKrisp driver, and it works quite well.

> Vulkan is an open _standard_

That too kinda depends on where you draw the line, the spec text is freely available but all development happens behind closed doors under strict NDA. From an outsiders perspective it doesn't feel very open to get completely stonewalled by Khronos on the status of a feature that debuted in DirectX or CUDA well over a year ago, they won't even confirm whether it's on their roadmap.

		Sure, that's true and a pretty valid criticism of the system. My definition of open is that Khronos doesn't restrict (as far as I know) what platforms Vulkan can be implemented on. The same cannot be said for DX12 or Metal.

I think, since they mentioned some enterprise deployments on Windows won't have Vulkan drivers preinstalled, that drivers merely being available is not enough for GP to count them as Vulkan "running". I think GP is only counting platforms (and circumstances) where you can reasonably expect Vulkan support to already be present.

		Fair enough! In my humble opinion those specific circumstances outlined are a bit overly-pedantic for the target audience of this article and for general practical purposes. The average Windows user can reasonably expect that they'll be able to write a Vulkan application without much fuss ( until you run into the driver bugs of course ;) ).
