It's fascinating that history is changing so fast now that even events of 10 years ago can be claimed to be something they weren't.
- 2013: AMD starts developing Mantle, and it is only available as part of AMD Catalyst, and only on Windows.
- 2013 (at least): Apple starts working on their own graphics API.
- June 2014: Metal 1.0 on iPhones is announced by Apple (it means it had already been in development much earlier, that's why I wrote "2013 at least" above)
- July 2014: Khronos starts work on Vulkan
- August 2014: The announcement of the Vulkan project and the call for participation.
- June 2015: Apple announced Metal on Macs.
- Sometime in 2015: AMD discontinues Mantle and donates it to Khronos.
- December 2015: Vulkan 1.0 specification announced by Khronos group
- February 2016: The full spec and SDK for Vulkan 1.0 released
So, reality: Metal had been released two years before Vulkan even had a specification.
> also well supported on Windows by GPU vendors.
Keyword: GPU vendors. Not by Microsoft.
> Vulkan is the primary rendering API on Android and Linux these days
But not on Macs, iPhones, Windows, XBox, and Playstation.
And yet, "omg why doesn't Apple support this late-to-the scene quite shitty API that it must support because we say it must".
