Does anyone have any experience with Metal or Vulkan ?

Answer 1

Just a note on the subject - today (Sep 12, 2018) there is a free 700-page ebook on Vulkan (with a code pack included) at:

Answer 2

I have never written Metal or Vulkan, but here is what I know:

Metal is Apple-specific, Vulkan is supported by several platforms.

Metal would probably run faster on Apple devices, but Vulkan can run on more devices.

Vulkan is supposed to be the "next OpenGL", but It hasn't been around and refined as much as OpenGL has.

I personally use OpenGL because of its cross-platform nature and simplicity.

In conclusion:

If you want to be stuck to Apple, use Metal. Otherwise use Vulkan. (Or OpenGL hehe)

I hope I helped a little bit...
