Mantle was released ~1 year before Metal.

Proprietary to AMD, which gave it to Khronos when it was obvious they would do a second version of Longs Peak if left on their own.

Yet Vulkan, shows they cannot fix their love for extensions spaghetti.

DirectX was released a decade before Vulkan, that didn't stop manufacturers from including support for both so the user could decide for themselves.

You mean the support that is only possible because Windows backward compatibility still supports the OpenGL 1.1 ICD that they rely on?

Most of the time with crappy drivers that are a shadow of their DirectX ones?

> still supports the OpenGL 1.1 ICD that they rely on?

On Windows 11, it’s OpenGL 3.3 on top of DX12, because Qualcomm doesn’t provide an OpenGL ICD at all.

> crappy drivers

Special mention to the Intel OpenGL graphics driver on Windows. If you thought that the AMD Windows one was bad, the Intel one was somehow significantly worse.

With this gpu performance you’d think Apple might like to take advantage for gaming.

They already do, all middleware engines that actually matter, already support Metal.

Additionally iOS and Apple have much better tooling for Metal than plain DirectXTK/Pix, or that toy SDK from Khronos (that Google also uses on Android), if we compare vendor tooling.

Sounds like you don't need any help then, enjoy your 50-75% performance hit playing (a scant few) games through DirectX -> Vulkan -> Wine/Crossover ($30) -> MoltenVK -> Metal!

The games I care about enjoy native Metal and DirectX, and when I code anything graphics I don't use Khronos stuff, only on the Web, where there is no other option.

Any game dev gems have basic examples on doing an API loading layer.

Vulkan is mostly a Linux thing, and even the Switch has its own native API, NVN, it is not Vulkan nor OpenGL on the driving seat.

That’s not shown in terms of games people actually want to buy.
