Earlier quoted context omitted.

But you have to rewrite it for every major hardware vendor, or else you won't get the performance you want. GL should always work for the simple case, but instead you need to rewrite to avoid bugs in its many layers. And once you have Vulkan/Metal, industry-specific wrappers are better than the impossible to debug procedural GL junk.

I'm not sure I agree with the claim, but even if we take a full rewrite at face value, "every major graphics vendor" for desktop applications is NVIDIA and AMD/ATI. On mobiles, you're probably using Unity or similar middleware and therefore not thinking about bare metal (no pun intended)

Ugggggh. As if graphics support on macOS weren't middling enough already. It's like they're trying to become as irrelevant as possible in that area. I could understand if they were deprecating it in favor of Vulkan. That would be in-line with Apple's history of aggressively pushing forward new standards. But by no means do they have the clout to coerce developers into their own bespoke graphics API that doesn't work…

Apple must truly hate gaming, or suffer from a serious case of Not Invented Here with their Metal stuff. As if any serious gaming studio would target Metal which doesn't run on Windows. In fact, they couldn't get their act together, keep with current versions, and as a result titles like Elite Dangerous were being shut down anyway. Reason: OpenGL stuck on an old version without support of compute shaders. https://for…

This is a problem that is entirely of Apple's own doing. Microsoft could not care less about OpenGL on Windows. However, it works just fine. You know why? As soon as you install your video card drivers, your OpenGL implementation is no longer from Microsoft. It comes from AMD, NVidia or Intel, with all needed optimizations for their hardware. Apple insisted in not allowing this and doing the OpenGL implementation the…

The classic "Fuck Off" hubris from Apple. Their B.S. is getting out of hand. List of gripes: 1. Heavy handed regulation of app store: This needs intervention from regulatory authorities. Apple has successfully inserted itself between the consumer and producer of apps. It plays kingmaker, and very clearly promotes internal apps to the competition (recent ban of the Steam app is a prime example). It's only legal recour…
