Microsoft doesn't support Vulkan or OpenGL, yet they also are not blocking them. That's the critical difference here. It's not a question of not supporting it out of the box or doing the work, it's a question of preventing others from supporting it. They did so because they were in a highly competitive marketplace and supporting OpenGL was a competitive advantage. Meanwhile, on the Mac, the cheese grater Mac Pro is the only model you can install their graphics cards into and it exited production half a decade ago.
The question is why should Nvidia or ATI take on the expense when there is no marketplace to compete in. They both have competitive Linux drivers which has even less market share. Given how little kernel-specific is even in the driver I don't see any reason to believe Nvidia or AMD wouldn't happily provide their latest and greatest driver.
Especially since they are competing for that bid for whose GPU Apple blesses for that generation of Mac hardware. You can buy their graphics cards and plug them into a computer running Linux, say in a render farm. The only Mac you can purchase and use their products in exited production half a decade ago. Without the possibility of making sales, why would they bother?
Apple's pro software made a big bet on OpenCL in the past, so I don't see them going with anybody but ATI for built in GPUs until they root that dependency out of their software and switch over to Metal for compute. OpenCL performs great on Nvidia.
That happens to be not terribly long after Apple started offering rewrites of their pro apps that went all in on OpenCL. Nvidia did put out a driver for the cheese grater Mac pro so it can use Pascal based cards, which is nice, but I imagine that's motivated by a desire to maintain CUDA dominance. Market share for Metal is an order of magnitude less than for DirectX.

That's a hurdle. Windows PC shipments in seem to be about million https: The total market share is a much more complicated picture, obviously, but I don't think the difference is nearly as big as you do. It also depends on what exactly Gartner classified as "Ultramobile Premium ", which they apparently counted towards the "Total PC market" million in Which one comes out ahead depends on the relative share of Windows 10 tablets vs. In any case, that still puts Metal and DirectX in the same order of magnitude.
Keep in mind that Metal also works on iOS. That's probably a good question. Those who are actually pushing the hardware in both camps are most likely the minority, as opposed to those who are working with glorified web views. This list[1] is quite a bit different looking from this list[2] [1] http: Get it right Over a billion iPhones have been sold, and a couple billion Windows PCs. Not quite "two orders of magnitude". Are you so sure about your numbers there? What's your evidence? Their real leverage is iOS, which lots of games want to target.
They want to control the APIs so they can tie them more closely to their hardware. Even giving metal a few years of development it still means Apple abandoned OSX graphics before they began working on Metal at all. I'm sure the real reason is a combination of these factors. For comparison the Vulkan project began July and was released 19 months later. So let's say Metal took 2 years from conception to release, even though it only targeted one platform and one GPU and likely took less time as a result That means OpenGL was abandoned on OSX roughly 3 years before Metal existed as a project at all.
The timelines of Metal vs. It just doesn't mesh. I don't know the timeline that the graphics team at Apple follows, so the best I can provide you with is a guess as to what I think the reasons are behind their release schedule. Maybe the team was reorganized? Because current projects must work? And they'll continue to work if nobody changes them.

MBCook 11 months ago. Why would you want a newer OpenGL? I thought the whole point of Vulkan, DX12, and Metal was to move away from such a single-threaded stack driven graphics API to something that was a much better fit for modern cards and engines. It's old enough to not even have compute shaders that's OpenGL 4. How do you prevent shaders being used to gain elevated privileges?
How can I use OpenGL 4.3?
By not having buggy drivers? It's a large attack surface which has received relatively little attention from hackers so far compared to CPUs, but there are hardware-level security features in place. It's a really small attack surface. There's no OS to speak of, no privileged processes to poke at, etc Other than the framebuffer there's not even any data of worth on the GPU. The attack of note that's been mitigated is DoS attacks through webgl, but GPU preemption is a thing now which largely solves the infinite loop in a shader to lock up the machine.
Sorry but you are really on the wrong track on every point.

And re the MMU features upthread, it's just a building block. You seem to have entirely lost the context. We're talking what you can attack from code running on the GPU aka, from a compute shader , which does not include the drivers since that's not running on the GPU. If you want to attack the shader compiler go for it, but since that lives in your own process anyway so you could skip that step and go straight to attacking whatever it is you wanted to attack. Such as? All I'm finding are DoS attacks. The context was "How do you prevent shaders being used to gain elevated privileges?
Regarding WebGL vulnerabilities, you can use your favourite search engine to look up vulnerabilities, here are some first hits for RCE bugs: HN, what I largely assume is a community of programmers. Not Khronos idealists. The OpenGL dream died long ago. Yet here we are again. Not porting over Vulkan or OpenGL. Just use Metal. It really is, very good.

Vulkan is also very good, and not vendor locked. Vulkan is the sole ray of hope that one day we may have a sane graphics stack that works properly across different platforms. If I'm reading the trend right I might even be able to get rid of my Windows partition during my lifetime. It won't be because Apple decided to make it's own competing standard. It's not just Apple. This is what everyone forgets. It's Microsoft, Apple, Sony and Nintendo.
Idealism is not the answer to positive end user experience. It's not the creation of a committee catering to the lowest common denominator. Games use it, too. Increasingly more of them use it than they used to, even, as increasingly games are using off-the-shelf engines that are already cross-platform and have an OpenGL back-end. LeoNatan25 11 months ago. Most mobile users who matter revenue.
Revenue per graphics API would be fascinating, albeit very different, investigation. It would likely also put OpenGL on desktop in a very different light given the professional products still using it.
