This is NOT an Apple hardware issue. Overwatch even supports Intel integrated graphics at the low end. People keep ignoring this fact here on purpose.
The issue is more likely related to the perceived cost vs revenue to make the OS X port and/or issues with metal and other Apple coding stuff that Blizzard feels it's not worth the time and effort to deal with. If Blizzard really wanted to deal with this, they would. They are large enough to do so.
There is nothing lackluster about it, Apple's hardware these days is just stock standard stuff. (thanks for your reply, it's honest, and your backhanded compliment is well noted). It's the drivers and other things like metal that are different. The game will perform badly on a Vista Windows machine with Intel integrated graphics also but Blizzard seems to be ok with this. That's basically saying we will allow our game to run bad on Windows but not on OS X so we will not bother to port it there at all. That's is a point I fail to understand really. Why even have the Intel Graphics as an option for a game and then not OS X. Macs have better then this level of Intel graphics.
I seriously think it's not a driver issue. That feels like a cop out excuse to me. Sony does everything proprietry for it's PS4 and the game will be ported there. I seriously think it's just a revenue issue.
Yes it is an Apple hardware issue. There's a software problem here as well, but the hardware issue is way bigger. The software issue can be fixed with... well, software. NVIDIA already offers a very good solution and I'm sure AMD will follow suit eventually if Apple does nothing. In fact, there is a beta section on AMD's site with Mac drivers (although it is extremely hard to find)
Saying it's "just a revenue issue" is meaningless. In a free market, people will buy what works best for them at their budget, ultimately. This means that a gamer isn't going to go for Macs because of poor hardware and outdated drivers, and that is what makes Mac gaming unprofitable. It's not unprofitable because it's unprofitable because it's just unprofitable because reasons.
While it's true that most Macs will technically be able to start Overwatch up, they will all run it at approx. 720p, 30 FPS, minimum settings. For a shooter, this is an absolutely terrible experience. More than likely, the game won't be properly playable unless you're on an iMac or Mac Pro, and that market is only a tiny fraction of the Mac market.
Of the current Mac lineup, only the most expensive MacBook Pro, the 5K iMac, and the Mac Pro are capable of running the game at higher than minimum settings without it turning into a slideshow. None of those machines will run it well on maximum settings at native resolion except the Mac Pro, and that's naturally because the Mac Pro doesn't have a native resolution. If you slap a 5K or even 4K display on it, it can't run Overwatch on higher than Medium or so, either.
There simply isn't enough compute power.
However, slap OS X onto my PC (which is possible thanks to the Hackintosh community) and everything runs perfectly fine. Just install the web drivers, and you actually get the best version of Middle Earth: Shadow of Mordor without a shadow of a doubt, for example. Not only does it run faster than on Windows except for SLI, but it has native support for other controller symbols (including PS4 symbols if you have a DS4) and it runs without a hitch.
So OS X + PC hardware = fine gaming experience, but OS X + Mac hardware = terrible gaming experience. How is this not a hardware issue again?
