Pojavio mi se prošli tjedan na downloadu DP nove verzije OSX-a, El Capitan.

Uz manje kozmetičke promjene i peglanje Yousemita, najvažnija promjena je Metal, novi grafički API koji bi trebao omogućiti značajni pomak u performansama zahtjevnijih igri i pro grafičkih alata, a koji je do sada u malo drugačijoj formi bio dostupan na iOS platformi:

Metal for Mac: Metal for Mac has arrived, combining the computing power of OpenCL and graphics power of OpenGL into a new API that does both. 50% improvements in rendering with 40% less CPU processing power required for graphics. Metal on OS X El Capitan offers better battery life and improved graphics performance for both games and professional apps.

Malo više o novom API:

Showcasing Epic's forthcoming game Fortnite, a few developers from the well-known game studio showcased how the graphics engine will be perfect for high performance games, combining the computing power of OpenCL and graphics power of OpenGL into new API that does both. With Metal, Apple machines will be able to accelerate Core Animation and Core Graphics, boosting system-level rendering by up to 50 percent, and efficiency by up to 40 percent. Specifically for higher-end games, however, Metal will take full advantage of a Mac's CPU and GPU, delivering "up to ten times faster draw cell performance," for a richer gaming experience.

OS X’s Metal will be going head-to-head with Microsoft’s DirectX 12 and Khronos’s Vulkan, and this is the first time in a very long that we have seen a viable and competitive 3rd graphics API on the desktop, as DirectX and OpenGL have been the reigning APIs since the turn of the millennium.

As for what this means for Mac users, in the short run it’s a good thing. With Vulkan still in development, had Apple not implemented Metal on OS X, OS X would have needed to stick with classic OpenGL for another year until OS X 10.12. Going with their own API, as was the case with mobile, gets a low-level API on OS X sooner. Furthermore because it’s been on iOS for the last year, Apple gets to leverage all of the developer experience and code already written for Metal, and bring that over to OS X. Which is why developers like Epic are able to show off engines using Metal on OS X so early.

In the long run however there are some big unknowns left to answer, which could have a big impact on how things play out. Apple has not yet released the complete documentation for the newest version of Metal – specifically, we don’t have feature lists – so how the Mac and iOS versions compare feature-wise remains to be seen. My biggest concern here is that Apple will put OS X and iOS at parity, essentially limiting the features available to the lowest common denominator of iOS, leading to Macs in general being behind the curve in graphics features. The other big question is whether Apple will support Vulkan next year once it’s done, or whether they will stick with Metal, essentially turning OS X’s graphics stack proprietary. Which for users could lead to a reduction in game ports to the Mac if developers have to go write against a Mac-specific graphics API.

Ako ulovim vremena mogao bih isprobati DP1 slijedeći tjedan.
