Oct 02, 2015 Tech — Metal performance in OS X El Capitan: Sometimes great, often mixed Updated As with DirectX 12, results vary from test to test and GPU to GPU. 30 rows Jun 12, 2018 Metal is finally delivering on its promise of improved graphics performance for Mac gamers, and game developers seem all on board. The result: an avalanche of Metal MacOS games.

The Brenwill Workshop is the development company behind the MoltenVK API, claiming game developers who use the set of routines will gain the debugging and variable performance tuning benefits of Apple's Metal, in addition to the speed benefits and high performance of Vulkan.
Vulkan is an open standard, developed by the Khronos Group, an industry consortium dedicated to the creation of open standards for the graphics industry. The OpenGL and OpenCL standards, heavily used by Apple, are maintained by the Khronos Group.

One of the biggest historical obstacles to porting games to macOS has been Microsoft's ubiquitous DirectX graphics API. Developers need to translate the original DirectX calls into OpenGL, OpenCL, or Metal, adding to the complexity of migrating code which can already be hundreds of thousands of lines long.
For now, Vulkan has only been implemented in games and the underlying engines that render the environments. The new Doom

, for example uses the API. Popular game engines Serious Engine 4
by Croteam, and the more widely used Unreal Engine 4 by Epic Games have Vulkan support.Android 7.0 Nougat is also expected to natively support Vulkan for speedier overall rendering on compatible Android hardware.

Vulkan leverages better utilization of multiple core CPUs, as found on every Mac, as well as better execution of GPU hardware-specific routines. Doom benchmarkers are seeing a 30 to 40 percent increase in game performance with Radeon cards on the title. Additionally, the Doom lead rendering programmer is also reporting efficiency improvements of between three and five milliseconds per frame —significant, since a frame must be rendered for the game in 16 milliseconds or less.Metal On Mac Os Games Download

While Apple is among the members in the Khronos Group, Apple has not as of yet released its own support for the API in either iOS or macOS. Initial specifications from the Vulkan release in January of 2016 state that Vulkan will work on hardware that currently supports OpenGL ES 3.1 or OpenGL 4.0.
