Forsaken Remastered was just updated with Vulkan support! If you're on Linux, you're probably hitting 60fps with the existing OpenGL renderer, but it's good to be future proof. If you're on a Mac, though, you definitely want to switch. On my MacBook, the framerate goes from around 15 to a solid 60! On macOS, Vulkan support is supplied by MoltenVK, which we now ship with the game. It should work on any Mac that supports Apple's Metal API, which MoltenVK uses to make Vulkan work. You can change from OpenGL to Vulkan in-game in the "Video" options menu.
MoltenVK 1.0.20 is out as the latest feature update to this Vulkan-over-Metal layer. With the MoltenVK 1.0.20 release there is support for several new extensions including VK_KHR_maintenance1, VK_KHR_shader_draw_parameters, VK_KHR_get_physical_device_properties2, and VK_KHR_push_descriptor. MoltenVK 1.0.20 also adds the ability to track and access supported/enabled extensions and has re-based its SPIRV-Cross code against upstream.
Earlier this month there was a report on a game studio finding their MoltenVK-using game rejected from Apple's App Store. The situation is now resolved and Apple has allowed this Vulkan-over-Metal game into their iOS marketplace. Details on the issue and how it was resolved are set out in this Phoronix story.
A new pull request has been submitted to MoltenVK, the open-source project for mapping the Vulkan graphics/compute API over Apple's Metal to run on iOS/macOS. This pull request is working to address the issue that caused at least one MoltenVK-using iPhone/iPad game to be rejected from the Apple App Store.
The QtBase dev branch, which will become Qt 5.12, now has experimental Vulkan support, courtesy of MoltenVK and prior work in Qt. When the MoltenVK Vulkan to Metal translation library was open sourced earlier this year, this opened the question of how to make this work with Qt. Check out the Qt blog to learn how support for MoltenVK was accomplished.
Yesterday Valve released Vulkan support for Dota 2 on macOS. Indeed, this first major game relying upon MoltenVK for mapping Vulkan over the Apple Metal drivers is delivering performance gains. Phoronix has started to post some benchmarks.
The Khronos Group announces that the Vulkan Working Group’s Portability Initiative has been working with Khronos members Valve, LunarG, and The Brenwill Workshop to enable Vulkan applications to be ported to Apple platforms. The Vulkan Portability resource page links to a collection of free and open source set of tools, SDKs, and runtime libraries to enable Vulkan development on macOS and deployment on macOS and iOS platforms. Valve is extending Dota 2 using the Vulkan tools on macOS to achieve significantly higher performance than native OpenGL drivers. Vulkan support for Dota 2 on macOS will be released in the coming months as a free update.
