Bill Hollings has announced the release of MoltenVK Vulkan SDK 1.3.204.



Vulkan SDK 1.3.204

MoltenVK is a driver-level implementation of the Vulkan 1.0 graphics and compute API, that runs on Apple's Metal graphics and compute framework on both iOS and macOS.

MoltenVK allows you to use the Vulkan graphics and compute API to develop modern, cross-platform, high-performance graphical games and applications, and to run them across many platforms, including both iOS and macOS.

  • Add MVK_HIDE_VULKAN_SYMBOLS env var to support building MoltenVK with static Vulkan linkage symbols hidden.
  • Improve accuracy of VkPhysicalDeviceLimits::timestampPeriod.
  • Do not use MTLEvent for VkSemaphore under Rosetta2.
  • On Apple Silicon (iOS, tvOS & macOS), set VkPhysicalDeviceProperties::deviceID from GPU capabilities.
  • Support compiling MSL 2.4 in runtime pipelines and MoltenVKShaderConverterTool.
  • Fix issue where MSL 2.3 only available on Apple Silicon, even on macOS.
  • Fix memory leak of dummy MTLTexture in render subpasses that use no attachments.
  • Fix Metal object retain-release errors in assignment operators.
  • Fix use of GPU counter sets on older versions of iOS running on the simulator.
  • mvk::getShaderOutputs() in SPRIVReflection.h support flattening nested structures.
  • Replaced ASL logging levels with MVKConfigLogLevel.
  • MoltenVKShaderConverter tool support loading tessellation shader files.
  • MoltenVKShaderConverter tool update to MSL 2.4 by default.
  • Upgrade to Vulkan 1.3 headers.
  • Update VK_MVK_MOLTENVK_SPEC_VERSION to version 33.
  • Update copyright notices to year 2022.
  • Update to latest SPIRV-Cross:
    • MSL: Add 64 bit support for OpSwitch.
    • MSL: Don't output depth and stencil values with explicit early fragment tests.
    • MSL: Fix incorrect MSL gl_TessCoord variable type.
    • MSL: Allow copy array from UniformConstant storage.
    • MSL: Handle signed atomic min/max.
    • Fix normalize on half3/half2.
    • MSL: Handle constant construct of block-like array types.
    • MSL: Rethink how opaque descriptors are passed to leaf functions.
    • Rework how loop iteration counts are validated.
    • Clamp vector element access to vector size.
    • Handle aliased names in spec constants.
    • Add support for LocalSizeId.
