Bill Hollings has announced the release of the MoltenVK Vulkan SDK 1.3.275 after two release candidates.





MoltenVK Vulkan SDK 1.3.275

  • Add support for extensions:
    • VK_KHR_calibrated_timestamp
    • VK_KHR_format_feature_flags2
    • VK_KHR_vertex_attribute_divisor
    • VK_EXT_extended_dynamic_state3 (Metal does not support VK_POLYGON_MODE_POINT)
    • VK_EXT_headless_surface
    • VK_EXT_layer_settings
  • Add support for format VK_FORMAT_B4G4R4A4_UNORM_PACK16.
  • Add support for vertex formats VK_FORMAT_B10G11R11_UFLOAT_PACK32 & VK_FORMAT_E5B9G9R9_UFLOAT_PACK32.
  • Fix regression that broke VK_POLYGON_MODE_LINE.
  • Fix regression in marking rendering state dirty after vkCmdClearAttachments().
  • Fix regression error in argument buffer runtime arrays.
  • Fix rare deadlock during launch via dlopen().
  • Fix initial value of VkPhysicalDeviceLimits::timestampPeriod on non-Apple Silicon GPUs.
  • Fix swapchain and surface bugs when windowing system is accessed from off the main thread.
  • Fix system memory size of tvOS.
  • Fix heapUsage query for non-unified memory devices.
  • Add a defensive guard to ensure heapUsage[0] calculation is correct.
  • Clamp max per-set descriptor limit to minimum 1024.
  • Enable the cube texture gradient workaround for Apple Silicon.
  • Ensure lineWidthGranularity is zero if the wideLines feature isn't supported.
  • Ensure maxDrawIndexedIndexValue set to UINT32_MAX.
  • Ignore no external handle types specified for buffers and images.
  • Expose VK_EXT_debug_utils device functions as device functions, not instance functions.
  • Emit primitiveRestartEnable disabled warning only for strip topology.
  • Enable mandatory VK_EXT_descriptor_indexing features, and don't advertise extension if they are not supported.
  • Reduce disk space consumed after running fetchDependencies script by removing intermediate file caches.
  • Deprecate vkSetMoltenVKConfigurationMVK().
  • Deprecate mvk_config.h and move content to mvk_private_api.h and mvk_deprecated_api.h.
  • The Cube demo is now based on Volk, with dynamic library linking, and dynamic function pointer calls.
  • Update copyright notices to year 2024.
  • Update dependency libraries to match Vulkan SDK 1.3.275.
  • Update to latest SPIRV-Cross:
    • MSL: Fix regression error in argument buffer runtime arrays.
    • MSL: Work around broken cube texture gradients on Apple Silicon.
    • MSL: Ensure discrete runtime arrays of buffers have known length.
    • MSL: Implement Metal 3.1 image atomics natively.
    • MSL: Fix patch vertex count with raw buffer tese input.
    • MSL: Improve handling of sample masks.
    • MSL: Add divide to reserved function names.
    • MSL: Support std140 half matrices and arrays.
    • MSL: Use more appropriate padded types.
    • MSL: Don't use swizzle if we have wrapper.
    • MSL: Add ray-cull mask
    • MSL: Consider PtrAccessChain on array types.
    • MSL: Use LHS expression to determine whether or not to do array copy.
    • MSL: Only do address-of expression when needed.
    • MSL: Improve PtrAccessChain handling.
    • MSL: Use powr instead of pow.
    • MSL: Remove special case for threadgroup array wrapper.
    • MSL: Added an Op field to SPIRType and refactor.
