Bill Hollings has announced the release of the MoltenVK Vulkan SDK 1.3.261 RC2.



Release Release for Vulkan SDK 1.3.261 (RC2)

  • Add support for extensions:
    • VK_KHR_incremental_present
    • VK_KHR_shader_non_semantic_info
    • VK_EXT_4444_formats
    • VK_EXT_calibrated_timestamps
    • VK_EXT_pipeline_creation_feedback
    • VK_EXT_shader_demote_to_helper_invocation
    • VK_EXT_shader_subgroup_ballot
    • VK_EXT_shader_subgroup_vote
  • Add support for VK_PRIMITIVE_TOPOLOGY_TRIANGLE_FAN.
  • Support building MoltenVK for visionOS.
  • Ensure non-dispatch compute commands don't interfere with compute encoding state used by dispatch commands.
  • Support maximizing the concurrent executing compilation tasks via MVKConfiguration::shouldMaximizeConcurrentCompilation
  • Support VK_PRESENT_MODE_IMMEDIATE_KHR if VkPresentTimeGOOGLE::desiredPresentTime is zero.
  • Add support for VK_PRESENT_MODE_IMMEDIATE_KHR to macOS Cube demo.
  • Allow both renderPass and VkPipelineRenderingCreateInfo to be missing.
  • Fix sync delay between calls to vkQueueSubmit() on non-Apple-Silicon devices.
  • Ensure Xcode simulator always uses 256B buffer alignment.
  • Don't attempt to force the window system to use the same high-power GPU as the app, on every swapchain creation.
  • Log more info about SPIR-V to MSL conversion errors.
  • Implement Deferred Host Operations.
  • Support MSL Version 3.1.
  • Drop official support for using Xcode 11 to build MoltenVK.
  • To allow building MoltenVK without an internet connection, don't fetch a submodule if the commit is already known.
  • Update dependency libraries to match Vulkan SDK 1.3.261.
  • Update to latest SPIRV-Cross:
    • MSL: Fix argument buffer padding when content includes arrays.
    • MSL: ray-query intersection params
    • MSL: Support SPV_KHR_shader_ballot and SPV_KHR_subgroup_vote.
    • Skip line directives when emitting loop condition blocks.
    • MSL: Consider changed array types for array-of-constant-bool in struct.
    • MSL: Consider bool-short remapping for constant expressions as well.
    • Minor cleanup in constant_expression().
    • MSL: Add test for bool-in-struct edge cases.
    • MSL: Handle more complex array copy scenarios with bool <-> short.
    • MSL: Handle stores to struct bool[].
    • MSL: Consider bool/short remapping when dealing with composites.
    • MSL: fix function constant deduplication misfire
