Overview of new extensions in Vulkan SDK 1.2.189.0
The Vulkan headers now include the following new extensions. Note that extensions are optional and may not be implemented by the underlying driver/ICD. Applications can now query for the presence of these new features:
- VK_EXT_load_store_op_none
- VK_EXT_shader_atomic_float2
- VK_HUAWEI_persistent_thread
- VK_KHR_present_id
- VK_KHR_present_wait
- VK_NV_extermal_memory_rdma
Additional Enhancements
Here are some additional enhancements included in the new Windows, Linux, and macOS SDKs:
- The device simulation layer can now read core 1.1, core 1.2, and surface capabilities from the JSON files provided by GPUinfo.org
- The Vulkan Configurator (vkconfig) has been updated to improve quality and stability.
macOS Updates
In addition to the updates listed above, the macOS SDK now supports MoltenVK version 1.1.4 with the following highlights:
- Changes to how vkSemaphore is supported

- Fix issue with vkCmdBlitImage() from compressed textures
- Multiple fixes specific for Apple Silicon
- Update VK_MVK_MOLTENVK_SPEC_VERSION to 32
- Update to latest SPIRV-Cross version:
- MSL: Adjust gl_SampleMaskIn for sample-shading and/or fixed sample mask
- MSL: Remove redundant path for SampleMask
- MSL: Support row-major transpose when storing matrix from constant RHS matrix
