    Khronos Updates Vulkan to 1.0.43 Spec


    • Posted By khawk

    The Khronos Group updated the Vulkan 1.0 API specification with two new extensions and updates for clarifications in the documentation and other minor behavior differences.

    The two extensions include VK_EXT_hdr_metadata and VK_GOOGLE_display_timing.

    VK_EXT_hdr_metadata is a renaming of the VK_EXT_SMPTE2086_metadata extension, which supports SMPTE 2086 meta-data in the swapchain. The new extension furthers this by also including CTA 861.3 meta-data support, which improves Vulkan's HDR support.

    VK_GOOGLE_display_timing allows applications using VK_KHR_swapchain to retrieve information about the presentation engine's display, obtain timing information about each present, and to schedule a present to happen no earlier than a desired time. Developers can use this to minimize stuttering and other anomalies.
