在 MoltenVK 中启用实例扩展
Enable instance extensions in MoltenVK
我想使用 MoltenVK 1.0.38 中支持的扩展，目前有 47 个在您初始化 Vulkan 实例时打印。有趣的是，当我调用 vkEnumerateInstanceExtensionProperties 时，我只得到其中的 9 个：
VK_KHR_device_group_creation
VK_KHR_get_physical_device_properties2
VK_KHR_get_surface_capabilities2
VK_KHR_surface
VK_EXT_debug_report
VK_EXT_debug_utils
VK_EXT_metal_surface
VK_EXT_swapchain_colorspace
VK_MVK_macos_surface
我对 VK_EXT_hdr_metadata 特别感兴趣，但这个列表中没有。以下是 MoltenVK 表示支持但我不可用的受支持扩展的完整列表：
