Support for features is reported and enabled on a per-feature basis. ifdef::VK_VERSION_1_1,VK_KHR_get_physical_device_properties2[] [NOTE] .Note ==== Features are reported via the basic slink:VkPhysicalDeviceFeatures structure, as well as the extensible structure sname:VkPhysicalDeviceFeatures2, which was added in the `apiext:VK_KHR_get_physical_device_properties2` extension and included in Vulkan 1.1.

This structure can: be added to the pname:pNext chain of the sname:VkPhysicalDeviceFeatures2 structure. ==== endif::VK_VERSION_1_1,VK_KHR_get_physical_device_properties2[] For convenience, new core versions of Vulkan may: introduce new unified feature structures for features promoted from extensions. At the same time, the extension's original feature structure (if any) is also promoted to the core API, and is an alias of the extension's structure. This results in multiple names for the same feature: in the original extension's feature structure and the promoted structure alias, in the unified feature structure. When a feature was implicitly supported and enabled in the extension, but an explicit name was added during promotion, then the extension itself acts as an alias for the feature as listed in the table below. All aliases of the same feature in the core API must: be reported consistently: either all must: be reported as supported, or none of them.
