Members

---

• property_type specifies the type of the queried property. must be WisQueryPropertyType..
• next_in_chain indicates pointer to the next queried data struct.
• supported_queues describes an array of supported queue types. If a queue type is supported, the value is 1, otherwise 0. Order of queue types is the same as in WisCommandQueueType enum.
• relaxed_queue_transition indicates if relaxed queue transition is supported. This feature allows executing command lists that contain buffers used on different queue types without explicit resource state transitions when the buffers is used on a different queue type. It is supported on Windows 10 22H2 and later with WDDM 3.0 or later. On Vulkan it requires VK_KHR_maintenance9 extension.
• max_queue_priority indicates an array of maximum supported priorities for each queue type. If a queue type is not supported, the value is 0. Order of queue types is the same as in WisCommandQueueType enum.
