# VkPhysicalDevicePerformanceQueryPropertiesKHR(3) Manual Page

## Name

VkPhysicalDevicePerformanceQueryPropertiesKHR - Structure describing performance query properties for an implementation

## C Specification

The `VkPhysicalDevicePerformanceQueryPropertiesKHR` structure is defined as:

    typedef struct VkPhysicalDevicePerformanceQueryPropertiesKHR {
        VkStructureType    sType;
        void*              pNext;
        VkBool32           allowCommandBufferQueryCopies;
    } VkPhysicalDevicePerformanceQueryPropertiesKHR;

## Members

The members of the `VkPhysicalDevicePerformanceQueryPropertiesKHR` structure describe the following implementation-dependent properties:

## Description

- `sType` is the type of this structure.

- `pNext` is `NULL` or a pointer to an extension-specific structure.

- `allowCommandBufferQueryCopies` is `VK_TRUE` if the performance query pools are allowed to be used with vkCmdCopyQueryPoolResults.

Valid Usage (Implicit)

- `sType` must be `VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_PERFORMANCE_QUERY_PROPERTIES_KHR`

If the `VkPhysicalDevicePerformanceQueryPropertiesKHR` structure is included in the `pNext` chain of VkPhysicalDeviceProperties2, it is filled with the implementation-dependent properties.
