public class VkPhysicalDevicePerformanceQueryFeaturesKHR
extends org.lwjgl.system.Struct
implements org.lwjgl.system.NativeResource
```
Structure describing performance query support for an implementation.
Description

If the VkPhysicalDevicePerformanceQueryFeaturesKHR structure is included in the pNext chain of the VkPhysicalDeviceFeatures2 structure passed to GetPhysicalDeviceFeatures2, it is filled in to indicate whether each corresponding feature is supported. VkPhysicalDevicePerformanceQueryFeaturesKHR can also be used in the pNext chain of VkDeviceCreateInfo to selectively enable these features.

Valid Usage (Implicit)
- sType must be STRUCTURE_TYPE_PHYSICAL_DEVICE_PERFORMANCE_QUERY_FEATURES_KHR
Layout
```
 struct VkPhysicalDevicePerformanceQueryFeaturesKHR {
     VkStructureType sType();
     void * pNext();
     VkBool32 performanceCounterQueryPools();
     VkBool32 performanceCounterMultipleQueryPools();
 }
