# VkPerformanceCounterDescriptionFlagBitsKHR(3) Manual Page

## Name

VkPerformanceCounterDescriptionFlagBitsKHR - Bitmask specifying usage behavior for a counter

## C Specification

Bits which can be set in VkPerformanceCounterDescriptionKHR::`flags` to specify usage behavior for a command pool are:

    typedef enum VkPerformanceCounterDescriptionFlagBitsKHR {
        VK_PERFORMANCE_COUNTER_DESCRIPTION_PERFORMANCE_IMPACTING_KHR = 0x00000001,
        VK_PERFORMANCE_COUNTER_DESCRIPTION_CONCURRENTLY_IMPACTED_KHR = 0x00000002,
        VK_PERFORMANCE_COUNTER_DESCRIPTION_FLAG_BITS_MAX_ENUM_KHR = 0x7FFFFFFF
    } VkPerformanceCounterDescriptionFlagBitsKHR;

## Description

- `VK_PERFORMANCE_COUNTER_DESCRIPTION_PERFORMANCE_IMPACTING_KHR` specifies that recording the counter may have a noticable performance impact

- `VK_PERFORMANCE_COUNTER_DESCRIPTION_CONCURRENTLY_IMPACTED_KHR` specifies that concurrently recording the counter while other submitted command buffers are running may impact the accuracy of the recording
