# VkLatencySleepModeInfoNV(3) Manual Page

## Name

VkLatencySleepModeInfoNV - Structure to set low latency mode

Loading… please wait.

## C Specification

The `VkLatencySleepModeInfoNV` structure is defined as:

    // Provided by VK_NV_low_latency2
    typedef struct VkLatencySleepModeInfoNV {
        VkStructureType    sType;
        const void*        pNext;
        VkBool32           lowLatencyMode;
        VkBool32           lowLatencyBoost;
        uint32_t           minimumIntervalUs;
    } VkLatencySleepModeInfoNV;

## Members

- `sType` is a VkStructureType value identifying this structure.

- `pNext` is `NULL` or a pointer to a structure extending this structure.

- `lowLatencyMode` is the toggle to enable or disable low latency mode.

- `lowLatencyBoost` allows an application to hint to the GPU to increase performance to provide additional latency savings at a cost of increased power consumption.

- `minimumIntervalUs` is the microseconds between vkQueuePresentKHR calls for a given swapchain that vkLatencySleepNV will enforce.

## Description

If `lowLatencyMode` is `VK_FALSE`, `lowLatencyBoost` will still hint to the GPU to increase its power state and `vkLatencySleepNV` will still enforce `minimumIntervalUs` between `vkQueuePresentKHR` calls.

Valid Usage (Implicit)

- VUID-VkLatencySleepModeInfoNV-sType-sType
  `sType` must be `VK_STRUCTURE_TYPE_LATENCY_SLEEP_MODE_INFO_NV`
