# VkLatencyTimingsFrameReportNV(3) Manual Page

## Name

VkLatencyTimingsFrameReportNV - Structure containing latency data

## C Specification

The VkLatencyTimingsFrameReportNV structure describes latency data returned by vkGetLatencyTimingsNV

    // Provided by VK_NV_low_latency2
    typedef struct VkLatencyTimingsFrameReportNV {
        VkStructureType    sType;
        void*              pNext;
        uint64_t           presentID;
        uint64_t           inputSampleTimeUs;
        uint64_t           simStartTimeUs;
        uint64_t           simEndTimeUs;
        uint64_t           renderSubmitStartTimeUs;
        uint64_t           renderSubmitEndTimeUs;
        uint64_t           presentStartTimeUs;
        uint64_t           presentEndTimeUs;
        uint64_t           driverStartTimeUs;
        uint64_t           driverEndTimeUs;
        uint64_t           osRenderQueueStartTimeUs;
        uint64_t           osRenderQueueEndTimeUs;
        uint64_t           gpuRenderStartTimeUs;
        uint64_t           gpuRenderEndTimeUs;
    } VkLatencyTimingsFrameReportNV;

## Members

The members of the VkLatencyTimingsFrameReportNV structure describe the following:

## Description

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

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

- `presentID` is the application provided value that is used to associate the timestamp with a `vkQueuePresentKHR` command using VkPresentIdKHR::`pPresentIds` or VkPresentId2KHR::`pPresentIds` for a given present.

- `simStartTimeUs` is the timestamp written when `vkSetLatencyMarkerNV` is called with the VkLatencyMarkerNV enum VK_LATENCY_MARKER_SIMULATION_START_NV.

- `simEndTimeUs` is the timestamp written when `vkSetLatencyMarkerNV` is called with the VkLatencyMarkerNV enum VK_LATENCY_MARKER_SIMULATION_END_NV

- `renderStartTimeUs` is the timestamp written when `vkSetLatencyMarkerNV` is called with the VkLatencyMarkerNV enum VK_LATENCY_MARKER_RENDERSUBMIT_START_NV.

- `renderEndTimeUs` is the timestamp written when `vkSetLatencyMarkerNV` is called with the VkLatencyMarkerNV enum VK_LATENCY_MARKER_RENDERSUBMIT_END_NV.

- `presentStartTimeUs` is the timestamp written when `vkSetLatencyMarkerNV` is called with the VkLatencyMarkerNV enum VK_LATENCY_MARKER_PRESENT_START_NV.

- `presentEndTimeUs` is the timestamp written when `vkSetLatencyMarkerNV` is called with the VkLatencyMarkerNV enum VK_LATENCY_MARKER_PRESENT_END_NV.

- `driverStartTimeUs` is the timestamp written when the first `vkQueueSubmit` for the frame is called.

- `driverEndTimeUs` is the timestamp written when the final `vkQueueSubmit` hands off from the Vulkan Driver.

- `osRenderQueueStartTimeUs` is the timestamp written when the final `vkQueueSubmit` hands off from the Vulkan Driver.

- `osRenderQueueEndTimeUs` is the timestamp written when the first submission reaches the GPU.

- `gpuRenderStartTimeUs` is the timestamp written when the first submission reaches the GPU.

- `gpuRenderEndTimeUs` is the timestamp written when the final submission finishes on the GPU for the frame.

Valid Usage (Implicit)

- VUID-VkLatencyTimingsFrameReportNV-sType-sType
  `sType` must be VK_STRUCTURE_TYPE_LATENCY_TIMINGS_FRAME_REPORT_NV
