VkLatencyTimingsFrameReportNV

The VkLatencyTimingsFrameReportNV structure describes latency data returned by vkGetLatencyTimingsNV

typedef struct VkLatencyTimingsFrameReportNV {
    VkStructureType sType;
    const void* pNext;
    uint64_t presentID;
    uint64_t inputSampleTimeUs;
    uint64_t simStartTimeUs;
    uint64_t simEndTimeUs;

} VkLatencyTimingsFrameReportNV;

The members of the VkLatencyTimingsFrameReportNV structure describe the following:

• presentID is the application provided value that is used to associate the timestamp with a vkQueuePresentKHR command using VkPresentIdKHR::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.
