The members of the VkLatencyTimingsFrameReportNV structure describe the following:
Description
-
sTypeis a VkStructureType value identifying this structure. -
pNextisNULLor a pointer to a structure extending this structure. -
presentIDis the application-defined identifier of the application-rendered frame described by this structure. It is the same value that the application passes to vkSetLatencyMarkerNV via VkSetLatencyMarkerInfoNV::presentID. It is not related to presentIds passed via VkPresentIdKHR::pPresentIdsor VkPresentId2KHR::pPresentIds. -
simStartTimeUsis the timestamp written whenvkSetLatencyMarkerNVis called with the VkLatencyMarkerNV enum VK_LATENCY_MARKER_SIMULATION_START_NV. -
simEndTimeUsis the timestamp written whenvkSetLatencyMarkerNVis called with the VkLatencyMarkerNV enum VK_LATENCY_MARKER_SIMULATION_END_NV. -
renderStartTimeUsis the timestamp written whenvkSetLatencyMarkerNVis called with the VkLatencyMarkerNV enum VK_LATENCY_MARKER_RENDERSUBMIT_START_NV. -
renderEndTimeUsis the timestamp written whenvkSetLatencyMarkerNVis called with the VkLatencyMarkerNV enum VK_LATENCY_MARKER_RENDERSUBMIT_END_NV. -
presentStartTimeUsis the timestamp written whenvkSetLatencyMarkerNVis called with the VkLatencyMarkerNV enum VK_LATENCY_MARKER_PRESENT_START_NV. -
presentEndTimeUsis the timestamp written whenvkSetLatencyMarkerNVis called with the VkLatencyMarkerNV enum VK_LATENCY_MARKER_PRESENT_END_NV. -
driverStartTimeUsis the timestamp written when the firstvkQueueSubmitfor the frame is called. -
driverEndTimeUsis the timestamp written when the finalvkQueueSubmithands off from the Vulkan Driver. -
osRenderQueueStartTimeUsis the timestamp written when the finalvkQueueSubmithands off from the Vulkan Driver. -
osRenderQueueEndTimeUsis the timestamp written when the first submission reaches the GPU. -
gpuRenderStartTimeUsis the timestamp written when the first submission reaches the GPU. -
gpuRenderEndTimeUsis the timestamp written when the final submission finishes on the GPU for the frame.
