Variables

  Type Name Description
Public variable bool bBinThisFrame Should this frame be considered for histogram generation (controlled by t.FPSChart.MaxFrameDeltaSecsBeforeDiscarding)
Public variable bool bGameThreadBound Was this frame bound in one of the major functional units (only set if bBinThisFrame is true and the frame was longer than FEnginePerformanceTargets::GetTargetFrameTimeThresholdMS)
Public variable bool bGPUBound  
Public variable bool bRenderThreadBound  
Public variable bool bRHIThreadBound  
Public variable double DeltaSeconds Estimate of how long the last frame was (this is either TrueDeltaSeconds or TrueDeltaSeconds - IdleSeconds, depending on the cvar t.FPSChart.ExcludeIdleTime)
Public variable double DemoDriverTickFlushTimeSeconds Duration of the replay networking portion of the frame.
Public variable double DynamicResolutionScreenPercentage Dynamic resolution screen percentage. 0.0 if dynamic resolution is disabled.
Public variable uint32 FlushAsyncLoadingCount Total number of times FlushAsyncLoading() was called this frame.
Public variable double FlushAsyncLoadingTime Total time spent flushing async loading on the game thread this frame.
Public variable double GameDriverTickFlushTimeSeconds Duration of the primary networking portion of the frame (that is, communication between server and clients).
Public variable double GameThreadTimeSeconds Duration of each of the major functional units (GPU time is frequently inferred rather than actual)
Public variable double GPUTimeSeconds  
Public variable EFrameHitchType HitchStatus Did we hitch?
Public variable double IdleOvershootSeconds How long did we burn idling beyond what we requested this frame (FApp::GetIdleTimeOvershoot). WaitTime we requested for the frame = IdleSeconds - IdleOvershootSeconds.
Public variable double IdleSeconds How long did we burn idling until this frame (FApp::GetIdleTime) (e.g., when running faster than a frame rate target on a dedicated server)
Public variable double RenderThreadTimeSeconds  
Public variable double RHIThreadTimeSeconds  
Public variable uint32 SyncLoadCount The number of sync loads performed in this frame.
Public variable double TrueDeltaSeconds Time elapsed since the last time the performance tracking system ran.

Constructors

Public function   If a hitch, how was it bound.
