Detailed Description

Encapsulates a latency timer that measures the time from when mouse input is read on the gamethread until that frame is fully displayed by the GPU.

Constructor & Destructor Documentation

FInputLatencyTimer()

FInputLatencyTimer::FInputLatencyTimer ( float  InUpdateFrequency )

inline

Constructor

Parameters

InUpdateFrequency

How often the timer should be updated (in seconds).

Member Function Documentation

GameThreadTick()

void FInputLatencyTimer::GameThreadTick

(

)

Potentially starts the timer on the gamethread, based on the UpdateFrequency.

GetDeltaSeconds()

float FInputLatencyTimer::GetDeltaSeconds ( ) const

inline

Returns

The number of seconds of input latency.

Member Data Documentation

bInitialized

bool FInputLatencyTimer::bInitialized = false

Whether GInputLatencyTimer is initialized or not.

DeltaTime

uint32 FInputLatencyTimer::DeltaTime = 0

Last delta time that was measured (in FPlatformTime::Cycles).

GameThreadTrigger

bool FInputLatencyTimer::GameThreadTrigger = false

Whether a measurement has been triggered on the gamethread.

LastCaptureTime

double FInputLatencyTimer::LastCaptureTime = 0.0f

Last time we did a measurement (in seconds).

RenderThreadTrigger

bool FInputLatencyTimer::RenderThreadTrigger = false

Whether a measurement has been triggered on the renderthread.

StartTime

uint32 FInputLatencyTimer::StartTime = 0

Start time (in FPlatformTime::Cycles).

UpdateFrequency

float FInputLatencyTimer::UpdateFrequency

How often we should do a measurement (in seconds).
