DisableTimestampReset

Gets or sets whether the timestamp should be reset using the wall clock after TimestampResetInterval milliseconds elapse between frames.

Declaration

public bool DisableTimestampReset { get; set; }

Property Value

Type	Description
System.Boolean

ForceTimestampReset

Gets or sets whether the timestamp should be reset before the next frame is processed.
