These events will be reported as '\texttt{[x] Vsync}' frame sets, where \texttt{x} is the identifier of a specific monitor. Note that hardware vertical synchronization might not correspond to the one seen by your application due to desktop composition, command queue buffering, and so on. Also, in some instances, when there is nothing to update on the screen, the graphic driver may choose to stop issuing screen refresh. As a result, there may be periods where no vertical synchronization events are reported. Use the \texttt{TRACY\_NO\_VSYNC\_CAPTURE} macro to disable capture of Vsync events. |
