To have proper call stack information, the profiled application must be compiled with debugging symbols enabled. You can achieve that in the following way:
\begin{itemize}
\item On MSVC open the project properties and go to \emph{Linker\textrightarrow Debugging\textrightarrow Generate Debug Info}, where the \emph{Generate Debug Information} option should be selected.
\item On gcc or clang, link the executable with an additional option \texttt{-rdynamic} (or \texttt{-{}-export-dynamic}, if you are passing parameters directly to the linker).
\end{itemize}

\section{Practical considerations}
Tracy's time measurement precision is not infinite. It's only as good as the system-provided timers are.
