            #   Tracy Profiler initialization failure: CPU doesn't support invariant TSC.
            #   Define TRACY_NO_INVARIANT_CHECK=1 to ignore this error, *if you know what you are doing*.
            #   Alternatively you may rebuild the application with the TRACY_TIMER_FALLBACK define to use lower resolution timer.

            # about having a lower precision timer.
