Detailed Description

Provides high-resolution timing utilities based on Win32 performance counters.

This file provides three tightly related timing utilities:

1. Timer — a manual high-precision stopwatch (microsecond resolution) for ad hoc measurements.
2. ScopedTimer — an RAII wrapper that measures a scope’s execution time and stores results in a static collection.
3. Time — a global monotonic clock utility for frame timing and delta calculations.

Example usage

Manual Timer

Raven::Timer timer;
// ... work ...
float ms = timer.ElapsedMillis();

ScopedTimer

{
    Raven::ScopedTimer timer("LoadMesh", 10.0f);
    LoadMesh();
} // Automatically logs if exceeded 10 ms

Time

float current = Raven::Time::GetTime();
float delta = current - last;
last = current;
