🔥 UltraTimerWindows

---

🚀 Overview

UltraTimerWindows is a zero-allocation, native high-resolution timer for Unity, built on top of Windows QueryPerformanceCounter. Suitable for micro-benchmarks and hot-path measurements. Provides sub-millisecond and microsecond-level timing precision.

The overhead of the timer itself is negligible compared to typical Unity workloads.

✨ Features

• ⚡ High-resolution native timing in pure C (WinAPI QueryPerformanceCounter)
• 🧹 Zero GC allocations during measurement
• 🔒 Deterministic and low-overhead
• 🔥 Suitable for micro-benchmarks and hot-path measurements
• ⚙️ IL2CPP & Mono compatible
• 🧩 Scoped measurement via using
• 🎞️ Profile sampling for each scope
• 🔬 Independent from Unity Profiler

💻 Usage

UltraTimerWindows provides very elegant and simple API:

---

💡 Basic example of usage

using UnityEngine;
// Namespace
using HardCodeDev.UltraTimerWindows.Runtime;

public class TestTimer : MonoBehaviour
{
    // Timer
    private UltraTimerWindows _timer;

    private void Start() => _timer = new();
    
    private void Update()
    {
        using (_timer.Measure()) 
        {
          // Here you can call any methods you want to measure
          HeavyMethod();
        }

        // See results in the console
        Debug.Log($"Last elapsed: {_timer.State.lastElapsedMs} ms, " +
            $"total elapsed: {_timer.State.totalElapsedMs} ms, " +
            $"average: {_timer.State.averageMs} ms, " +
            $"called: {_timer.State.countOfCalling} times");
    }

    private void HeavyMethod()
    {
        for (int i = 0; i < 100000; i++)
        {
            float x = Mathf.Sqrt(i);
        }
    }
    
    // Don't forget about disposing!
    private void OnDestroy() => _timer?.Dispose();  
}

---

🎞️ Profile Sampling

using (_timer.Measure("Name of Sample")) 
{
  // Here you can call any methods you want to measure
  HeavyMethod();
}

And then after running with enabled Profile you'll see:

---

🫡 Reset Timer

using (_timer.Measure()) 
{
  // Here you can call any methods you want to measure
  HeavyMethod();
}

if (_timer.State.countOfCalling == 1000) _timer.Reset();

Result:

---

That's it! Enjoy measuring your heavy stuff 😎
