Unity Profiler Skill Skill

Unity Profiler Skill

Performance profiling and optimization using Unity Profiler tools.

Overview

This skill provides capabilities for analyzing and optimizing Unity game performance using the Profiler, Frame Debugger, and Memory Profiler.

Capabilities

CPU Profiling

Analyze frame timing
Identify bottlenecks
Profile custom code markers
Handle deep profiling

GPU Profiling

Analyze render passes
Profile shader performance
Identify overdraw
Debug draw calls

Memory Profiling

Track allocations
Identify memory leaks
Analyze texture memory
Profile managed heap

Automated Analysis

Create profiler scripts
Set up performance tests
Generate reports
Monitor regressions

Prerequisites

Unity 2021.3+
Profiler module (built-in)
Memory Profiler package (optional)

Usage Patterns

Custom Profiler Markers

using Unity.Profiling;

public class OptimizedSystem : MonoBehaviour
{
    static readonly ProfilerMarker s_UpdateMarker =
        new ProfilerMarker("MySystem.Update");

    void Update()
    {
        using (s_UpdateMarker.Auto())
        {
            // Code to profile
            ProcessEntities();
        }
    }
}

Performance Test

[Test, Performance]
public void TestSpawnPerformance()
{
    Measure.Method(() =>
    {
        for (int i = 0; i < 1000; i++)
        {
            SpawnEnemy();
        }
    })
    .WarmupCount(3)
    .MeasurementCount(10)
    .Run();
}

Best Practices

Profile on target hardware
Use profiler markers
Test with realistic data
Monitor frame budget
Track memory over time
