Unity Performance Profiling

Optimization without profiling is guesswork.

Use data.

Unity Profiler Overview

Unity Profiler tracks:

• CPU usage
• GPU load
• memory allocation
• rendering stats

These metrics reveal bottlenecks.

---

Common Performance Issues

Typical problems include:

• excessive draw calls
• frequent allocations
• heavy physics calculations
• inefficient scripts

Profiling identifies them quickly.

---

Profiling Workflow

1. Run the game
2. Record profiler data
3. Identify spikes
4. Optimize targeted systems

Repeat until stable.

Final Thoughts

Performance optimization requires discipline.

Measure first. Optimize second.
