Profiling and Memory in Unity and Unreal | Start Mentor Workshop
This video provides an in-depth guide to profiling in Unity and Unreal Engine, led by Start Mentor Sidney. The session covers the philosophy of performance, practical tool demonstrations, and strategies for maintaining optimization throughout the development lifecycle. Key Topics Covered Performance as a Feature: Why you should profile early, often, and directly on-device to avoid last-minute optimization hurdles. Unity Profiler Deep Dive: Understanding the Timeline and Hierarchy views to diagnose CPU usage and identify bottlenecks. Memory Management: Using the Unity Memory Profiler to track allocated memory, identify leaks, and manage resource pressures like render textures. Unreal Engine Insights: Navigating the “Epic way” of profiling, including how to handle Unreal's multi-threaded architecture and graphics settings for mobile VR. Automated Testing: An introduction to automated performance testing frameworks to streamline your optimization workflow. This session was recorded in May 2026 as part of the Meta Horizon Start program. 🎬 CHAPTERS 00:05 – Introduction and Speaker Background 00:43 – The Importance of Profiling: Performance as a Feature 01:12 – Pro-tip: Profile Early, Often, and on Device 05:09 – Unity Profiler: Timeline and Hierarchy Views 09:01 – Diagnosing CPU Issues and Editor Noise 10:08 – Unity Memory Profiler: Snapshots and Leaks 14:18 – Unreal Engine Optimization Philosophy 17:12 – Unreal Insights: Tracing and Thread Analysis 18:53 – Automated Performance Testing Frameworks 📚 ADDITIONAL RESOURCES ➡️ Developers Blog ➡️ Meta Quest Developer Hub 🔗 CONNECT WITH US Sign up to get the latest news from Meta Horizon. 💡 LEARN ABOUT THE META HORIZON START PROGRAM The Meta Horizon Start program provides intermediate and advanced developers with hands-on support and expert guidance to accelerate app development.
