Unity Game Optimization - Third Edition

By: Dr. Davide Aversa, Chris Dickinson

Overview of this book

Unity engine comes with a great set of features to help you build high-performance games. This Unity book is your guide to optimizing various aspects of your game development, from game characters and scripts, right through to animations. You’ll explore techniques for writing better game scripts and learn how to optimize a game using Unity technologies such as ECS and the Burst compiler. The book will also help you manage third-party tooling used with the Unity ecosystem. You’ll also focus on the problems in the performance of large games and virtual reality (VR) projects in Unity, gaining insights into detecting performance issues and performing root cause analysis. As you progress, you’ll discover best practices for your Unity C# script code and get to grips with usage patterns. Later, you’ll be able to optimize audio resources and texture files, along with effectively storing and using resource files. You’ll then delve into the Rendering Pipeline and learn how to identify performance problems in the pipeline. In addition to this, you’ll learn how to optimize the memory and processing unit of Unity. Finally, you’ll cover tips and tricks used by Unity professionals to improve the project workflow. By the end of this book, you’ll have developed the skills you need to build interactive games using Unity and its components.

Masterful Memory Management

Memory efficiency is an important element of performance optimization. It's possible for games of limited scope, such as hobby projects and prototypes, to get away with ignoring memory management. These games will tend to waste a lot of resources and potentially leak memory, but this won't be a problem if we limit its exposure to friends and coworkers. However, anything we want to release professionally needs to take this subject seriously. Unnecessary memory allocations lead to poor user experience due to excessive garbage collection (costing precious CPU time) and memory leaks, which will lead to crashes. None of these situations are acceptable in modern game releases.

Using memory efficiently with Unity requires a solid understanding of the underlying Unity engine, the Mono platform, and the C# language. Also, if we're making use...
