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.

Disabling unused scripts and objects

Scenes can get pretty busy sometimes, especially when we're building large, open worlds. The more objects there are invoking code in an Update() callback, the worse it will scale and the slower the game becomes. However, much of what is being processed may be completely unnecessary if it is outside of the player's view or simply too far away to matter. This may not be a possibility in large city-building simulation games, where the entire simulation must be processed at all times, but it is often possible in first-person and racing games since the player is wandering around a large expansive area, where non-visible objects can be temporarily disabled without having any noticeable effect on gameplay.
