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.

The Unity Job System

The big block in the DOTS that can provide us with a huge performance-enhancing feature is the C# Job System. Like all the other DOTS components, the feature is still in active development, but has been made public since Unity 2019.1, so it would be wise to start becoming familiar with it sooner rather than later, as it will introduce considerable changes to how Unity developers will be writing high-performance code:

As we will see, the difference in the quality of a game that uses this system versus one that doesn't might become very noticeable, which may cause some fragmentation within the Unity development community. It is in our best interests to understand and exploit the benefits of the new Job System so that our application will have the greatest potential for success.

The idea of the C# Job System is to be able to create simple tasks that run...
