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.

Section 3: Advance Optimizations


This chapter introduced you to many methods that will improve your scripting practices in the Unity Engine and to improve performance if (and only if) you have already proven some scripts are the cause of a performance problem. Some of these techniques demand some forethought and profiling investigation before being implemented since they often come with introducing additional risks or obfuscating our code base. Workflow is often just as important as performance and design, so before you make any performance changes to the code, you should consider whether or not you're sacrificing too much on the altar of performance optimization.

We will investigate more advanced scripting improvement techniques later, in Chapter 8, Masterful Memory Management, but let's take a break from staring at code and explore some ways to improve graphics performance using a pair of...
