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.

Faster Physics

Each of the performance-enhancing suggestions we've explored so far has been primarily centered on reducing resource costs and avoiding frame rate issues. However, at its most fundamental level, seeking peak performance means improving the user experience. This is because every frame rate hiccup, every crash, and every system requirement that is too costly for a given market ultimately detracts from the quality of the product. Physics engines are a unique category of subsystems whose behavior and consistency contributes a significant factor toward product quality. Spending the time to improve their behavior is often worth the cost.

If important collision events get missed, the game freezes while it calculates a complex physics event, or the player falls through the floor, these scenarios have an obvious and significant negative impact on the quality of gameplay...
