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.

Rendering performance enhancements

We should now have all of the information we need to make sense of performance bottlenecks so that we can start to apply fixes. For the remainder of this chapter, we will cover a series of techniques to improve Rendering Pipeline performance for CPU-bound and GPU-bound applications.

Enabling/disabling GPU skinning

The first tip involves a setting that eases the burden on the CPU or GPU frontend at the expense of the other, that is, GPU Skinning. Skinning is the process where mesh vertices are transformed based on the current location of their animated bones. The animation system, working on the CPU, transforms the object's bones that are used to determine its current pose, but the next...
