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 Benefits of Batching

In 3D graphics and games, batching is a very general term used to describe the process of grouping a large number of wayward pieces of data together and processing them as a single, large block of data. This situation is ideal for CPUs, and particularly GPUs, which can handle the simultaneous processing of multiple tasks with their multiple cores. Having a single core switching back and forth between different locations in memory takes time, so the less this needs to be done, the better.

In some cases, the act of batching refers to large sets of meshes, vertices, edges, UV coordinates, and other different data types that are used to represent a 3D object; however, the term could just as easily refer to the act of batching audio files, sprites, texture files, and other large datasets.

So, just to clear up any confusion, when the topic of batching is mentioned...
