Unity 2017 Game Optimization - Second Edition

By: Chris Dickinson

Overview of this book

Unity is an awesome game development engine. Through its massive feature-set and ease-of-use, Unity helps put some of the best processing and rendering technology in the hands of hobbyists and professionals alike. This book shows you how to make your games fly with the recent version of Unity 2017, and demonstrates that high performance does not need to be limited to games with the biggest teams and budgets. Since nothing turns gamers away from a game faster than a poor user-experience, the book starts by explaining how to use the Unity Profiler to detect problems. You will learn how to use stopwatches, timers and logging methods to diagnose the problem. You will then explore techniques to improve performance through better programming practices. Moving on, you will then learn about Unity’s built-in batching processes; when they can be used to improve performance, and their limitations. Next, you will import your art assets using minimal space, CPU and memory at runtime, and discover some underused features and approaches for managing asset data. You will also improve graphics, particle system and shader performance with a series of tips and tricks to make the most of GPU parallel processing. You will then delve into the fundamental layers of the Unity3D engine to discuss some issues that may be difficult to understand without a strong knowledge of its inner-workings. The book also introduces you to the critical performance problems for VR projects and how to tackle them. By the end of the book, you will have learned to improve the development workflow by properly organizing assets and ways to instantiate assets as quickly and waste-free as possible via object pooling.

The future of Unity, Mono, and IL2CPP

When the first edition of this book was written, IL2CPP was being teased in a variety of blog posts, and Unity was still running a very old version of Mono. Well, the good news is that IL2CPP has finally landed, but the bad news is Unity is still running a very old version of Mono. This is an unfortunate consequence of how various elements of the Mono Framework are licensed, meaning that Unity Technologies has only been able to update Mono on an infrequent basis.

After many years, Unity is still only able to make use of the .NET 3.5 library functionality, which is about a decade old at this point. This limits what kinds of .NET library classes we can use, restricts certain C# language features, and limits performance since many enhancements would have been made to the library during this time. However, to the great relief of many Unity developers, an experimental upgrade to a more recent version of Mono has been in beta for a while and is now available...
