Rendering graphics in Unity is a complex task. This guide provides a better understanding of the underlying concepts related to rendering, and best practices for reducing the rendering workload on the GPU.

A profiling tool gives detailed information about how a game is performing. The Profiler window is a powerful profiling tool that is built into Unity. This tutorial describes what the Profiler window is used for and how to use it to diagnose performance problems in a game or other application.

In this tutorial, you will learn how to use the Physics Debugger.

It’s common for a project to grow beyond a designer’s initial vision, or for that initial vision to be more resource-intensive than originally thought. Much of a project’s optimization will be unique to its design, but even the simplest project can benefit from optimization. In this tutorial, you will learn about different approaches to take for optimizing projects.

Unity’s optimization tools allow you to diagnose common performance problems and refine a project’s design, code, and related assets to maximize efficiency. An optimized project will run smoother and more responsively on your target platforms and devices. This tutorial will help you better understand optimization tools and techniques available in Unity and provides suggested uses for each tool. To learn how to use each tool, please refer to the following tutorials: Working with the Profiler Window, Working with the Stats Window, Working with the Frame Debugger, and Optimization Approaches for Project Assets.

The Frame Debugger is a handy tool that allows you to freeze playback for a running game on a particular frame to view the individual draw calls used to render that frame. The debugger also lets you go through frames one-by-one so you can see in greater detail how the scene is constructed. In this tutorial, you will learn about the Frame Debugger and how to use it for analysis.

In this tutorial, we’ll explore Assembly Definitions. An Assembly Definition groups code into an Assembly. An Assembly might be based on origin, purpose, and/or whatever criteria best suits your project. An Assembly Definition can also depend on the platform. By default, all code in a Unity project belongs to a single Assembly, called Assembly-CSharp.

In this tutorial, you’ll learn how to use the StreamingAssets folder to allow users to load their own images, songs, and even game levels into a project.
