The UI and UI Details Areas

These Areas are new in Unity 2017 and provide insight into applications making use of Unity's built-in User Interface System. If we’re using a custom-built or 3rd-party User Interface System (such as NGUI), then these Areas will probably provide little benefit.

Poorly optimized user interface can often affect one or both of the CPU and GPU, so we will investigate some code optimization strategies for UI in Chapter 2, Scripting Strategies, and graphics-related approaches in Chapter 6, Dynamic Graphics.
