The UI and UI Details areas

These areas provide insight into applications making use of Unity's built-in user interface system. If we're using a custom-built or third-party user interface system (such as the popular Asset Store plugin Next-Gen UI (NGUI)), then these areas will probably provide little benefit.

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