Summary

In this tutorial, you’ll learn how to use the Profiler to analyze a scene and identify where optimization bottlenecks are occurring.

By the end of this tutorial, you will be able to:
Deduce the script method that uses the most CPU time (vs. a script method that does not) by using the CPU profiler in the Profiler window
Differentiate a loop that efficiently goes through a collection once in an Update() call from many loops that go through the same collection in an Update() call
Recognize possible issues that might cause performance problems (e.g., too many RigidBody components, too many Colliders, too many shadows, etc.), given a scenario
Investigate performance issues caused by poly count, texture sizes, or too many objects on the screen by using Unity's Stats window
Identify unnecessary nested if statements
