Enable the FrameTimingManager

Tip: FrameTimingManager is always active for Development Player builds.

To enable the FrameTimingManage for Release builds and in the Unity Editor:

1. Go to Edit > Project Settings > Player.
2. In Other Settings, navigate to the Rendering heading.
3. Enable the Frame Timing Stats property.

If you use the OpenGL platform, you also need to enable the OpenGL: ProfilerA window that helps you to optimize your game. It shows how much time is spent in the various areas of your game. For example, it can report the percentage of time spent rendering, animating, or in your game logic. More info
See in Glossary GPU Recorders property to measure GPU usage. To do this:

1. Go to Edit > Project > Settings > Player.
2. In Other Settings, navigate to the Rendering heading.
3. Enable the OpenGL: Profiler GPU property.

Note: In Unity versions 2021.2 and earlier, the OpenGL Profiler GPU Recorder disables the Frame Timing Stats property, so you can’t use them together.

To access data that the FrameTimingManager records, use one of the following methods:

• Retrieve timestamp data from the FrameTimingManager C# API.
• View frame time data in a Custom Profiler module.
• Record data through specific profiler counters.
