How to show FPS in Unity3D C#

Showing FPS can be helpful when you’re on a handheld device and gauging performance.

Sometimes you may need to throttle quality for device depending on the performance.

This code is how you display FPS in C# for a mono behaviour script.

1. void Update () {
2. deltaTime += (Time.deltaTime - deltaTime) * 0.1f;
3. float fps = 1.0f / deltaTime;
4. Debug.Log(Mathf.Ceil(fps).ToString() + “ FPS”);
5. }
