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. }

Change Frame Rate in Unity3D

The FPS framerate in Unity3D is easier than ever with Unity3D 3.5+.

Below is the JS and the C# code counterpart:

    function Awake () {
        // Make the game run as fast as possible in the web player
        Application.targetFrameRate = 300;
    }

public class example : MonoBehaviour {
    void Awake() {
        Application.targetFrameRate = 300;
    }
}
