Update()'s refresh interval and how to change.

I want to know Update()'s refresh interval and how to change.
usually, if we get time, that is ms unit. frame is usually 60 per second.
In my opinion, Update() function maybe refresh 60frame but I have no confidence.
I appreciate if you teach me those or how to know(something like reference).
I’m so noob T.T

Update runs every frame. You can’t change this, and there is no set interval. Normal behavior is to run as fast as possible, but you can use vsync or Application.targetFrameRate to limit it.

Besides what Eric5h5 said, if you are merely interested in the time interval between two frames (since the framerate at which Update() is called is generally not constant):

Time.deltaTime contains the time in ms it took to render the previous frame. You can scale your timing critical parameters in Update() with this value, to make them framerate-independent.

There is a “stats” button that displays technical information. It is on the game window next to “maximize on play”

Is that what you meant?

You may call Application.targetFrameRate to set the well… desired frameRate. Alternatively you could implement your own update-like method. There’s many different implementations for this (on this very forum), a simple one could look like this:

var updateInterval:float = 0.1f;

function Start()
{
    InvokeRepeating("UpdateInterval",updateInterval,updateInterval);
}

function UpdateInterval()
{
    //use this as the secondary update.
}
