Why does this SUPER simple line of code take 35% or my processing power?

Question

For my Job I am trying to create a Heartbeat program that monitors the status of interactives. In order to do this safely, I don't want clients closing out of the program, so I want to hide the window.

This is the single line of code that causes 35% of my processing power to be used when I run it. There is nothing in the scene and no other scripts.:

 void OnApplicationFocus(bool hasFocus)
 {
    User32.ShowWindow(User32.GetActiveWindow(), 0);
 }

Once you build your application, this code should immediately hide it. Now if you open Task Manager, you can see that when the application is hidden, it takes a lot of processing power. Anyone know why?

hi, unity3d doesn't recognize of being hided by windows so you need to manually hide your gameObjects to not call the draw function of unity .

see this reference to your problem

But I have no objects in the scene. When the window is visible, the processing power consumed is about .5%, when it's hidden it turns into 35%.
