How to make the editor running at 60fps even when it's not in focus?

So if you select some other window that is not part of Unity, Unity Editor will drop it's framerate to 20-30 fps. Maybe even lower. Is there a way to change this so its always 60.

Unreal Engine has an option for this, but I cannot find one in Unity.

Thanks

 

Not sure how Unreal is doing it, but the operating system is what schedules a process on the CPU. You can adjust priority of a process in the task manager on Windows. Though the Windows scheduler also gives an additional priority boost automatically to any application which is currently in focus.
