Framerate drop when packaged game out of focus

Hi, I need to run two packaged projects such that both game windows display on screen at the same time. The problem is that when one window is in focus, the other severely drops framerate. How can I allow both windows to run at full speed, even when not in focus? As far as I am aware, the editor preferences setting only affects the editor in this case.

When the application has lost focus, some events will be called like this condition.Maybe you can reading source code some relatived like word ‘Use less cpu…’ to find out some ideals,

I don’t know the answer. This problem has always existed

There’s code in the uppermost engine/world step loop that sleeps a little bit each frame if the game doesn’t have focus.
Last I checked, you can turn this off with a console variable, but I forget what it’s called.
