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.

Have you found a solution to this? I’m facing the same issue in my packaged build when running in VR mode and spectator camera.

Sadly, no. We resolved it by literally using two PCs and converting the project to pass network inputs to each other.

I know it’s an old topic but I just had the same issue when testing Lyra project, and found answer in another post.
Turn out it was an issue with fps set to unlimited so the focused Windows was taking almost all the performance letting very little for the other out of focus instance:
