How to run gzDoom in a window, without focusing on the tab?

[CD-Roman]

I want to run 2 simultaneous gzdoom to play multiplayer in window mode side by side, however, only one exe is refreshing the screen, the other one works,
but is frozen. Is there any workaround?

Set vid_activeinbackground CVAR to true.

WORKS great. That command is somewhere in the game options?

No, menu is already cluttered with way too many kinda useful options.

I understand. I appreciate super fast reply!
One more question related to this mode - is it possible to control both windows using two separate controllers?
As far as I understand, Doom does not see the difference beetween Device 1 Xbox Controller and Device 2 Xbox Controller, I have also tried a combination of Xbox 360 and Xbox One controllers, using two separate USB receivers, but the input is accepted from both windows at the same time.

I have even went as far as configuring one profile as controller binds exclusively, and the second window as keyboard only, and using an 3rd party app that is using xinput/directinput to translate it to keyboard buttons, so when I press A on my Xbox controller, it will press space on the keyboard, which would translate it to the Doom as jump command. It does work, but if I press the A button, both windows accepts the input and is following the bind command.

I have even tried to run two seperate exe from two folders. Still no luck.
I'm trying to ge gzDoom to work in side-by-side multiplayer mode.
Thanks in advance!

Did you ever get it to work?
I want to take this idea and run with it, i.e. as many instances of doom as possible with a ton of controllers.
