Question Can you make 4 separate Minecraft processes use equal amounts of memory/power?

[donkeydude125]

I have 4 separate Minecraft windows running at the same time on the same PC so I can play local multiplayer with my friends. Everything works except for one problem, it seems like when one MC window is highlighted/selected the other 3 windows lag more, but not evenly. My guess is that the other 3 "unselected" processes are considered to be in the "background", so they don't get as much power.

Is there a way to fix this? Can I somehow allocate the same amount of resources to all 4 windows regardless if they are "selected" or not?

Here are my PC specs if needed: https://ca.pcpartpicker.com/user/donklyknob/saved/b24Jbv
I'm on Windows 10

You can look in this link you can make mc start with high priority,
-Xmx1024M -Xms1024M these two commands are to keep ram usage in check.
