I have four separate Minecraft games running at the same time on one computer. This lets me play with friends locally. Everything works fine except for one problem: when one game is selected, the other three start lagging more, but not all at once. I think the unselected programs are treated like background tasks and get less power. Is there a fix? Can I give each window exactly the same amount of resources whether it's active or not here? Here are my PC specs if needed: https://ca.pcpartpicker.com/user/donklyk...ved/b24Jbv I'm running Windows 10

You can look at this link or you could make Minecraft start with high priority, like -Xmx1024M and -Xms1024M. These two commands help keep the RAM usage in check. https://superuser.com/questions/371...-p...-minecraft
