Hi! This is a non-essential question. Just curious. When I run two instances of EUIV on my machine, which has a 7950X3D, one CPU goes 100%. When I run multiple instances, it shares CPU processing power between the instances on that same core. Why doesn't multiple instances of EUIV use different primary cores? Or is there a method to make each instance use a different primary CPU core.
 
I don't believe there is any testing done on the scenario of multiple instances on the same computer, so whatever happens when you do that is what happens!

You can certainly use Affinity to affect what cores the game uses, but how that would work with two eu4.exe instances I'm not sure.
 
This is probably something which you have to configure in your OS. I just tried to run 4 instances of eu4 on Linux and they used all four of my CPU cores.
