Hello so I'm completely new to multiboxing, the idea only crossed my mind a few days ago and now here I am. Of course, I'm having issues because why would anything as technical as this, just run smoothly first shot.

What I'm attempting to do:
Dual box WoW -(control 2 toons simultaneously)

What Program am I using to do this:
ISBoxer

What exactly is my issue?
My main box is experiencing stability issues. Frame rate is all over the place. However, the 2nd box is running mint! if I swap to the 2nd WoW process it runs fine whether its the active or inactive window. Now, I suspect this has to be a configuration issue with ISBoxer. I'm unsure what else it could be possibly be.

Some potentially useful details of things I've done/checked:
While running ISBoxer I opened task manager to view my resources. I'm only using 9-10% CPU, and 20% Memory. I've tried different window layouts aswell. One thing I havent done, is create two separate folders for the WoW directory to boot separate config files.
