Solved! SLI gtx 1070 software

Nov 4, 2018
So, I have 2 gtx 1070s in Sli, I heard there is a program that would allow me to use them both to where i can play games on both of them at the same time. Lol that's confusing. I heard there is a program where I can play fortnite with my roommate off of one pc and two monitors both of us on 2 separate accounts. Do you know what that software or program is?
