Update

When I made this post, I wasn't using ISboxer. I was just opening 3 accounts and Alt+Tabn full screen on 4k max every setting possible. That worked fine with 2 accounts, but 3 made Tabn clunky. I DLed ISboxer and left all settings default going through the wizard. Now this might be a no brainer to most of you, but my game runs much smoother with ISboxer. Aside from the obvious game play comforts of ISboxer, I was able to turn my settings back to max, game runs flawlessly, and my load times are back to normal.
