Swappig between screens causes a ton of lag/stuttering

Good afternoon all,

I have a 3 toon team and run fixed (no swapping) setup on 1 monitor. Whenever I mouse to a different screen to interact with another character, I get a ton of lag/stuttering that makes the game virtually unplayable. The more I swap, the worse it gets, but if I stay on one screen, and don't interact with the others, it runs just fine. I should note that as a benchmark, I launched 3 accounts manually through the Blizzard launcher (outside of IS Boxer) and have no input lag or stuttering when switching between them. I've been troubleshooting solutions for a few days now, and it does not seem to be a hardware issue. Each account is set to full screen mode, with the lowest possible settings, and framerates on the default 30-60 setting.

Intel i7-9700k
RTX2080
32 Gigs Ram

Any ideas or other diagnostics I could run would be greatly appreciated. I suppose I could just play through multiple launchers, but it's just so sloppy, I cant bring myself to do it.

Thanks in advance!

This does seem a bit odd.

How about we start with a compatibility diagnostic so we can see what the games are loading.

Perfect, thank you.

Attached the diagnostic for your review.

Had a look. There is nothing outstanding to me in this.

Are you using a Round Robin CPU strategy ? A select all cores(CPUs) for all Games is the preferred strategy.
