Yes, PC.Since it's SF6 I assume you're using PCs?
Have you had any issues with vsync or tearing between the two displays? I can't seem to get my setup to not have tearing on one display. I've tried setting them both to 60hz, different cables, forcing vsync on or off, toggling freesync, no good. I can only assume it's either because they're two different monitors, or my video card isn't up for it for whatever reason.
What do you mean they're two different monitors? Do you mean actual different models with different specs?
I'm running at 165hz over displayport, vsync off, screens mirrored from a 3080, no tearing.
