I was wondering if the lag you're experiencing still happens when DisplayFusion isn't running?

Thanks!

Even minimizing / closing / maximizing a window is laggy. When I open the Start Menu on an extended monitor, that is also very laggy.
Currently, I have one external 4k monitor connected via DisplayPort, and two more 4k monitors connected via a StarTech 4k USB-C HUB.

Any thoughts or suggestions on what I can do to improve performance?
