Resolved Solution for severe lag Unity editor when using multiple sceens

I'm working in a URP project on version 2022.2.20f1. But I've been experiencing lag when using multiple screens, which started all the way back to a 2019 version of Unity. Through the years I did some searched on google, trying to find a solution to this problem. I found out there were a lot of people struggling with the same thing. There were some mentions of external USB devices causing lag. But that wasn't the case for me. Today I found a solution.

The solution was very simple.. Just whish I would've found it sooner. Play around with the render pipeline settings. For me completely disabling the Anti Aliasing, and trying different values in the render scale did the trick. The reason why I didn't check this out before, is because my system should be powerful enough to handle it. But maybe it's somekind of a sync issue. When I eventually build the project I will once again enable these options in the render pipeline.

Hope this helps those experiencing the same problem.
