Hi there Diebre,
I know performance issues like this are never fun. I hope to help out here and get things working a bit better.
The first thing I see is that Razer software is on the computer. We have seen this causing performance issues on high end computers. We have a post about it linked above.
Out side of this I see a couple overlays on the systems. I would ask that everything extra be turned off to see if there is still a problem. Things like OBS and Corsair can cause problems. Turning them off for now is a good enough test.
Let us know if this information helps my friend!
