Hardware Settings Support

Hi, is there a support site where you can read how to properly set up your graphics card and PC system.

I have a Nvidia 3080 GTX and an Intel Core i7 10700KF this hardware is not being utilized the GPU is at 30% and the CPU also at just 30% utilization.
But I have extremely bad performance in UE5 editor just one 9-19 FPS.
In the packed version just 25-30 FPS.

I have the feeling that the graphics card is not supported.
How can I adjust my system?

Thanks in advance
