Low FPS in editor 5.3 with RTX 3090 and 5950X 4.3Ghz

The problem is that I have it in most example scenes. Everything just feels too slow. And also the creator of this free file said he got 70 fps in Cinematic mode on a laptop. That would mean he was using the same settings as in the file and on Cinematic mode. If you have the time, could you maybe download the file and give it a try? If only I know if others are getting much better performance with these sample scenes then I know there is probably a problem with my setup.
