Performance Drop in one Room only

For most of the Time the Performance is absolutely fine for me. Stable 60fps on High with RTX on.

There is just one Room where my FPS drop massively, shortly down to 20, then back up to 45. As soon as i leave this Room, i get stable 60 again.


My guess would be that it is because of all the Light Sources there.
