Framerate Drop in Utilities Mode because of Connections

[Ulleulle]

I have a 500 Max-Sec - Prison with ~80 CCTVs, so 10 CCTV-Monitors...
I build my 2 security office rooms on the left border of a small map. When i was zooming out to
reach farther away CCTVs i recognised a huge drop on my framerate starting after roughly ten connections.
Doing further i think 1-3 FPS was all i had. After leaving the Utilites-Mode i instantly had ... playable Framerate (20 i guess ).

(Just to make sure: At the end ~80 Connections, zoomed out on a small map. Game was at pause. Framerate horrible.
80 Connections going out, zoomed out only on the 2 rooms with alle the monitors, Framerate over 30.)

Anyone noticed similar? Are this Connections so hard to render?

i have a prison with over 300 door connections alone. it drops quite badly. it is not "as" bad if you pause the game while in utilities mode and also try to stay zoomed in a reasonable amount.
