Bad FPS with nice config

Hello, so this is my problem, I don’t know if it’s normal, if it comes from the game or from my pc but, in my game where I currently have 23 small worker

, and where I don't have too much construction , I only shoot around 50-60 fps, and I find it really strange, because with a config like that I told myself that it would run perfectly, but no .. part of my config: RTX 2080TI 32GB RAM DDR4 I9-9900K

I’m on windows 10, and the game is in 64 bits. i have put the graphics option on Ultra.

So if you have an idea, thank you in advance.

Town:

Its pretymuch the game. in an old version you could get stupid high FPS but somewhere along the way that dropped way down.

there are no solutions?
