The new city manager of Cities: Skylines 2 from the Colossal Order studio is so bad with optimization that the game even on the most powerful hardware shows frankly weak values.
Users post a video online that shows that even in an empty location the frame counter drops to 20. In this case, extremely powerful hardware is used in the form of an RTX 4090 video card (albeit, with high settings and 4K resolution). If you build a large city, this value drops by half, making it impossible to play at all. And this is sad, because the game itself is not bad, but due to terrible optimization it cannot reach its full potential.
The release of Cities: Skylines 2 on PC has already taken place, and the project will appear on consoles in the spring of next year.
