I've rewritten large chunks of the city logic, which is now computed on your other CPU thread core. What does that mean? Well, that the stutters should be now gone, and that big city will update way faster than before
💨From my testing, a large, 9 levels city that used to update every 3 minutes now updates every 20 seconds! Of course, there is more work to be done on the FPS side with the 3D model optimizations, but apart from that, you can now scale your city to be HUGE. Please do it.

🚀 The rocket port is now launching an actual rocket every 60 seconds.
