Path placement causes a lot of lag, performance drop when laying roads

4 votes

When the path network of a district is already very big and convoluted, the game grinds to a halt when a piece of path is connected in the building tool.
The same is true for attaching new buildings to existing paths as you place them.
This lag, probably caused by re-evaluating path connectivity, makes the game fee very slow even though it is otherwise not slow at all.

I understand that a global and slow view on the whole path network might be necessary to turn "more red" areas into "more green" areas in the preview if there is a new shortcut formed. When placing a building or just extending a path, this global effect doesn't matter and the new path parts only get "longer". Having no "further" parts connected anew by the new connection could be a good shortcut to cut off the search already there. After that, only closing path loops would still have this perceptible lag.

Could have an option for "fast path previews" that didn't follow the "further" paths.
