Interesting CPU problem when I'm on my test terrain with two feilds, two rivers, one 1x1 water object and the City\strats\HQ. I ran the create all for roads and trains.
Here is a screen shot of the City\strat\HQ complex I'm thinking of putting in my new terrain. While I'm over it in the TE like this my mouse is having problems in the terrain editor, in Firefox clicking on links or buttons and clipping and saving screen shots, anything I use the mouse for. It effects pages refreshing in Firefox and the task manager buttons to change tabs. I'm including the performance graph at that time for the CPU which is an I5. I have 16G of ram. Wonder if this is what Ciaphas was referring to.....
So the City does not get a supply track?
This screen clip is screwed up becasue the mouse was not responding as expected. Amount of ram used was 3.37.
Here is the graph while I'm working on my terrain riftval. It has only a single airfield and no other objects, and no paths. Notice I got a clean full screen clip using the mouse.
