Don't think so.
I guess you have it as far as it will go.
I can't see to infinity on mine either.
When the program was made computers weren't that powerful and many people had to upgrade their graphics just to run it at all, then it was a trade off against massive lag. Presumably the makers limited it.
Also (unlike Caesar IV) it has no "backdrop/curtain" or whatever it is called. At the edge of the map, you just see over the edge of the world into black void. Not exactly realistic anyway. The fog at least hides this until you get close to the edge.
