Yes, they slow it down quite a bit. And then I get pissed off and want to throw my computer out the window. But I am too lazy to take them out when I'm not taking pictures.
Aww, damn, this is discouraging! Well, not really, but your cities are way better than mine! But this is a good thing, as you do well in inspiring others, like myself! Your incredible cities make me want to make more.

BTW how do you make the streets so perfect? That is my biggest problem so far.
