I didn't really know where to put this since it concerned both TG and TG2, so excuse me if it's in the wrong place, or if there's already a thread like this.
I was looking at two test renders I did a while ago, one was from TG and the other from TG2. I noticed that a extremely simple scene if it didn't contain random towers, was relatively more realistic then another simple scene in TG2. I attached both of the test renders so you know what I'm talking about.
