Mixy, Here's an update to my post earlier with that screen shot. You might like to know I have an Nvidia 460 graphics card in my computer and the 3D renders very quickly for me.
The only thing I notice once in a while is that some elements do not render on the first try, but they always do on the second try if I select the 3D button again right away.
An example from my screen shot of something not rendering would be a piece of the black road or the blue water. It's not a big deal to me, but I thought you would like to know.
Great program!
