Thanks for all the ideas. So far nothing has fixes it, though I have thought of attaching an objextg over the flicker, like a docked shuttle. .For the flickering the street. I can just fix that with a simple plane. I will look into Blender. I thought I could fix it by checking "no hidden" on the DAZ export. That didn't work.

I couldn't stop it, but I did subdue it. Here is how it looks now.

The link is no longer available and I know it's an old topic. But I ran into the flickering texture thing in my project due to overlapping objects. I lowered one of them a little bit and voila, no more flickering. I wouldn't have come up with this simple solution without you, so thank you.
