Why my model is blinking?

I’ve downloaded a model here: http://tf3dm.com/3d-model/the-city-39441.html and imported it to UE4.8
I don’t know why but it blinks in my scene (a video below). I’ve tried to change a material, change the size, rebuild a project.
How to avoid it?

I’m using GTX980, i7 i3930k, MacOS X 10.2, UE 4.8.

It looks like z-fighting, a pretty common issue with game engines, if 2 faces are right on top of each other, they will cause flickering like that. The easiest solution is to avoid having over lapping faces like that.

Is this problem in the model or in my scene? I’ve tried to lift the model up, over my scene to avoid its overlapping with my scene but it doesn’t work.
Can it be that my GPU is broken?

It looks like it’s just an issue with the model itself having overlapping faces.
