Hi Frank, I noticed that too. When I use the curves as they are in the material, and have max displacement set at 0,1 I can use a ratio like 10 tiles horizontally and 4 rows per polygon approximately. Above that I get shading errors. Not to forget that the quality of the SDS object is set to 3. When I first built the roofs I used Nurbs objects. I noticed that SDS support for displacement is mucht better. It's a lot faster and needs much less polygons.
It has been a good research for myself too. I replaced all the roofs of the block of houses and it's much easier to handle now. Wireframe is a lot lighter and renders much faster.
