Thanks Thomas, I am aware of that method.
I have made a series of renders for comparison.
The first shows just a part, it is renderd 3 times the original size:

Looks rather nice.
The second is that same render scaled back down 3 times:

Just the way I want it!
These first two are with adaptive antialias.
The third is rendered original scale with antialias set 3 times:

Very ugly and distorted indeed.
The fourth is also with antialias set to 3, the difference is that
all nurbs objects are individually changed to polyhedrons.

I also rendered this without antialias, with the same result.
It is a good exmple why I avoid converting nurbs to polyhedrons.
Nurbs resulotion was set to 1.
