Sorry? Not working? It looked quite perfect to me! :-))))

Very well for me 30fps and even more - the trick seems to be, when you're 
flying over such a ball, there isn't much of the terrain in-view.

Is quite smooth for me ;-)

But what will happen if there are several spaceships flying over that ball - 
how will that (and lasers, and explosions etc) affect it?

I have to complain about memory usage on loading time again - the memory 
usage seems to have increased even more?

I might have to install a bigger swap partition soon? ;-))

In-game: no swapping

It looks absolutely great! That's the overkill!

As the wise man said: best would be both

flat terrain for big planets
and that nice super wrapping for small/medium asteroids - that will be great 
in the game!!!!
