Because they are claiming an increase of detail by a factor of 100,000, while the demo barely showed anything close to a detail increase by a factor of 1. Trees & rocks are often animated in modern games, so animation is important. Additionally there is no point using a heavy duty voxel engine to render background landscapes that no one will visit in the game, especially if it's going to take gobs of RAM & CPU time to do it. Hardware tessellation can already greatly increase surface detail, is already available in modern hardware & has better looking demos. http://www.youtube.com/watch?v=4G9anRoYGko http://www.youtube.com/watch?v=4G9anRoYGko http://www.youtube.com/watch?v=gT_45RFFTx8 http://www.youtube.com/watch?v=gT_45RFFTx8 http://www.youtube.com/watch?v=0HWZKGZcKoA http://www.youtube.com/watch?v=0HWZKGZcKoA
