When Nvidia wants crap to break apart, it breaks apart good. This is is a real-time dynamic fracture demo shown at GDC, running at 30 frames-per-second on a single Geforce GTX 680 graphics card. Ever wish you could spend money on a tech demo? [Thanks, Zak!]
The dust looks a little... awkward. I dunno, I'd prefer standard non-physics sprite dust over this, it's ugly.
It looks like the dust is a few hundred thousand times too large, bounces like a tiny dustball in a weird fashion. Is this dust or tumbleweeds?
