This year's Game Developers Conference is about to end today, leaving behind great panel discussions and announcements, and also a lot of other cool stuff that was not shown on any stream.
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!]
