The first video is a demo which was first shown at GDC 2013 and that demonstrates some of the PhysX features built-in to Epic’s upcoming Unreal Engine 4. The demo runs on a single GeForce GTX Titan.
The second video is about fur rendering used in The Witcher 3:
That fur looks so good
cant wait anymore… witcher 3.. wow.
Agreed Witcher 3 could be amazing if it doesn’t through away what was good in 1 + 2
