Improvements:
Ambient Occlusion: Post Processing Filter
Allows adding much more realistic dynamic shadows to scenes.
Advanced Character Lighting
Much greater contrast, much greater specular lighting, and much more detail on characters can be seen.
High Density Crowds
In video it shows over 100 locusts running around.
Dynamic Fluid Surfaces
Can you say wow at the water? Video of it is amazing. Realistic water physics simulation, realistic specular and environment reflections bouncing off the water, more dynamic interaction with water, sound effects, splashes, etc.
Matinee Improvements
Used for in-game Cinematics, interesting tool.
Soft Body Physics
Realistic interaction with soft bodies. Video shows a cube of meat, an elastic watery substance. Very organic.
Destructible Environments
Real-time structure analysis tools to make destruction realistic. Looks good.
