Hi guys,

Here's a sample scene using a new feature we're working on- Screen Space Ambient Occlusion. aka SSAO. For more information on SSAO, check out:
http://en.wikipedia.org/wiki/Screen_Space_Ambient_Occlusion

SSAO, using screen depth information, helps define 3D details in your scene without the use of light maps or regular ambient occulsion maps, thereby saving both texture memory and preparation time.

You can adjust the sliders to see the effect with or without SSAO and/or textures. Give it a try & let us know how it works for you. If it doesn't please let us know what you are seeing, what kind of frame rate you are getting, and what your hardware is.

thanks!
