Speaking of Quadrion Engine, it's a large endeavor that Shawn Simonson, Renato Ciuffo, Kieran Culliton, and I have been working on for a few years granted my input has been a bit variable.
Lately we've been making immense amount of progress as Shawn has implemented a dynamic lighting system which uses a defered approach.
What follows is a video showing off the SSAO and dynamic lighting working simultaneously. On my 'acceptable' GeForce 9500M (mobile) 512MB I get about 45fps on average which is damn good considering you could conceivably have an unlimited amount of dynamic lights on the screen and not have much of a performance hit (if at all) though I'm not sure about overdraw.
Anyways, enough of that here's the video WATCH IN HD, it's set to Synchronicity 2 by The Police =D.

Also, don't forget to check out Moogen Studios which is our development blog. I believe Shawn's going to be make some video blogs in the very near future, so those that are interested in some technical details and theory you'll soon find yourself indulged; he's a great speaker.
Peace
