"Here’s my notes for the talk Streaming Massive Environments from 0 to 200 MPH presented by Chris Tector from Turn 10 Studios. He’s listed as a Software Architect there, and obviously has a deep understanding of the streaming system they used on Forza 3. This talk was nice and deep technically, and touches all parts of the spectrum." Very technical. But: if you can grok what's going on (and this is about at the limits of my simple understanding – could barely start to recreate what's described), it's very interesting about the challenge of rendering beautiful, high detail environments at a solid 60fps, mainly by pre-preparing a lot, and maximising streaming performance both from disk and from memory.
