Virtual Textures (aka Megatextures) talk (2008)
This is a remake of my 2008 Game Developer's Conference talk; I rerecorded it at home on the last day of the conference so that everyone could see it, not just those that went to GDC.

(By the way, why is it called "Sparse Virtual Textures"? Well, while the virtual texture can be sparse, it's mainly because at the time Microsoft was talking about an internal driver-level technology called "Virtual Textures" and I didn't want to confuse anyone by using the same name. As it turns out, I probably could have.)
