The impression I got was that instead of dynamically changing between a few different pre-made models for an asset at a specific point, it could automatically scale a very high quality and poly count model down to less quality (that is, generate the lower quality model automatically from the high quality one), and on the fly or maybe JIT, but I'm not sure if that's accurate or if that's also old tech. Edit: See your sibling comment, which came in just after I originally replied here.
