... If you remove nanite from this demo, this demo would be below average.
Again, this is just a weird take. I don't know what this is trying to prove. Sure, if you removed nanite you couldn't have that city with basically infinite draw distance and near perfect lod scaling. Is that supposed to be a knock, or is it just illustrating how great the technology is? And the reality is, it does have nanite. That's the whole point of tech demo.
