That’s literally how every 3d game works (barring a few procedural games maybe). Now they just stream those texture and meshes as needed and presumably cache them.

Don’t get distracted by this terrible piece of an article. It never states how long this peak was. It could have been just 100ms. So interpolating this to 81gb/h make no sense at all. It’s just pure click bait.

In the end only the total volume downloaded matters (which the article of course doesn’t mention). Why wouldn’t you want to receive that as fast as possible?
