We also have to consider that the real purpose and "special thing" of the "new" Creation engine is to "draw everything". It was because of this Bethesda didn't choose the id Tech 5 engine that Rage uses. We should therefore expect the draw distance to be huge for everything, yet we see pretty big flaws as I mentioned.
Id's Tech 5 engine wouldn't of been possible to use for Skyrim as it can't handle open world games, Carmack has stated this himself.

See all the hundreds of bushes everywhere and all the cactuses in Red Dead Redemption? Skyrim's environments surely are the most detailed in the history of all video games; Skyrim definitely draws more than any other game ever seen before.

You do realize the tech has to account for the highest denominator right? By this I mean the tech has to be able to handle the high density part's. With how the game work's it's not unthinkable to have hundreds of props on screen at once thus they have to plan the performance structure around that. So just because you can point out the tundra as an example surely does not mean you have true argument.
