Man, too bad hardly any of this happens to the effect at which it was "tweeted."
Really? You don't notice how you can see NPC's and monsters and little details like clouds and snow storms and forts and barrows from a much greater distance in Skyrim?
Seriously, play some Oblivion and then put in Skyrim. An NPC in Oblivion won't wind up on screen until it's not that far away from you. I'm gonna say maybe 50 feet. Also, look for Ayelid ruins that just "pop up" when they're maybe 100 feet in front of your character. Barrows and forts in Skyrim can be seen sometimes from (it seems) a mile or more away. In Skyrim, I'm able to fire arrows and fireballs at NPC's (and vice versa), even if they're way on the other side of a large river chasm.

I wouldn't even be able to
see these same NPC's in Oblivion from the same distance.
Pop-up was a fairly sizeable complaint in Oblivion, and Bethesda addressed this. I mean, mixing armor suits is nice and all. If I ever get the urge to do this I can always fire up Oblivion.
