OMG that texture popping is ridiculous.
It can happen once, and then it should be cached. If you turn right, and the right fills in, when you go back to look to the left, what you were just looking at, it should definitely not have texture popping.
I could understand it for any area / scenery you had not yet looked at, but if you were literally just looking at it a second ago, and your character hasn't even moved a single step, OMG!
That's totally unacceptable. They should have just made the game like the original Myst.
This is assuming of course that the user's experience displayed in that youtube video is the 'norm'.
I considered pre-ordering this game for about 5 minutes but figured BF3 and SW:TOR was enough of a gamble. Still considering Skyrim, but I doubt I will ever pre-order again, unless its discounted with free shipping from a place like newegg (my BF3 order, for example).
