''Skyrim uses a lot of dynamic streaming systems, including textures. We’ve seen a few reports of certain textures temporarily scaling down on the Xbox 360, and not scaling back up. We have verified that this issue does not occur when playing off the disk and when the game is fully cached (not installed). Skyrim makes heavy use of the Xbox 360 caching system, and caches over the normal course of play while in menus or interiors. This cache can be wiped when other games are played or when the user manually removes it. We’re working on a solution in the next title update for those who have installed the game. ''

Thank your for new information we really needed it...
But i am sure people already said cleaning cache does not help with this.
Also people are reporting that playing from disc also creates this problem.
Did you mean that those who play from disc should remove caches too?

I assume that was the post Gstaff deleted? If so, thanks very much, I'm sure the community will appreciate this for reference.

Post is on top of this page, it's up again.

Good to know that Bethesda is on top of things.

Last night while I was playing the textures looked pretty awful, but today they look great - other than some of the snow-on-rock textures. Not sure what the issue is as I haven't changed anything since yesterday(playing straight off the disk).

At least they are onto it!

TBH as long as i know they are working on it i am fine
