There have been many reports claiming of issues with textures in Skyrim when the game is installed to the Xbox 360′s hard Drive and now Bethedsa has acknowledged this.
Posting via Bethedsa’s official forums, the developer said issued the following statement:
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.
We have to say that having played through the entire campaign on Xbox 360, all while the game was installed to the hard drive, we didn’t experience any such issues, maybe we were just the lucky ones.
