It is a well-known Elder Scrolls V: Skyrim bug that if you install the game onto your Xbox 360′s hard-drive, some in-game textures might look a little funny (well, that and the several other glitches and issues that have popped up so far). The answer to your problems appears to be in sight however, as further to our post on the issue just over a week ago, a patch designed to fix this annoying issue and others is on its way for sure, and even has a definite release timeframe.
Pete Hines has confirmed via Twitter that the patch will be released to the masses (on PC, PS3 and Xbox 360) in “the first half of next week” – meaning, the first half of this coming week. On that basis, I think it’s safe to assume you’ll finally be able to install Skyrim onto your Xbox 360 hard-drives by this Thursday.
The official patch notes have not been made available yet, however the patch will also fix the performance issues that some PS3 players have been experiencing. Given the amount of other in-game issues and glitches that are being discovered on what seems to be a continuous basis, it will be interesting to see what Bethesda have been able to include and fix this time around.
