I haven't been in the loop for the last 2 months and I was wondering if the user community have released an unofficial patch regarding performance hits within certain areas of Skyrim such as the Thieves Guild, certain dungeons, and other areas where you run into a large performance hit.

I only ask as I know the Creation Kit has recently been released.

Last I heard they're not going to start on the Unofficial patches until Bethesda says they'll stop patching the game.

Bad news, quite understandable though.

Not necessarily. The Unofficial Buglist will continue to be maintained and the unofficial bug tracker will remain available for Bethesda to track issues. Issues from the unofficial bug tracker are sent to Bethesda on a weekly basis. Some of these issues have already made it into official updates. As for quest fixes, these should only be addressed in an unofficial patch as the last resort - if at all possible these should be fixed by Bethesda.
