I'm in the process of doing the Forbidden Legend quest and I'm experiencing a significant amount of lag. I'm on a 360 and this is the first time it has been bad enough to where it makes the game very difficult to play. I've looked on the internet but can't really find anything about whether or not lag is just tied to this dungeon/quest. If it is not, what do I need to do in order to get the game running like it has been for 700 plus hours?

A couple of things I've thought about may have nothing to do at all with it but I've considered whether or not the number of saves has any impact on it. I'm over 1,000 saves right now. Also would clearing the cache do anything?
