Performance suggestions for LotRO, Book 11

There's some discussion on the IGN forums about how to improve performance in Lord of the Rings Online,Book 11. The poster suggests that the method "made the game run as good as it did when I first started to play".

Overall, there's some question as to the overall efficacy of the method, which is to move or remove all the files from My Documents\The Lord of the Rings Online, including the settings file (which will of course be set back to the defaults that you had when you first started to play.

Perhaps there's a saving to be had by moving or removing large numbers of snapshots, however my own experiments didn't bear that out. Instead, I'd suggest setting MultiPassLighting=False in UserPreferences.ini if your LotRO frame rates are suffering.
