I'm currently working on the main quest and I has a MASSIVE horde of guards hanging around a single house. Whenever I go into Bruma I have a serious drop in framerate.
i can't remember off the top of my head all my mods but here are some:
All the DLC's
Oblivion Banking
The wichking's Sword
The wichking's helm
Shiroi Tensa zangetsu
Tensa zangetsu (off hand one)
Hoar Frost castle
And thats what I can remember.... if you guys know of any fixes please tell me..... my video card will burn out soon
Cheers Thraal
