Help please! the animations like flames and doors opening and closing lag. I've tried returning to an earlier save but eventually they start lagging once more. so far its only this one character. I've made sure my video drivers are up to date. any suggestions?

What video card? What drivers? What CPU? How much RAM? Which Windows version and Service Pack? You omitted the standard summary of hardware components and the Operating System environmental information.

How many hours is your save game? Cause this sounds like the http://www.uesp.net/wiki/Oblivion:Technical_Support#Stuck_Door.2FSlow_Framerate_on_Some_Animations. If you are on the PC then there are fixes for it.

Thx. the ABOMB fix worked.
