Clockwork Unicorn.9617

I've been having the same problem since Saturday afternoon.I play on a laptop, so it is not super high end, but the game always ran well and with few issues. I've tried: rolling back the main .dat file to a September back-up and updating, clearing the cache in AppData, installing the new nVidia drivers (to 388 from 384), and updating Windows 7. My character models are set to Low. None of it helped.Now, here's the thing. I get 50-60 FPS and everything is alright while I'm doing "simple" things, like gathering in my home instance and dailies. The moment I have to fight, it drops to 5-10 FPS and becomes a slide show. I ran the diagnostics and it looks like the game keeps using the disk (I can hear it turning on and off the way it really, really should not). I'm afraid to play the game any more at this point, and it really sucks because we've got a new episode coming tomorrow. I hope there's a solution to this. The problem is completely new and very confusing.
