Slow motion movement - not an affinity issue and it's driving me insane!!

[Bleepblurp]

I installed Titanium on my Dell XPS (WoW Edition) gaming laptop. The laptop runs Windows 7 64 bit. 4 gigs of ram, dual geforce 8700 vid cards (but I'm only using 1 for EQ). Duo core processor, but I use EQplaynice so I'm using 1 cpu.

For some reason I can't play EQ. My character moves around in ultra slow-motion, but sometimes he moves fine. It's always in the same areas. For example, I can run from T2 in the tunnel all the way to the entrance just fine. However, if i turn around as if I'm running back to shady, it's insta slow motion. Casting spells is like molasses, other players running by me look like they're running on the moon. If I move to the right side outside of the tunnel and look west, I can move and cast fine. If I face WFP, slow motion. Certain pockets in the tunnel I can move fine for a few steps. It's always in the same spots.

I've tried changing my max FPS to all sorts of settings, and syncing it with settings in EQplay nice. I've tried not using EQplaynice and manually setting affinity. I've lowered all my video settings and turning all particle effects off. I've changed my compatibility mode to windows XP. I manually turned off all new models in the options thing before I logged in. I thought about trying a new UI but haven't. I don't see why I'd need to, because I can play P99 perfectly fine on my desktop that's slightly better than this laptop without jumping through any hoops at all. It just works.

Help!
