ATI 3470 mobility, WoW is extremely jerky, almost unplayable.

[DanTheMan]

My specs are as follows:

Acer Aspire 5920g:
- Processor: Intel Core 2 Duo T5750 2.00GHz 2MB Cache (667MHz FSB)
- Graphics: ATI Mobility Radeon HD 3470 256MB
- Memory: 4GB DDR2 RAM

I'm getting around 25-30fps on WoW with the very lowest settings and it's so jerky that it's almost unplayable.

Coming from a system with a 256mb 6800gt and only 1gig of ram that played WoW at 1920x1080 with ~50fps, I expected more from a system with 4x the ram, more processing power and a graphics card that at the very least should be on part with the 6800gt. I'm only running at 1280x800 aswell.

Any ideas what could be causing it?

It runs ok at lowest settings with 1x multisampling now, It's definitely any sort of AA that ruins performance with this card.

Pity it looks crap.
