Hi, I have an athlon 64 3000 running the 64 bit version of windows xp (I know, I know, it's unsupported) and haven't had any performance issues until I reached Ember Light Path.
I was achieving approximately 30 fps the whole game with full detail on and anti aliasing at 4x. Now that I am in ember light path I get around 10 fps, and 2-3 fps while fighting and I get no performance increase when I set the detail to the lowest settings. I cannot continue playing this way. Anyone else have problems with Ember Light Path? When I move to any other location besides the fire island the game runs fine.
Can anyone think of any technology used at ember light path that's not used anywhere else? Anyone else have issues with Ember Light Path?

Try installing those drivers though, it might help even on 64bit.
