PCSX2 settings? Plugin settings? What FPS did you get?
30FPS i download **** PCSX2
What are the plugins you are using, how they are configured, which speed hacks have you attempted (if some)?
That game is known as demanding and trouble maker albeit I can't tell more because don't have it, still I'm almost sure you'll need to configure the emulator to use some hacks.
But, 30FPS is in itself a symptom you may have the vertical sync enabled in the catalyst driver, try forcing disable it.
PS: My machine is almost the same as yours, it's able to run most PC games full quality, but we are talking about emulation here and a demanding one. Some games run without problems and without need of hacks and some will lag badly, especially those who do not respond well to the speed hacks.
