pcsx2 have launched their 0.9.6 version which is much more compatible and is capable of playing playstation 2 games at better speed on a decent rig....
i tried wwe smackdown 5 dvd on my quite average machine (amd turion X2 1.6, 1gb ram, 256mb nvidia geforce 6150) n got about 40-60fps... other games mite run better n even more if config is more...
the website

Enjoy~!
