Pcsx2 FFX help

[Muze]

Hey there im new here and to all of this so bare with me.

I recently downloaded pcsx2 0.9.8 and got my bios and made an ISO file from my FFX disc and ive tried everything i can think of to get the game to run at 50fps but for some reason the best ive been able to sustain is about 25-30.
Can anyone suggest how to make it run faster?

My pc specs are:
Intel(R) Pentium(R) 4 cpu 3ghz (2 cpus)
Windows 7 ultimate 32 bit
2048mb ddr2 ram
Ati radeon 9600 series

Pcsx2 settings:
GS: gsdx 4600(msvc 15.00 sse2) (also tried zerogs kosmos 0.97 but found it ran worse)
Pad: ssspsx pad
Spu2: spu2-x r4600m
Cdvd: linuz iso
Usb: usbnull
Fw: fwnull
Dev9: dev9null

Speed hacks:
Ee cyclerate: 3
Vu cycle stealing: 1
With all other hacks selected (mvu flag hack, mvu block hack, ensble intc spin detection, enable wait loop, enable fast cdvd)

Any help would be much appreciated
