Config help for Kingdom Hearts

[Professor Pie]

Hello, I've been trying to play Kingdom Hearts on the 0.9.6 version and it tends to slow down/lags at certain times. I've played around with the settings but I'm quite new to this so I'm not too sure what to change.. Could any one help me with this please? I have also downloaded the new beta version, but it seems to be the same.

Plugins I'm using:
GSdx 890 0.1.14
LilyPad 0.9.9
Gigaherz's CDVD Plugin 0.7.0
SPU2-X 1.1.0

My specs:
Vista
AMD Anthlon 64 Dual Core Processor 5000+ 2.60 GHz
3 GB RAM
ATI Radeon HD 2600 XT

Thank you very much in advance.

Have you tried checking the "native" option in GSdx or enabling some speedhacks? (x2 cycle rate could help)

I've put on the speed hack and it's cleared up a bit of the lag but it still sometimes slows down. The audio seems to slow down with it as well. Do you have any other recommendations? Thanks.
