Well, I'm gonna let you know that you do have a fairly weak system for PCSX2.
First, you'll want to make an image of the disc with ImgBurn
. This can affect performance.
Use frame skipping if you must, but I wouldn't recommend it, personally.
Using a software renderer will likely be very slow, since your CPU does have a pretty low clockrate (1.8Ghz). Stick with the hardware renderers. Direct3D10 is usually better than 9.
Be sure and set a low internal resolution (i.e. check the box for "Native
"). A Radeon HD 3600 isn't that bad, but let's not complicate things for now.
Apply Speedhacks until you get a decent enough speed (if you can), or until the game starts acting worse (a.k.a. the game "breaks"). You could try the Preset
options for ease of use.
Do not be surprised if you can't achieve/maintain full speed.
