Just downloaded PSX2 latest release, using USA bios 2.0
Windows 7 Ultimate 64
Intel C2Q @ 2.4ghz
nVidia GTX 260 superclocked 216 896MB
Corsair DDR 2 6GB RAM
I have all the settings on stock and the game is lagging heavily during sequences and has other serious hiccups while playing.
Is it possible to play around with the settings to be able to use PSX2 at PS2 frames or is this emulator primarily CPU based? And if so, does it utilize multiple cores or not?

I've determined that my CPU is bottlenecking my performance. I'm thinking of OCing it but I broke some clips on my heat sink when I built my tower and it doesn't stick as closely to the CPU as it should (heat is much higher than it should be).
I noticed that EE is always at 99% while my GS has topped at 40% during max game load.
Frame rates have dropped to as low as 34.
If I overclock to 3.0ghz will that be enough to run the last gen of PS2 games like .hack gu series? If not, what is the recommended CPU speed to run all PS2 games w/ a breeze.
When trying to judge how an overclock will do with PCSX2, it's almost exactly the same as the overclock amount.
That is, if your CPU capped at 40FPS and you managed 25% overclock (roughly the amount of 2.4ghz to 3ghz) you can expect a 25% FPS boost (or 50FPS).
The .hack//gu series is pretty demanding, you can expect to still get slowdowns at 3ghz in a lot of situations.
1: set the affinities to TWO cores, and make sure it's set to high performance
2: speedhacks are not required for 0.9.8 for anything 2.2 or higher (I would know, I have a 2.2 and I get full fps)
3: try setting the clamps on EE and VU to NONE
^Did the above and I experience heavy lag without the speedhacks.
With speedhacks on (50% load off CPU), native PS2 solution scaling, and removing the clamps the lowest FPS drop I'm getting is around 40 in the busy areas.
Within rest of the game it's playable but not smooth and fast.
VU cycle stealing will give you the most FPS boost in the //gu series but setting too high will cause both slowdowns and odd model glitches.
