Paper Mario runs like crap!?

[Roland]

Ok, first off I'd like to introduce myself.
I'm Roland.
I'm no noob to much of anything (although I just started using this particular emu today)

Now, the matter at hand, I was searching the forums and the general consensus seems to be that Paper Mario runs great even on Low End CPUs.
So I am wondering why I am only getting between 11 & 15 FPS most of the time!
Settings listed below, system specs in my sig.

Emu version 3286
Dolphin IL used for everything

System Config
Enable Duo Core
Enable Idle Skipping
All Advanced Settings Enabled
Use Panic Handlers

OpenGL Plugin
FullScreen (640x480)
AutoScale
Native resolution
Antistropic 1x
AA off
EFB copy disabled (toggle with E)
EFB to GL texture
Use Safe Texture Cache

DSP HLE
All options checked

Individual game options
Disabled duo core


All settings not listed are unchecked. I am using the 1.3 SDL so that my triggers work for a few of the other games...
And also, it is Paper Mario US (NTSC)

Any thoughts, ideas, or suggestions?
Mario Party 7 runs great (slight speed increase if I disable EFB)
DBZ Budokai 2 runs decently (although slightly sluggish)
Wind Waker runs kinda sluggish (and of course there is no audio)
SSMB runs almost full speed (with the usual bg music randomly stopping)

It's not urgent or anything, it just has me like wtf!? cuz I've seen a report that it ran at full speed on a 1.6 duo core...
