Finished Persona 4 with it, not too bad I would say if you configure the settings correctly.

Used Gsdx 883 with SSE4 output, make sure enable Logarithmic-Z.

CPU settings = EERec, VU0rec, VU1rec, MTGS enabled.
Use VUSkip
Custom FPS Limit = 60
Skip Frames when lower than = 55
Consecutive frames before skipping = 0
Consecutive frames to skip = 4

Frame skip will prevent massive slow downs for battles, town and music. (Very annoying especially when the music slows down according to the fps on screen, so frame skip for me locks the fps at 60 but choppy abit)

Most crucial of all is that under Advanced, make sure u enable Flush to Zero and Denormals are Zero for both EE Recs and VU Recs. Under VU Recs, Round Mode set to Chop/Zero. If you don't, the battles in Persona 4 will keep looping over and over.

So basically these are my settings that allowed me to finish Persona 4. Gonna start New Game+ soon . You can cheat during Arcana Chance using PCSX2 lol.
