Final Fantasy IV : The complete collection

[FFFanatic]

Hey guys I'm new here. I have downloaded the newest PSP emulator here and while I can play FF4 without much trouble, I noticed when Cecil uses the Blue Fang at the beginning of the game, it causes some kind of lag or slowdown during the lightning animation and goes right back to normal speed. The emulator is at default settings as of now.

Is there a setting that you guys recommend that will stop the lag on Blue Fang?

I think it also sometimes lags during the Mist Dragon fight too but I've yet to test it further than this
