Interesting. I'll copy your settings as I got the same card as you, but I could never get full FPS. I suffered serious slowdown in combat so I never bothered playing it on JPCSP. Just sucks that the cutscenes aren't on the big screen 
Hah, your settings worked as a charm. Gained double FPS during the intro cutscene. Let's see how the rest looks like.
