did you add a profile for pcsx and bound the correct exe file to it? Also have you gone under AA compatibility settings and selected vanguard? I was messing around with it a week or so ago and it was working then.
4th pic under AA Compatibility select vanguard. Also it looks better if you keep the internal res relatively high as well to begin with as that smooths it out some to begin with. I usually have it set to the screen res as well unless high internal res has issues with the game.
Play around with the mixes of internal res and AA modes to see what you like best. I tend to lean towards the mixed modes. 8SQ looked really good on Persona 4 too bad it took the framerated down to about 20fps.
Kebrus, thanks bud, makes sense now... I see how the internal res works better now! Why do the guys not make the internal res easier to use properly by making it match your layout?
Most people probably use square resolutions becuase the defualt non-native res is square. The only difference is you get a little more of an effect AA in one direction then another.
I set everything to max, which included 16QxAA, 16xAA, Supersampling etc. As you can see it all works fine, setting through the nVidia control panel, I dunno why you need to download nHancer...
