games stutter, and psp2 grapic problem update

[DustyBlaze]

ok hi all,i am kinda new here but i want to see if anyone can help with few things. so first i want to know how to get my emulator to start running smoothly again. the reason why i say again is because when i first got it on my computer ( i play on the pc ) it ran smoothly, no problems ya know. then i had gotten phantasy star portable 2 and i have the problem where im walking through the floors, so i started messing with the settings now it runs kinda sluggish and it stutters now....i also wanted to see if anyone has found a solution to phantasy stars little graphic issue. i play the 1st dissidia and phantasy star the stutterig happens on both games.
