Killzone Liberation

To select psp-1000 model goto 'settings' - then select 'system' menu and scroll down untill you see psp model :psp 1000
So far i'm using 9.9.1.250 (32bit) and have used the settings others have suggested and found it still runs at 17-19 fps or around 16-20% and sound very laggy other games work at 100% speed - has the speed been fixed on later builds?
