Very simple reason for that. NTSC updates at 60hx (60 times a second), so a game has to "generate" each new frame in time for the visual resync. If you can't quite manage it, you get jerkiness/irregular frame rates. If you can't manage an update every 60 frames, (i.e. 1 update to 1 frame), you drop down to 30fps instantly (1 update for 2 frames). Its better to lock at 30fps, than have an irregular frame rate most of the time (i.e. upd, frame, upd, frame, upd, frame, frame, update, etc...). If you target PAL, sometimes you can get better frame rates - if you can't "quite" manage 60fps, sometimes you can hit 50fps - so instead of runningat 30fps (NTSC half speed), you get PAL full speed (50fps). For NTSC your options are 60hz, 30hz, 20hz, 15hz, 12hz, 10hz (i.e. divide 60 by integer numbers). For PAL you get 50hz, 25hz, 16.6hz, etc.. ... The PS3 is *supposed* to be a hugely powerful console - visually at the least. I'm not impressed that ALL games on it don't run at 60fps. It either says the PS3 isn't as powerful as it should be, or that its too hard to optimise quickly (or both). Remember a couple of years back when Sony BOASTED that it would run at 100fps, dual output, 1080p?? Yeah right... "100fps will be the new standard for games".

Well, thanks for the info. Still, if the game plays well I'm sure I won't remember what FPS it runs at. Do you know what FPS elder scrolls runs at by any chance? I've played that, Resistance, Motorstorm, and RR7. If none of those are at 60fps then I'm fine because I enjoyed them all.
As far optimization...I'm sure that the next generation of games for PS3 will be easier to reach the 60fps mark because developers will be more used to the hardware. Like I said, Ninja Gaiden Sigma for PS3 will run at 60fps because the developer was very worried about attacks being delivered in the correct frame. I believe VF5 runs at 60fps as well for that reason and was their excuse for no online play (lack of precise frame animations).
