Doesnt K2 already run in a much too low framerate anyway?
Edit: Sorry, that was a bit short and sharp. My point is that the majority of games, including Killzone 2 I believe aim to have a framerate of about 30, but it occasionally drops below this if a lot is on screen. This is a tradeoff to allow more graphical effects than the same devs could get if the game ran at 60 fps. Now most gamers are willing to accept 30 fps, but I doubt many would accept 15. (I personally consider 59 fps or lower to be undersirable and would prefer the resolution or amount of effects to be dropped instead)
