Thanks all.

What exactly is a playable framerate?

    Not sure about that. I have a video camera which I can set to 30fps or 60fps and there is a noticeable difference in the video quality when it goes up.
    Frame rate doesn't affect the quality of the image as such, if anything the quality could drop as your not going to let as much light through to the sensor. Your software and display is probably not displaying the video at 60fps either. I have a camera that can go up to 120fps and you need specialised software to take advantage of the 120fps (and loads of light) and the advantage of the extra frame rate is in slowing down the video. If the video looks like it's playing normally it's more than likely playing at the PAL rate of 25fps as far as I know.

    You do know that a 120hz monitor runs at 60fps right? And 60hz LCD's are running at 30fps.
    Im pretty sure 120hz is 120 scans per second.. which would obviously mean 120fps. Hence why Vsync will lock the FPS at 60 on a 60hz monitor and why it locks mine at 120fps.

    With serious twitch timed gaming(near-pro level FPS etc), control input lag is a subconsciousness thing which I myself have experienced. But I don't believe anything above 60fps really makes a difference regardless of what people think happens. As Humans we just can't operate at a reaction speed below 150ms for anything.

    Really.. im no expert on how the human brain works.. but i do know that the difference between 60fps and 100fps makes a big difference in games like CS, from how smooth it feels, to practical things like recoil control and bunny hopping.

    This is a quirk of quake and games that use quake's game engine.
    In game physics are linked to fps.
    http://www.funender.com/quake/articles/fps.html (scroll down to documentation)

    Half life and half life 2 are based on the quake engine.

    2 hertz is equal to 1 frame in a progressive scan. Its a really common misconception in the gaming and TV world since LCD's became a standard, one which is really funny after all these years.

    If we were talking about CRT's, its a 1:1 ratio. But since it only updates half the screen, its not really worth talking about.

    He must have been taking about 60hz per eye in 3d mode.
    The very definition of hertz has always been cycles per second regardless of what you were talking about.

    Edit: actually Cuddlesworth's explanation also makes sense.

    Ahh my mistake... im talking about true 120hz monitors here. Which do infact equal to 120 frames per second.


    This sort of explains it.

    Well it isn't better "quality" per se but the motion looks much more fluid. It's a little odd too look at at first but there is a definite difference. I first noticed when watching back some of the videos because I thought they looked odd and I found that I had accidentally set it to 60fps mode.
