    That's because it has been warped and has had offspring sung off it.

    The real microstuttering is what is described in my quote. It is a perceived FPS that feels much lower than the reported FPS. Nothing more, nothing less.

    Anything other than that is simply 'stuttering.'

    How does that even make any sense. You cant perceive a framerate higher than refresh.

    Nice review, ether.real. I give you props for being one of the few who are willing to push the card a little with the settings. Love the Crysis bench and hope I can expect the same when mine are up and running this week.

    are there any samples or reviews floating around of it? seems it was announced same day, though i haven't seen or heard much about it in my net meanderings... would be interested to see the performance difference.

    I think by "It is a perceived FPS that feels much lower than the reported FPS. " he means that if you have 4 frames rendered in a second, frame 1 and 2 will come at you very fast, then there will be a short gap, and frames 3 and 4 will be displayed in quick succession. so it seems like both pairs are a single frame, creating the illusion that you are getting 2 fps rather than 4.

    So wouldnt Vsync fix all that?

    I've never used crossfire or sli myself, but i dont think you can use vsync with either. It should give a high enough framerate that you dont have to.

    i would have thought so
    as long as it remains at 60fps anyway i know that when playing quake4 with x1900 crossfire while a 60fps it was smooth as silk but the moment it dropped below 60fps it started to feel like 15fps despite being somewhere between 30-60fps
    im guessing this is what everyone refers to as micro stuttering
