Help with black lines across my screen

    Hi there, when trying to play games that normally run fine on older
    graphics card, i.e. medal of honor allied assult, i get black lines
    dart across my screen so that the image breaks up every now and again.
    It also happens with harder to run games such as Call of Duty 2. Some
    of my mates say it could be concerning vsync, is this the case and if
    so how do i fix it, also if this isnt the case what can be done to
    prevent the black lines. My graphics card is a NVIDIA Geforce 6200.

    Many thanks in advance, a well frustrated gamer

    Turn vsync on and see if that helps. What you're probably seeing is
    tearing/shearing due to the game refreshing the screen higher than the
    screen refresh rate, but not enough to be double. This results in a tearing
    effect where the top part of the screen is slightly offset from the bottom,
    and sometimes gives the effect of a black line across the screen. It'll be
    most noticeable when panning (moving the image from side to side) in the
    games. By enabling vsync it'll ensure that the screen refreshes from the
    game coincide with actuall monitor refreshes so avoiding the tearing.
    However, it can decrease gaming performance as the new refresh rate will be
    based on the fractions of the monitor refresh rate setting (1, 1/2, 1/4
    etc). With a 6200 card, the bottom end of the performance in the 6xxx
    series, you might well find that this is the case. Try it and see.
