Forceware 91.31: Bug with 2x Antialiasing and DirectX (?)

Discussion in 'Nvidia' started by Nebelung, Jan 14, 2007.

    with Forceware 91.31 I've noticed that setting antialiasing to 2x causes only
    DirectX graphics to be stretched horizontally with factor 2 (OpenGL is not
    affected). All other antialiasing settings work perfectly, as well as AF.
    This stretching does not happen with Forceware 81.98.
    Is this a known bug?

    1. Just out of curiosity, does the horizontal stretch occur regardless of
    whether you set AA in the control panel or through an in-game option?

    2. Is there a reason you are using 91.31, rather than the latest 93.71? If
    anything the 91.33 beta drivers are an improvement over the 91.31 drivers,
    with many bug fixes.

    The stretch appears e.g. when setting AA to 2x via control panel and then
    starting dxdiag's Direct3D tests. The center of the spinning cube would then
    appear on the right border of the screen, thus only half the cube is visible.
    I don't have any games that allow setting the AA via in-game options, so I
    can't test this. However, DirectX games are affected by this stretch.
    The reason is just that 91.31 was the latest version shipped with my new
    FX5500 and 81.98 was shipped as an older version.

    Er, read the Release Notes for 91.31 and the subsequent releases to
    find out whether this bug was known to exist and maybe cured by later

    See the nVidia website driver section for the release notes. The
    driver archives (together with their release notes) are all accessible
    from the current driver page .
