ATI Radeon Newbie Quick Question

    Only had my Radeon 9800 Pro 128MB for 1 week now. My first ATI card in
    many years. With my WinXP PC, in Device Manager, the card shows up
    twice....once as Radeon 9800 Pro, and once as Radeon 9800 Pro
    (Secondary). ATI Tech Support said this was normal. OK, no problem.

    But, when configuring all my 3D games, you have to select a video card.
    Both the Radeon options show up in the lists. In all the games, the
    game itself defaulted to the 2nd card, which was Radeon Pro (Secondary).
    Not sure if there was any "intelligence" at work, in these automatic

    Does it matter which one you select in your 3D games, i.e., Primary or
    Secondary? Should you always select the first Radeon? Appreciate any
    advice. I don't know why this question isn't answered in the
    documentation provided with the card, or on ATI's web site. Thanks.

    What games are we talking about here? Can't say I've noticed
    anything asking me to select primary or secondary. Which is
    possibly why it's not addressed.

    I believe the point of having 2 devices is for dual monitor
    support, I would've assumed selecting 2ndry without a second
    monitor would have left you with a blank screen, obviously
    not the case, but if it's working why bother fiddling with

    Thanks for the info. Sounds like everyone tends to choose the first one
    (if choice is there). The games I'm referring to are MidTown Madness,
    Midtown Madness 2, Star Trek Bridge Commander, and one of my demos (I
    think the Unreal 2 Demo). In most games I've played, when you set video
    options, one of them is to select a video card. The choices are
    normally the name of the actual card, or "default video card", which are
    usually one-in-the-same.

    But wasn't sure on the Radeon, since it's listed twice, because Device
    Manager shows 2 cards...1 primary and 2 secondary.

    Anyway, the main reason I ask, is because I tried ST Bridge Commander
    for the first time using the Radeon 9800 yesterday. It had chosen the
    2nd Radeon for the graphics card. I didn't think it mattered, so I left it.

    After 5 minutes into the game, I got an error "STBC.EXE...yada-yada",
    with option to send error to Microsoft. Never happened before with
    previous GeForce4 Ti-4600. I'll reset the graphics card to the primary,
    and see if I can get this game to run without any errors. Hope so, cuz
    this is one of my fav games. Thx again.


    p.s. FWIW, just ran first AquaMark benchmark, score of 44,027 with
    default settings. I guess that's somewhere in the middle. I think the
    higher scores were oc'ers, cuz their CPU scores were way high.
