    it is useles indeed
    if you own a physx card then you have the driver installed already- maybe even a newer version
    if you don't have one you won't need the driver

    I uninstalled the drivers
    Absolutely no problems

    Uninstalling Ageia PhysX drivers will not effect your game in anyway.
    (Unless of course, you have the card, then I'd recommend keeping them)

    EDIT: \/\/\/\/ Nah, just unchecked the option for hardware physics. I guess the roundabout point I was trying to make was that if disabling hardware physics acceleration doesn't make a lot of difference, then the software must really be doing a TON of the work, and that makes sense to me. If I were a developer implementing PhysX, I'd bank more on the software doing the work before I'd assume the end-users would adopt proprietary hardware to do it.
    It's either done in software or done in hardware. When you turn on the hardware, the Ageia PhysX card does the work. This reduces the load on the cpu. Typically, you will see up to a 15 fps increase on higher end systems on the standaed maps. You cannot play the PhysX maps, lighthouse, tornado, or heatray without the hardware. Well, maybe the heatray PhysX mod if you have an ultra high end system.

    As far as uninstalling the stuff that came with UT3, you could uninstall it and see if the game still runs. Is there a reason you need it gone? I would think that it's there for a reason, unless it's a working UT3 version of the hardware driver because the drivers that come with the cards do not work.

    yeah you only get use out of it on the physX enabled maps like tornado

    It makes a fair difference if you play on PhysX heavy maps, such as CTF-Lighthouse.

    did you uninstall the drivers?

    Ageia PhysX: is it needed?

    Anyone Uninstalled the PhysX drivers bundled with UT3? I've heard that it doesn't affect how UT3 performs. Maybe it only does something with the PhysX cards.
Working...
