    Im using a single 5850 in my build and I was wonder what Nvidia card I should use for for physx dedicated?

    and how I can do this.

    Nope. Nvidia drivers disable support for your PhsyX on your Nvidia card when it detects you're using an ATi card to render stuff.

    there are custom drivers for it, yes it is possible.

    google is your friend :)

    custom drivers could be an option, but I hate messing with that stuff.

    I might as well just say "screw physx" and just crossfirex my 5850. Like the tesselation will make a difference to me when im getting over 100+ fps :)

    Thanks for the help and knowledge.

    Ill put some research into it at least.

    Cheers

    Have you seen the list of physX games? It's not that large. If you already had a Nvidia card i'd say go for it. But (in my opinion) it's not worth going out to buy an Nvidia card just to play a few games with PhysX and have to go though the trouble of getting it to work with an ATI card.

    And? Does ATi's multiple screen function work combined with a Nvidia card? No, it doesn't and you'll need to seperate them.

    There are costum drivers, and you will never get the "perfect" Physx beacuse you can't enable the nvidia card's Cuda cores.. Also, i wouldn't bother buying it unless you find a really cheap one (and outdated).

    Physx is for nvidia, the end..

    you are right that it won't be as good as with just nvidia cards, however, you will still be able to use the feature and you will still get an fps increase, usually substantial so long as a decent card is used (8800gt or better). Physx is for nvidia yes, but it also works with an ATi card aswell if you know what you are doing ;)

    I really don't see the point of going through all that trouble to use a dying physics engine.

    I thought we're not suppose to talk about them because they're not actually legal.

    It is hardly dieing, if you look at the list of games with it there are alot brought out fairly recently.

    Deffinately not all that, but not dieing just yet

    Yea I thought we weren't supposed to discuss them because it is a grey area. Stating they exist is one thing though, discussing and providing the means to use them is another. If it turns out I shouldn't have said it I'll happily change it though

    Custom drivers are NOT illigal. Why? Because the GPU is every individual's own property, and it is therefore no restrictions on how it should be used. But keep in mind that using a custom driver can void your warrenty in certain chases.

    Physx is NOT dying. The latest Tech demo of Physx combined with DX11-tesselation has conviced many devs to rethink the purpose of Physx and how it can/should be used. Yet, it takes much time for people to change their habbits, and Nvidia must develop easier ways for other devs to adapt the Physx technology..

    It isn't the hardware that is illegal, it is the software. The drivers to make it work are edited drivers from nvidia and ati and I'm fairly sure it has some code from physx in there too. All of which are owned by the respective companies. You can't just take a piece of software, modify it, and distribute it without the original creators consent
