The functionality of CUDA and its implementation of GPU-accelerated PhysX processing has benefited many a GeForce user. Users of ATI accelerators lacking this incentive either use Ageia PhysX card or avoid it altogether. It has been verified by Hardspell that in an environment where Radeon accelerator(s) do graphics processing, a GeForce accelerator can be used standalone to process PhysX. Hardspell used a Radeon HD 3850 along with a GeForce 9600 GT on the same system with the display connected to the Radeon, though no form of multi-GPU graphics connection existed, the GeForce card partnered the Radeon well in processing physics, while the Radeon did graphics. Results of the oZone 3D FluidMark, a benchmark that includes routines to evaluate the machine's capability in processing physics, showed a greater than 350% increase in scores, showing that the GeForce accelerator is doing its job.

Well this is good use for radeon owners. i expected the drivers to conflict with each other, something wrotten.
Still begs the question whether or not it is needed. I have considered myself getting a cheap 8 series gfx card for physics, but so few games use them, it only seems to be benchmarks that truely benefit. :(

so, would a 9500gt work too? or do we have to pay 150 bucks still just for physics?

So could I throw a 9400GT in with my 3870 CF setup to get some PhysX support? I guess that would be cool!

this is great news...but we need some more details...what motherboards are applicable, drivers needed, which video cards can be used (can older Radeons be used, or lower capacity Geforce 9x00 series), etc.

I've been waiting for this as I have mostly used ATI/AMD graphics, but pondered how to implement physics going forward. Can't wait to see how this unfolds.

Now one has to ponder - on a dual pci-e slot board, is it better to go crossfire and take up that second slot with an equally priced video card as your main, or is it better to take a cheap nvidia card and get physx capability....

hmm.

Hopefully someone will figure out a way to do this on Vista. Otherwise Vista is going to be bashed again .

This is gonna hurt Microsux......more people will just put off using Vista......there are an aweful lot of gamers out there in the Big Wild world.....but noone on a multi GPU Physx setup is going to be playing DX10 Physx games once more of them are made :eek:

Just buy a 200 series card, a 2nd card does not add anything to Physx as the 200 series has CUDA 3.0.

One question.... If this only works in XP can you still run a pair of ATI cards in xfire and have a 3rd card, the nvidia running PhysX?

I think XP only supports 2 GPU's. Thats the main reason I went to Vista so I could run the 3 3870's together.

I have a Asus P1 PhysX card in the closet, but not sure it will work in the same way...

To me thats pretty simple. Vista and Xfire. Think of it this way:

How many games will benefit from Xfire, vs PhysX...?

In a year you may get your answer if the Nvidia is to be believed. They said, 25 games before Christmas, 30 in first half next year .

Thing is PhysX adds extra dimension to the game, while all xfire does is give you good framerates .

Physx is just a standard. Any game can do its own physics, its just cheaper to use an engine and library which has already been done for you. I see more games using the haok engine, which is hardware independant.

maybe , but I dont see software physics doing what physX can do . Like cause the cloth in GRAW to shred to individual pieces, you can shoot individual planks in a fence and take cover . Adds an extra dimension to the game .

look at the videos here

Yes, you can still run a pair of ATi cards and a 3rd for PhysX in XP. CrossfireX is not supported in XP, however having more than 2 graphics cards is. ATi just doesn't want to support CrossfireX on XP for some strange reasons, probably to much of a hassle to work out the drivers.

XP supports at least 3 graphics cards.

You misunderstood me. Say someone has a 4850 and they are trying to decide to either go crossfire (buying a card of equal price as the one they have) or save some money and get a cheap nvidia card. Would they see better performance with the cheaper nvidia card, or with the equally priced 4850?

Some people are on a budget and can't "just buy a 200 series card" lol.

It is better just to buy a quad core CPU and to use it's additional 2 cores for physics in games. In this way you will have more balanced PC.
