PhysX Runs On RV670, Scores 22,000 CPU Marks in 3DMark Vantage
Eran Badit of NGOHQ.com successfully modified NVIDIA CUDA (Compute Unified Device Architecture) to operate on an ATI GPU and has been able to run the NVIDIA PhysX layer on an RV670, the Radeon HD 3850.
He tells that enabling PhysX support on Radeon cards is not particularly difficult, leading us to believe that physics on graphics cards may not so much be a technology problem but an issue of corporate dynamics.
On his first run, Eran got a 22,606 CPU score in 3D Mark Vantage, enhancing the overall score to P4262. A comparable system without PhysX-support will cross the finish line at about P3800.

As for the legality of this mod, I doubt it is legal, and I'm sure nVidia will put a stop to it, which sucks. I know it sucks that ATi would need to pay nVidia fees to use the technology, but it is only fair. NVidia put out a huge chunk of change to buy Ageia, why should ATi get the benefit of that for free? ATi should just buy the rights to use PhysX and be done with it.
It seems like he reverse engineered it?

It's legal than...
The fact that it can be used on ATI cards or any others is a feather in their cap, not a detriment.
If they allow it, the open source community will hail them as heroes of the cause.
Thats all I have to say.
Just my 2 cents ;)
Can't wait for my 4850 crossfire setup + radeon physX LMFAO
Just think what an RPG would be like if you could blow a dam and flood a town that was downstream. Or the inverse, you build a dam and create a lake upstream.
The possibilities are endless.
At the moment it is just being used for a little eye candy, but that will change.
when i want to play GRAW or UT3 i must install agea drivers, ewen if i don`t have agea physx.....so if drivers are installed and CUDA open source supported, we can play PhysX legal :)
Unfortunately, this sounds more like a case of modified drivers.
i can score 32k on the cpu with this new driver for my g92 and a 4ghz duo

Besides, I can't forsee ATI being willing to pay for, nor support, CUDA or PhsyX at the moment, considering how closely AMD have been working with Havok recently (for a reference: forums.techpowerup.com/showthread.php?t=62755&highlight=havok), and I'm sure a joint collaboration with ATI and Havok is not too much further off, either. The red camp knows they've got their hand in the candy dish being able to work with Havok, they're not going to fudge that up.
