NVIDIA Removes Restriction on ATI GPUs with NVIDIA GPUs Processing PhysX
NVIDIA has reportedly removed the driver-level code which restricts users from having an NVIDIA GeForce GPU process PhysX with an ATI Radeon GPU in the lead, processing graphics. Version 257.15 Beta of the GeForce drivers brought about this change. Possible commercial interests may have played NVIDIA's previous decision to prevent the use of GeForce GPUs to process PhysX with ATI Radeon GPUs, where users could buy an inexpensive GeForce GPU to go with a high-end DirectX 11 compliant Radeon GPU, thereby reducing NVIDIA's margins, though officially NVIDIA maintained that the restriction was in place to ensure Quality Assurance. The present move also seems to have commercial interests in mind, as NVIDIA could clear inventories of GeForce GPUs at least to users of ATI Radeon GPUs. NVIDIA replenished its high-end offering recently with the DirectX 11 compliant GeForce 400 series GPUs.
Update (28/05): A fresh report by Anandtech says that the ability to use GeForce for PhysX in systems with graphics led by Radeon GPUs with the 257.15 beta driver is just a bug and not a feature. It means that this ability is one-off for this particular version of the driver, and future drivers may not feature it.

It's not talking about game support or anything like that.
Has anyone ACTUALLY got Vista to run with ATI and Nvidia drivers at the same time?
OR
Nvidia operates like any other business and profit is their only concern. AMD, Intel, and Nvidia all answer to stock holders. AMD is not the Messiah, and Nvidia is not run by Satan.
to me its a waste of say £20-£40
but nice gesture if you have one lying around
And the shellshocker would work perfectly, as it is the shader power that matters, the memory bus is relatively unimportant for PhysX performance, which is why cards like the GT240/GT220 make great PhysX cards.PhysX and Havok, in a non hardware accelerated environemnt offer pretty much the same effects for the same performance hit, everything is run on the CPU. So really, there is no reason to say "Havok FTW", as it offers nothing over PhysX, but PhysX offers the option of hardware accleration to add more effect. Yes, more effects on the screen means more to render for the GPU, and if you have a single GPU doing PhysX also, then the performance hit can be rather noticeable. However, if you don't like it, just turn hardware accelerated PhysX off, and the game won't be any different from a Havok implementation.
