Nvidia Disables PhysX in Presence of ATI GPU

Nvidia and ATI – longtime rivals who do not play nice together. Although having both ATI and Nvidia hardware inside a PC is unlikely, there's now clear evidence trouble happens when you put the two together.

Those with the very rare configuration of having an ATI GPU for rendering graphics and a Nvidia chip for processing hardware PhysX will find themselves unable to compute.

Anyone running Nvidia driver version 186 will find PhysX acceleration disabled when ATI hardware is also present in the system, SlashGear reported.

Nvidia customer service responded to a user regarding the issue, saying, "Nvidia supports GPU accelerated Physx on NVIDIA GPUs while using NVIDIA GPUs for graphics. NVIDIA performs extensive Engineering, Development, and QA work that makes Physx a great experience for customers."

The email continued to list a couple of reasons why the Nvidia GPU would refuse to accelerate PhysX, with one of them being, of course, for business.

"For a variety of reasons – some development expense some quality assurance and some business reasons NVIDIA will not support GPU accelerated Physx with NVIDIA GPUs while GPU rendering is happening on non- NVIDIA GPUs," it read. "I’m sorry for any inconvenience caused but I hope you can understand."

It's a rare setup and a rare problem – probably affecting only the most hardcore – and it's unfortunate that it's no longer an option for those wanting the best of both worlds.

    Is anyone surprised in this day and age of anti-competitive practices? It would hardly be fitting to let anyone know that your tech works better with a competitors product. I doubt it would, but if it did, that would be the height of industry embarrassment.

    What a shame. Can't say I'm surprised though, this is the way NVidia has been getting recently.

    I have a nVidia card (GeForce GTS 250) on an AMD chipset (AMD 770). Am I in trouble?

    Way to go Nvidia, shoot your customers in the foot, obviously they bought an Nvidia product to accelerate PhysX. I currently run an Nvidia card, but I think my next GPU will be ATI, I am getting sick of Nvidia's child like antics.

    AMD would do the exact same thing. Big damn deal.

    I guess some lawyer will get rich by filing class-action lawsuit against Nvidia for falls advertisement. They advertised and sold their cards with PhysX and now they don't hold to the their side of the bargain.

    And the second thought, This move could be the doom for PhysX. Just like beta-max failed because the "brilliant" decision by Sony to maximize their profits from licensing fees.

    Who cares? How many users care about Physics, 0.0001%?

    Nvidia has no DX11 hardware to date.

    No, this only regards those with ATi AND nVidia GPU's in the same machine. The chipset is something completely different so have no fear.
