Hybrid PhysX Support Will be Disabled in WHQL R256 Drivers



NVIDIA PhysX



Bad news… Yesterday was a great day for Hybrid PhysX (Radeon for 3D and GeForce for PhysX) thanks to the nice gift in R257.15 drivers. But the support of Hybrid systems will be disabled in the next WHQL R256 series drivers.

Here is the official position of NVIDIA:

A lot of you have been asking about PhysX and the 257.15 beta driver we posted on Monday. First off it is true that PhysX is enabled when running on NVIDIA GPUs when AMD GPUs are used in the same system. PhysX is a compelling technology that makes PC games great – I am not surprised our fans are eager for it. When using this beta driver no additional hacks are required to enable PhysX. While it was not intentional, due to the overwhelming positive response to the beta driver we have decided to leave the beta up with support enabled.

The fact remains that the investment to do a full QA cycle on this AMD/NVIDIA hybrid GPU configuration is beyond what NVIDIA can support at this time. The cost of maintaining AMD/NVIDIA hybrid configurations is larger than the development expense for PhysX, and I do expect that there are games and configurations where this type of system just won’t work. Please, don’t call me :>. Therefore our WHQL certified drivers will continue to have this support disabled.

:(

    So the cards that Nvidia could potentially sell, to ATI+ Nvidia physx configuration lovers, are not even enough, to cover the development cost. That really says much…!

    i bet if nvidia didn’t buy physx they would have time to support hybrids but im not gonna complain because i don’t work for nvidia/ATI

    “and I do expect that there are games and configurations where this type of system just won’t work”

    I havent seen an issue yet where a hybrid system “just wont work”…

    only when Nvidia start screwing with the drivers do things stop working…

    geeze..i have proof that a 9400GT will run physx perfectly fine, albeit slow…

    i dont know why they dont just leave the drives alone and just say they dont officially support hybrid setups… im use the userbase will contribute to its own support system

    theres gotta be a case for anti-compeditive behaviour here..

    a cool solution (in the first time) would be to enable hybrid physx in all beta drivers only and disable it on WHQL…

    They never supported this, but is still works…

    But like AMD where you could unlock CPUs, some people were complaining to AMD that they bought their CPU and couldn’t unlock it…
    If nvidia allows this, there would be people complaining, that it doesn’t work for them.

    Hopefully more beta drivers like this!!

    Two words nVidiot F_ _ _ You!!!! you really know how to alienate the gaming community, real nice and here i was going to buy an nVidiot card to go with the my ATI seems now with the bitch attatude that nVidiot have I’ll not be going near them bring on the ATI OpenCL Physics!!!
