Hybrid PhysX Support Will be Disabled in WHQL R256 Drivers
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.
