When asked for the reason behind the change, an NVIDIA representative stated: '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.' From a certain perspective, this definitely makes sense. That's what's happened over at NGOHQ, where forum reader DarthCyclonis discovered that NVIDIA drivers released after the v185.85 WHQL package (i.e, 186.18 and higher) removed the ability to use a GeForce 8xxx, 9xxx, or 2xx card as a dedicated PhysX processor if an non-NVIDIA GPU is present.
Every so often, someone on the 'Net stumbles across something noteworthy, but the news doesn't spread until weeks or maybe even months later.
