ATI Radeon HD 5870 & 5970 with NVIDIA PhysX

QUOTE: "If you haven’t heard already, the 257.15 Beta ForceWare driver set from NVIDIA accidently had the ability for ATI users to again use an NVIDIA card as a second to do PhysX. The whole ordeal created a bit of drama around the web; as soon as it was discovered by NVIDIA they yanked the driver and put another one up that disabled the ability.
After a bit of uproar, they put it back up but said that it wouldn’t be included in future drivers; they kind of dribbled on about how it’s expensive to maintain it for ATI cards. It sounds like a load of crap to be honest, because it’s been disabled for ages. We’re sure in the last few months they’ve done nothing and all of a sudden it was slipped in and working fine on ATI cards. I don’t know what NVIDIA have against making money, but the whole thing sounds stupid."
