I never got a proper answer when I asked in anandtech, maybe someone here knows, maybe kyle will be willing to test it for us...

Basically the gist of it is:
Nvidia has driver level DRM which:
1. Disables physX if an ATI GPU is detected, even an ATI IGP
2. Disables SLI if the bios does not contain encrypted keys that prove the mobo maker paid nvidia 5$ for the privilege of supporting SLI.
They have actually been working quite hard to close the holes in the DRM, as cracked drivers were made to bypass it.
Then nvidia released beta driver 257 http://www.anandtech.com/show/3744/...terogeneous-gpu-physx-its-a-bug-not-a-feature
which did not contain the DRM preventing physX on machines with ATI chips. nvidia explained that it was a mistake and they will replace the download with a DRMed one ASAP. Then they went back on it and stated that "due to overwhelming support they decided to leave the beta driver with those options enabled" (and a BS explanation how they DRM it to ensure quality...). However, there has been confusion on whether or not they mean that only that specific beta driver would remain DRM free, or that from now on all beta drivers will be DRM free.
Well, there have been several releases since, so what is the current situation? can you use physX if there is an ATI GPU in your system? it should be fairly easy to test if you have a forbidden setup.
Can someone please confirm if the current beta drivers have the DRM or not? I am dying to know which way nVidia went.
Also, it would be nice to know if those specific drivers only lacked the hetrogenous computing DRM, or if they also fail to test for SLI mobo bios keys
