Nvidia does it for a reason and a good one at that, I may hate nvidia but im not going to slate them for it, and it's for the simple reason people are whiney bitches.
If nvidia leaves such a feature in their drivers then the only thing that's going to happen is somewhere down the line the driver is going to have an issue or bug with an ATI driver and everyone is going to boohoo at nvidia for it. Granted physx should just be opened up for everyone to use but obviously they won't do that for exclusivity rights but still, it'd just cause more problems on nvidia's plate that they shouldn't have to deal with down the line. If it was a compat issue with a certain ATI card, everyone would expect nvidia to fix it.

um
the way i understood it, it still doesn't run on ati hardware..
it just won't artificially TURN OFF when ati is detected
so the only way ati would have any negative impact on physx at all would be if it actually broke the nvidia driver, or spoofed it was nvidia, which would allow physx to run anyway
it's just anti-competitive bullshit and there's no excuses for it
hooray for the corporations.. fuck the consumer

You're wrong Spykez, at least for Windows 7 systems. Under Windows 7 you can have multiple drivers running side by side without a problem, and those that were using the hack to get these 2 to run never had any issues. Same thing goes for Lucid's Hydra technology, ATI and NVIDIA can work just fine. Under XP it´ll give problems, but that´s a separate driver anyway.
It still doesn't make sense to me though, NVIDIA is actually losing money on this. A 5870 + GTS 250 is as expensive as a GTX 295 was or 480 is, and delivers the same performance WITH PhysX support. I would've traded in my 9800GTX for a GTS 250 if it wasn't for this cockblock maneuver (9800 doesn't fit in my case, GTS 250 would because it's a much smaller PCB+cooler) 
There's been some tests proving that a G80/G92 is the ideal price/performance point for PhysX and CUDA.
Still, I'd rather see NVIDIA getting off their proprietary horse and join ATI, Bullet, Havok and whoever else is working together on an open GPGPU physics platform now. Same goes for CUDA vs. OpenCL

Your missing my point. It has nothing to do with windows 7 but rather bugs in a game the nvidia might have to fix their own driver for, adding this fix in a driver for their own video card has the possibility to "break" something when using an ATI card, maybe a game crash, maybe a glitch here and there, and like i said before, nVidia would get the flak for not fixing an issue with an ATI card.

what has that to do with physx?
two devices with the same purpose and different drivers are hazardous to begin with
there might be conflicts with game rendering here and there
but that's graphics
physx is a physics middleware that hardware accelerates by a proprietary interface exclusively through an nvidia card
even if the machine has a billion cards attached, the physx code would still find an nvidia card to interface with

This.
The D3D and PhysX layers are completely separate, and driver wise it can co-exist next to ATI just fine. If they really blocked it for the reasons they claim, then they wouldn't allow any driver to install in the first place if there's an ATI card in the system, both graphics and PhysX. If a game encounters a PhysX bug, they have to fix it regardless of ATI being present or not, because that bug will be present on NVIDIA cards as well.
