For NVIDIA's PhysX technology, it has been a roller-coaster ride since NVIDIA's acquisition of the technology, and its makers. As much as PhysX quickly became one of the important selling-points of NVIDIA's consumer graphics line GeForce, it also had its small share of controversy, linked to market dynamics more than anything. With the technology's port to the GeForce GPU, enthusiasts fancied having the freedom of choice with a primary GPU that is dedicated to rendering 3D graphics, and a second GPU that is just about powerful to assign as a dedicated PhysX GPU.

Does it still require having two monitors or dual video inputs on your monitor to setup?

Well, Nvidia's somewat being "selfish" by restricting the ability of using their lower end card with other GPUs, but I guess it makes some kind of sense. They're afraid of losing against ATI, especially with the release of the 5800 series. Thank god for modders out there to come to the rescue :rockout:

This won't really be an issue for me, assuming Fermi (GT300) will defeat 5800 ATI. In that case, I will stick with Nvidia. If Nv fails to impress me, n the rest of the world, then ATI it shall be, n I extend my thanks to those awesome modders out there. :toast:

It all leads back to ATi's flat out unwillingness to support PhysX running natively on their hardware. If they had just put forth a little effort back when nVidia was extending the olive branch, PhysX would be running on ATi hardware without the need for a secondary nVidia GPU at all, and we wouldn't be in this situation.

Wasn't ATI working with Havok until Intel purchased Havok? Yes they were.

However, ATi is still working with HAVOK on it all... right now, both companies hate Nvidia, so working together to oust them from the market will be beneficial...

The downside is- once Nvidia caves in... it will just be Intel vs ATi in the GPU market.

If that wasn't bizarre enough, with the latest drivers, you can't even pair an Ageia PhysX PPU card with an ATI Radeon GPU going about its business...
That can't be legal...

Can they do that???

So if I enable the onboard 8200 vga and install NV drivers + this patch, I can use it for PhysX along with my 4850 GPU in W7?

Well, maybe if Nvidia would opensource PhysX, they would. "Olive branch" my ass.

As is, it's a proprietary standard. There's no incentive for any hardware company to use PhysX, if it's always going to be under Nvidia's control. Even if ATI did license it, Nvidia would probably ensure it only worked best on *their* hardware -- what would be the point?

And licensing issues have nothing to do with Nvidia's dick move of not allowing PhysX to work on a secondary Nvidia card if you were running a main ATI card.

That's just greed, coupled with a fair amount of butthurt. :laugh:

That can't be legal...

Can they do that???
They certainly can -- PhysX is Nvidia's own proprietary standard. All the more reason for no one to use it.

nVidia's excuse may be that they can't guarantee everything will run properly with a different vendor's card doing the primary rendering, but that doesn't constitute disabling the adapter. It constitutes simple not offering support for those setups.

It has happened. Those ASUS/BFG Ageia PhysX cards won't work (with recent drivers), if the drivers see an ATI GPU. As for legality, NVIDIA can do what it wants with its hardware/software.

NVidia are such fuckers for adding these restrictions, unfortunately they own PhysX so they are allowed to put whatever restrictions they want...

No one's hacking it "for ATI cards" -- they're hacking it so that it can work with the Nvidia cards they already bought, but just use as secondary physics processors.

Get it? This kind of shit is the kind of reason why ATI has never bothered to use PhysX.

Doesn't nvidia see that these antics only make OpenCL more attractive?

And I imagine that's the same reason ATI would turn down PhysX, and it looks like the right decision. As somebody pointed out in another thread, Nvidia aren't giving themselves the best image as far as being able to govern and control a standard is going.

This thread will be some NV users battling to the end for their green goblin juice, ATI users laughing about the clever way a driver can be minpulated to defeat the joke the lock out was anyway. The people who don't know or care and don't use it will shrug and either get pissed at NV for the crap they pull, or just leave the thread.



So, someone is in the lead already with defending NV, others are following up with the "why ATI sucks" arguments, red users are already laughing and some are preparing for another heated battle of red VS green.

I'd be curious what invida charges for licensing cuda/physx. Probably a ton, it's bad enough that they license havok...Had this situation gone well in the beginning, both Ageia and Havok would have remained independent and licensed to either GPU company. With the invidia logo on the hardware...I'm sure it's an arm and a leg, Havok is no better probably, but it's better established than Physx.

I don't think they're working to oust them. Oust PhysX - yes, NV - no, as OpenCL is aimed to run on all capable hardware...

I don't give a damn why they're doing it. :laugh: Probably 3D Mark Vantage E-penii scores like bta said.

But the fact that Nvidia, in a classic dick move, has stripped away functionality from products that people have already bought should make anyone angry, no matter what side of the ATI/Nvidia divide you sit on.

Seriously, if it's not, it's really really hard not to look like just an apologist.
