| Nvidia Driver Bug Removes Hybrid PhysX Blockage (Updated) | |
Windows 7 allows two display drivers to be used at once - like in Windows XP. Therefore, it is possible to use an Nvidia card for PhysX and ATI card for graphics rendering. As you already know, Nvidia has robbed its customers by disabling the PhysX technology (GPU and PPU) anytime a Non-Nvidia GPU is present in the system (even IGPs) since the release of 186 GeForce drivers, to prevent consumers from using hybrid PhysX. As predicted, the community responded critically and eventually a user by name of GenL created a patch that removes the blockage and reclaims the feature. The following is Nvidia's explanation behind their actions:
"Physx is an open software standard any company can freely develop hardware or software that supports it. Nvidia supports GPU accelerated Physx on NVIDIA GPUs while using NVIDIA GPUs for graphics. NVIDIA performs extensive Engineering, Development, and QA work that makes Physx a great experience for customers. 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. I'm sorry for any inconvenience caused but I hope you can understand."
But now it seems that Nvidia has removed the hybrid PhysX blockage in the recent 257.15 GeForce drivers. However, it is still a mystery for us if it was done intentionally or perheps it is just a bug. "I'm seriously amazed. I've tested it by myself on Windows XP and Windows 7 x64 - it really works out of the box with 257.15. And even more surprising - timebomb issue is gone too. It would be at least one respectable deed by Nvidia, and my mod would be obsolete, which is great for everyone. So we better hope this is permanent." said GenL. Update #1: This is a bug! confirmed by Nvidia. "Yes, this is a bug in the latest build of PhysX that was packaged with the driver. We'll be fixing this issue ASAP - the WHQL driver launching in early June won't have this issue." Update #2: Nvidia's Tom Petersen has commented on our article through the nTersect blog: "A lot of you have been asking about PhysX and the 257.15 beta driver we posted on Monday. First off it is true that PhysX is enabled when running on NVIDIA GPUs when AMD GPUs are used in the same system. PhysX is a compelling technology that makes PC games great – I am not surprised our fans are eager for it. When using this beta driver no additional hacks are required to enable PhysX. While it was not intentional, due to the overwhelming positive response to the beta driver we have decided to leave the beta up with support enabled.
The fact remains that the investment to do a full QA cycle on this AMD/NVIDIA hybrid GPU configuration is beyond what NVIDIA can support at this time. The cost of maintaining AMD/NVIDIA hybrid configurations is larger than the development expense for PhysX, and I do expect that there are games and configurations where this type of system just won’t work. Please, don’t call me :>. Therefore our WHQL certified drivers will continue to have this support disabled."

| | | | 39 Comments | | | did CUDA is an exception ? | | | | | | If it is indeed intentional action then perhaps it won't be as bad to physx as we thought.
Nv will sell some of their midrange cards just for CUDA and PhysX while ATI fans and those interested in AMD products will have opportunity to own 'best of both worlds". | | | | Also this beta driver finnaly activated OpenCL on my 8800GT
I actualy think it's a bug on they're side... time will tell
One thing is for sure, that image from the topic will become reality if it proves to be just a bug  | | | | Well we will know soon enough with the next set of official drivers that come out. On the other hand Nvidia partners still have a lot of overhead with 2XX and 9xxx cards based on the G92. With Fermi being a semi flop this move might be away for them to sell off these older generation cards as nothing more then high priced PhysX cards.
Money is always the driving factor. |

Glide only worked on 3dfx, many gamers where left out until "glide wrapper" but still no sli with non 3dx cards and none of the special effects.
I did not cry and complain then so i wont now. I hate what nvidia did but i cont expect them to become socialist. They are out to make as much $ as they can.
Most people would do the same if they had their own business and could smell the profit.
I doubt the big bosses at nvidia or their grand kids will ever need to work! | | | | Quote:

"* Adds a new NVIDIA Control Panel feature for ultimate control over CUDA GPUs, allowing the user to effectively choose which GPU will power each CUDA application."
So i assume it is that... i really hope nVidia change their moronic attitude, its hurting their sales and their reputation, they are indeed loosing customers and market share as mentioned in another topic, so its either change or die.
Again, if it was intentional i would be the first to applaude them... still, wont buy any more nVidia cards since ATi has proven to have a value products at extremely nice prices, maybe if nVidia would do something similar?
PhysX isnt that good of a thing honestly, i havent really see a difference when using my 8800GT for PhysX and when using only the HD5770... so i think PhysX is overhyped and not worth all the excitement, i used to think it was worth it some time ago. | | | | | | Can some post a CLEAR CUT version of these drivers where PhysX works on ATI?
I downloaded the drivers from Nvidia's site about 20-30 minutes ago and PhysX was disabled.
The file size was 123MB. |

| Quote | | | | | I figured if anyone had this rare driver release it would be here. [sigh]. But apparently it is simply unavailable. If anyone has a link to the earlier version of 257.15 please post it. Someone should upload it to pirate bay to keep it out there. Or maybe share it on emule since it is a relatively small file. | | | | It's was just to impossible to be true. | | | | Nvidia allways killing the goog I like to see my voodoo 5 with sli technology and like playing with my old ageia card what tha hell with nvidia remove the support off glide in his time (I never see again the colors that voodoo gives), and now ageia | | | | Thank you Rege for the 'unfixed&bugged' drivers - I'll try to extract just the PhysX from it 
Guys wanting to download the unfixed driver - just click on the link that Rege posted 4 posts above. | | | | Guys, there are NO updated 257.15 drivers ATM. Download them from nvidia site, they are still there and nobody changed them since May 24. PhysX SS package inside is from Feb 22, not changed either.
Don't panic after seeing no PhysX tab in Control Panel... Just try and see for yourself. | | | | As for...

Surely they could just have a disclaimer to enable it for non Nvidia GPU combos, e.g. "we do not accept any responisibility and liability for failure of Physx, hardware dmg, etc. etc. ACCEPT/DECLINE", like they do for custom overclocks etc. No testing required at all.
Also note, Guru3D, who seem to think they should report ANY news that hits ANY site without investigation, I dont think have reported this, nor have they reported the Nvidia blacklist news post, yet they report random false positive virus responses to known wrappers. | | | | Quote:

| Quote | | | | | So can I just install the Physx SS from this package and have Physx support with my ATI card? I do not have an Nvidia card, only ATI - will it work!??? | | | | If they make a practice of this and release a "bugged" driver here and there, that would be nice. Sort of a way to keep the wolf content and all the sheep accounted for. Of course, users being the wolf. | | | | Quote:

*While it was not intentional, due to the overwhelming positive response to the beta driver we have decided to leave the beta up with support enabled.*
Ohh so now they care for their customers? since when? i think nVidia are hipocrites because they know exactly what their customers think of them, you really have to hate nVidia, not their products... only nVidia as a corporation. | | | | The very idea of forcing customers to stay 100% nvidia is not business smart. This isn't about making as much money as possible, it's about their fear and desire to control the market. It shows that their position is weak. It's very short sighted. There's no reason to think that nvidia can't implement a smart business model where they can coexist with ATI or other graphics adapters in PC's.
And no, I don't buy them completely disabling physx in these cases and not even allowing *unsupported* use of physx in dual configurations. That's a domineering control-freak mentality and us nvidia customers are very upset about it. I was an eight year nvidia customer until they pulled this type of stuff with physx and I won't buy their cards because of it. | | | | Doesn't work with my Ageia PPU. | | | | What they mean is that they let this particular beta driver have it. Next driver on it will continue to be blocked. | | | | The next beta driver too or will the next beta driver come again with this "bug".
Btw.: I think it is quite interesting to call a "feature" a bug. I heard the opposite calling a bug a feature but this way around is new | | | | Quote:

the physx package can only be used as an upgrade install ontop of older ageia drivers. | | | | Quote:

Not sure why PPU user even try those new drivers for GPUs... | | | | Anybody tested this on 258.69 drivers yet? | |
