NVIDIA Removes Restriction on ATI GPUs with NVIDIA GPUs Processing PhysX

NVIDIA has reportedly removed the driver-level code which restricts users from having an NVIDIA GeForce GPU process PhysX with an ATI Radeon GPU in the lead, processing graphics. Version 257.15 Beta of the GeForce drivers brought about this change. Possible commercial interests may have played NVIDIA's previous decision to prevent the use of GeForce GPUs to process PhysX with ATI Radeon GPUs, where users could buy an inexpensive GeForce GPU to go with a high-end DirectX 11 compliant Radeon GPU, thereby reducing NVIDIA's margins, though officially NVIDIA maintained that the restriction was in place to ensure Quality Assurance. The present move also seems to have commercial interests in mind, as NVIDIA could clear inventories of GeForce GPUs at least to users of ATI Radeon GPUs. NVIDIA replenished its high-end offering recently with the DirectX 11 compliant GeForce 400 series GPUs.

Update (28/05): A fresh report by Anandtech says that the ability to use GeForce for PhysX in systems with graphics led by Radeon GPUs with the 257.15 beta driver is just a bug and not a feature. It means that this ability is one-off for this particular version of the driver, and future drivers may not feature it.

wahdangunhmmm so if QA nvdia so great why they release WHQL driver that shut off the fan and make the card overheating.

it seems to me they don't take QA seriously
There is no point. Hes blinded by PR rhetoric.

Yeah, that is definitely proof that nVidia doesn't care at all about QA.:rolleyes:

Or maybe it is a sign that they are already working with a QA department that is stretched thin enough to let the occasional thing slip through. So adding more QA work load is probably a bad idea...

But yeah, the nVidia doesn't care about QA theory makes far more sense.:rolleyes:

Guys, just to let you know, i've made a fix for Batman to make the game use its native MSAA code about a month ago. You can find it on NGOHQ.

As for
doesn't work on ATi hardware as it wasn't coded for ATi hardware
, you are wrong if you think so. It's all about 2 VendorID checks - one in the launcher, another one in the game.

It doesn't work, there was a long thread about it and the people that tested it were able to enable the option in the options, but it didn't actually do anything. No AA was applied, and I seem to remember it actually caused the game to crash sometimes.

Edit: This specific post talks about the issues with forcing the vender ID, which shouldn't be any different then removing the vender ID checks. Basically, AA doesn't get enabled, or at least not the way it should, with some things having some AA applied, but others none at all. It just doesn't work right on ATi hardware. AFAIK, no one has got it working properly. You can enable the option in the settings, but it doesn't actually work properly.

In fact that's the point. That driver didn't shut off the fan in every card, not at all, only on a very few number of ones and look what has happened. Yet, you can bet that someone got punished in the QA department anyway.

Besides I never said they are great or serious about QA, not at all. I said they don't want to spend money on QAing something that would not make them more money than it costs. It's that simple and at this point I don't care if you all understand that simple concept or not.

driver66For all of the bitching about how physx sucks and is "useless" These threads sure do generate A LOT of interest
This thread comments section is extense by now. I think driver66 is right, we, ATi owners, are making a big deal of this stuff and giving to Nvidia arguments about PhysX and CUDA. I wouldn't be surprised that Nvidia's marketing department starts using some ATi users' comments to advertise something like "PhysX and CUDA makes them envy you".

If you really want to try hybrid PhysX out, use the beta driver or hack and play ;)

And they would be wrong about this. It's not about envy, it's about limitations they are creating to advertise their products. People just don't like these limitations. You know, a twice-dropped fps after breaking a glass in-game or inability to use in-game MSAA look more like limitations to me.
People are still using nvidia GPUs to process PhysX, this is 100% legitimate since nvidia said their GPUs can process PhysX, don't you think? Why say they do envy if they are just using a product they own for a proper task it's supposed to process?
wahdangunbtw, why this "fix" was detected as virus with my avira?
Because your avira doesn't know how to deal with some packers, i suppose.
Didn't you know that the Hybrid PhysX mod is also virus-tagged because of antivirus mistakes?..

Sorry, that was the link to the original discussion when the Batman AA thing was big in the news. They didn't remove the vender ID checks, they just emulated the vender ID. The result was the same though, it allowed MSAA to be enabled in Batman, and it didn't work properly. It sort of worked, but not totally.

Actually, if you believe Regeneration from NGOHQ, it is a big conspiricy by nVidia...because nVidia has so much power they can get anti-virus makers to put false positives in their software...:rolleyes:

newtekie1It sort of worked, but not totally.
I don't quite understand this... For me it worked perfectly (fix, not emulation), i mean the game was using its own MSAA without any problems. If by "not totally" someone means that this native MSAA is not perfectly nice, that's because it's not a regular AA scheme, but a custom-implemented one at the engine level with some limitations. This doesn't change the fact that such MSAA looks same for nvidia and ati GPUs, though.
My screenshots of this MSAA can be found at the NGOHQ topic.

Nope, perhaps some people who screamed about this were somehow biased, but the whole false-positive thing was caused by the packer and bad antivirus logic only.

You know, it's just a trivial thing today. I remember the very first time i was browsing through official Batman AA forums' content section, where users put their custom skins for download, some helpful tool they were using was flagged as a virus too. Why don't they scream about it? Because they understand it's not a big deal when some AV software does a mistake.

You mistunderstand me. I totally agree that it is a false positive. However, the last time something came from NGOHQ that was a false postive, several sites picked it up and reported that it contained a virus according to several anti-virus programs. Yes, that is what tech sites do. One site posts a popular hack contains a virus, and the rest report the same. Regeneration completely flew off the handle, and started going on rants about how it is a scam that nVidia bribed all those sites to report it as a trojan...

These sites included far better sites then his, including HardOCP and Guru3d. He even claims both sites are corrupt, in fact he claimed every site the reported the news was part of the scam and corrupt.

Of course he also blames eVGA, and by extension nVidia, because there was discussion about it on their forums by users with no affiliation with eVGA or nVidia...

I'm sure he now that your hack has been reported as a virus her, he will likely do the same and claim TPU is in nVidia's pocket and it is a big scam.

Of course if a more legit packing was used for these mods, and not one generally used by viruses to avoid detection, this wouldn't have been a problem to begin with...

his mod shows clean in kaspersky. its not the mod-makers faults that some people insist on using shitty heuristics based AV's.

It doesn't matter, that isn't the point, false positives happen with every AV.

The point is both mods are packed in a way that is known to cause false positives. The mod makers know this, yet they continue to do it. There is no reason they can't pack their files in a way that isn't known to cause false positives. It certainly is the mod-maker's fault that they use shitty non-standard packers.

And the main point is that when the false positives happened, and were reported, Regeneration went ape shit calling every site that reported the news corrupt and part of a scam against HGOHQ.

I want to see more comparison screen shots with and without in game AA, on both brands of cards at the same settings.
