Nvidia: Hybrid PhysX Is Technically Impossible
 
Posted by Regeneration on May 5th, 2010, 12:54 PM

Nvidia Corporation has published the following on its PhysX FAQ: "Can I use an NVIDIA GPU as a PhysX processor and a non-NVIDIA GPU for regular display graphics? No. There are multiple technical connections between PhysX processing and graphics that require tight collaboration between the two technologies. To deliver a good experience for users, NVIDIA PhysX technology has been fully verified and enabled using only NVIDIA GPUs for graphics."

It was added in oct 2009 or so, as far as I remember, when hybrids were officially blocked

Bull freaking shit.

I can't believe they have posted that BS on their FAQ. Same BS they tried to feed me last year. If that were the case as I pointed out to them the Ageia PhysX card should have never worked. The only difference is the PhysX software runs on top of CUDA in order to run the calculations on a GPU instead of a PPU.

Then explain how come people do this ALREADY with modified drivers...

And you used to be allowed to do it earlier without driver modification - before nVidia added a "oh chit it's ATI, disable PhysX" feature to their drivers.

This is BS. Comsumers should come first, it should be law!

Welp, that confirms it 100% for me. I am never going to purchase Nvidia ever again. If they don't want to play nice and flat out lie to their customers then I won't support them in the slightest. ATI4LIFE

bullshit lol

nShitia is sick

Looks like another step in the down fall of Nvidia. Intel has already put a stop to their motherboards. Add to that the poor performance of Fermi per watt. Didn't see this coming, as of a few years ago they where on top now they are cliff diving to the bottom. Maybe 3DFX is a death touch.

consumers have never come first to nvidia, they have shown that time and time again, I cant understand why all these diehard fanboys stick with them, they must really like it in the butt

Yep, yet they get screwed from miles away. I wonder when Nvidia will stop all the no sense, lying, and thier dick moves ???

Oh gosh... nVidia please! stop acting like a DickHead, if nMorons die then ATi will become like them, it will be monopoly... so please stop acting like a FAG, you make quality products, its your attitude that is killing nMorons.

I really wish another comapny entered the performance gpu market, if only via had some spunk but they seem content making low powered junk

I don't think the topic is accurate - the FAQ response deliberately dodges the question of "technically possible".

"No", you can't, because they disabled it in their drivers to give you "the best experience".

By making it sound incredibly complex ("multiple technical connections") they just hope you'll make the assumption that it's not possible.

Correction: It's technically impossible to give up the millions of dollars they make with planned obsolescence!

I am sorry but the FAQ is 100% clear on this.

""""Can I use an NVIDIA GPU as a PhysX processor and a non-NVIDIA GPU for regular display graphics? No."""

No. Not, you can't legally, not, we don't advise it.

A clear and concise "No.", which is quite literally a not possible, then they expand it to say for technical reasons, which again certifies it as technically impossible.

No Nvidia fanboys in this thread? I'll give it a go...

You guys are just a bunch of pathetic ATI bitches, Nvidia made it and they can do whatever they want with physx. It's THEIR technology and if ATI got the chance they would act ten times worse. Also, Fermi is going to kick fanboy ATI ass in ten years of more and then we'll see who will be laughing bwhahahahahhaha

If you're being sarcastic then ok, but just in case you are not -
1. It is NOT NV technology, they simply bought it and made it performing worse on CPU's
2. ATi wouldn't act ten times worse - some examples - Open physics initiative, no lockout in 'ATi branded' games (DIRT, Stalker etc.) I don't remember ATi locking anything out.
3. Fermi ? Hope you are still asleep & dreaming - just look at the performance per Watt, and Performance per dollar, then compare it with the performance, price and power usage of HD5890 series.

U R stupid, teh Nvidia rulez.

Yep, and to power 'NV Teh' you would need one of those

nVidiot 3 steps to make your computer GAY

1: Buy any nVidiot card cappable of running poofX

2: Install into your computer

3: Play an nVidiot the way its meant to be GAY game with PoofX turned on

Congratulations you've successfully made your computer GAY

The most accurate commentary I've read.

I mean, they own 60% of the gaming market, why the fuck they have to do this stupid nonsense things!?!?

Not to mention the CUDA effects in JC2, wich if you had two nVIDIA cards only work in the render one, so they fuck themselves up too.

Technically impossible huh? Guess someone forgot to tell MSI and their Big Bang Fuzion board.

It is technically impossible for those not familiar with the PC. Ooooooooooooooooooooooohohohoho \(^o^)/

Hybrid PhysX is of course possible. Nvidia putting customer first....Now that is impossible!
Quote
Technically impossible? What do we have to expect next from Nvidia? AMD Cpu detected, so you can't use a Nvidia GPU.
I hope the nvidia technicians and engineers are bright enough to leave the company.
Does the marketing staff from nvidia know that a pc is modular? You can put in what you want and use it. Well maybe Intel gets really pissed by nvidia some day so they block Nvidia gpus.

Yeah Intel kinda owns them so that isnt gonna happen... but haha yeah i can just imagine during post: Nvidia GPU incompatible with AMD CPU. Nvidia GPU will self destruct in 5...

No, you idiot. Fluidmark has already proved this rumour to be baseless.

Yeah, I know I'm on an old thread. I just ran across and wanted to add my two cents since most posts in this thread are by people that seem to have a problem with reading comprehension.

They did not say it's not technically possible. They said it is not possible because it "has been fully verified and enabled using only NVIDIA GPUs". Meaning, in their own drivers they only verify and enable it with their own GPUs.

While leaving the option there would have been better for advanced users, I don't blame them for not wanting to deal with the costs of supporting this in chips that are in direct competition. It's not cheap. If they leave the option in, then they have to support it to some degree even if it has a disclaimer, and ultimately that cost would be passed to us anyway. If you're that advanced of a user then get the hacked unsupported drivers and stop complaining and use the time for something more productive like working on your reading comprehension.

For the record, I'm not a fan boy of anything. I bought ATI exclusively for about fourteen years to support healthy competition. ATI drivers have always had major issues, but I dealt with it. This last purchase I went with a 3rd party using a NV chip to save some money since NV drivers have always been strong.

first they (nVidiot) buy 3DFX to gain SLI
then they (nVidiot) buy out Agia to gain PhysX
then they (nVidiot) Pay off game makers to cripple games when running on ATI GPU's
maybe next they'll (nVidiot) will buy Lucidlogix for the Fusion tech but will cripple it to void the use of mixed ATI/nVidiot systems

have they actually come up with any game breaking technology themselves or did they just buy shit and cobble it together


what's next nVidot for president why not they already lie to the public what more do you need to do

No, both techniques are entirely different and 3DFX SLI does not duplicate vram contents, it increases the max vram available. The way it renders a scene is also very different

3DFX was going bankrupt and nvidia took the opportunity to buy out and aquire the personel from 3DFX rather then let them all go out of work, This also included certain technologies, but none of the 3DFX api was replicated by nvidia.

Quote:

PhysX was also on the verge of going broke, because nobody gave a shit about accelerated physics at the time, the technology would've been lost completely had nvidia not taken the api on board and remodelled it to work on a programmable gpu rather than an expensive, yet high latency seperate pci device.

Quote:

You have no evidence of this, Infact the choices studio's make on how they implement effects changes the performance of an application per hardware vendor, more so than hardware specific optimisations, and AMD, sad to say, is just bad at certain format swapped textures. If you are STILL referring to the HawX 2 performance, then again, this is an oversight on AMD's part, their tesselators do not work on par with Nvidia's, and there is numerous benchmarks to showcase this, though your posting history already states you will blatantly ignore this the case through an ignorant and biased supporting of Radeon.

You coin me as a rabid fanboy when yourselves are more ignorantly fanboyish than myself, Atleast i go and verify the issues i have had with AMD parts in the past with new parts before bitching out them.

True, nobody STILL gives a shit about accelerated physics.

Well, I don't see that changing until they increase bang for buck ratio. And when taking into consideration the current flow of events (i.e. devs not taking many chances with anything new) I don't see how they could make it usable in the near future.
Quote
the biggest change in the GFX world will be when microsoft standardises Ray tracing.
Quote
The only thing needed would be a GPU that can render it real time
Quote
@ squall I never called you a fanboi infact I've owned both NV and ATI gpus throughout the years that I've been building PC's bang for buck is what concerns me and when an gpu manufacturer pay devs to make games more playable on their hardware it unfairly disadvantages the other guys hardware whether intentional or not. the only thing an GPU manufacturer should be doing for devs is supplying hardware for testing
Quote
and sometimes to give the best game possible, you do so at the expense of certain hardware not being up for it.
