NVIDIA GeForce To Quadro Software Mod 152

Posted by ScuttleMonkey from the you-bought-it-might-as-well-use-the-whole-thing dept.
babyshiori writes "The NVIDIA Quadro family of professional graphics cards are very, very expensive. But many people know that Quadro and GeForce graphics cards are virtually identical in hardware. Obviously, you cannot just use Quadro drivers with your GeForce graphics cards. However, there is an easy way to soft-mod an NVIDIA GeForce desktop graphics card into an NVIDIA Quadro professional graphics card. Tech ARP shows us just how to do it. 'It all revolves around the driver support for professional 3D applications like 3ds Max or Maya. Quadro drivers allow the Quadro to be used to accelerate the rendering operations of such professional 3D applications while GeForce drivers do not. This is the basis for the premium prices NVIDIA (and ATI) charge for their professional-grade graphics cards.'"

    I work in an engineering field where we use Quadro cards for visualization of largish process plants in an AutoCAD 3D environment.

    This type of work is not as intensive as 3D animation.

    Over the years I've seen not much difference between "professional" and "consumer" video cards even though the cost between the two can be $600 or more.

    Even with relatively lame, $200 cards the walkthrus are pretty responsive when using the proper viewing software (the "walkthrus" are typically specially created for responsiveness so we can zoom to detail we need to see).

    Perhaps sluggish performance is a result of demos given by people who intentionally attach one entire GB of 3D models to one session and use that to demonstrate (even though no 3D modeler would ever do such a thing).

      I do the IT for a cad shop, and we've run the range of video cards, settling on these Quadros (the sub $1000 models). I'd be very curious if this mod just gives the cheap card some of the accelerations the real card has, or if it can actually keep up in the real world. Not just running canned demos, but actually plugging away in Autocad all day long...

      A benchmark of a couple of cards would be handy.
      (but for the price of a video card, I suppose I could find out myself)
      • That's the trick - there are so many combinations that a apples-to-apples comparison is impossible (and so expensive), so people go along with whatever the existing trend is.

        I've not seen noticeable differences between a Quadro 256MB card and a generic 128MB card but perhaps my applications are different from other users'.
      • If you do, make sure to return the results to Tech ARP. Or post them in the forums of Guru3D, where the tuning app was made. Other people might be interested, and they did some hard work to create the applications.

        Of course, if you look in the Guru3D forums, the hack isn't new, and I don't know what Tech ARP really did other than write a tiny article around it. Bring it in the spotlight I suppose.

        I'm not sure. This sort of hack is "unsupported", meaning, if you run into any trouble at all, the CAD software maker, the computer maker and the video card maker do not have to help you. I think it's a nifty little hack, but if you depend on the CAD machine, getting the right card in the first place is less expensive than a day's worth of down time for a user + the tech trying to get it to work again.

        The extra cost goes towards developing and maintaining a specific driver set for the very small number of people using a low volume piece of software. The driver will load different pieces, different versions of itself based on what software is running. That's because the software is aggressively tested with specific versions of the driver to work right. That sort of support isn't cheap, and that's what you get when you pay for a Quadro.

        From what it sounds like, the mod doesn't actually change anything, it just modifies the PCI id so the driver thinks the card is Quadro branded instead.

        Like so much else in the 'corporate computing' world, it's merely rebranded generics, with a heftier pricetag. The hardware is usually the same, and probably in this case too. Much easier to use software to artificially prevent cross-market competition; as most corporate purchasers aren't spending money out of their own pocket they don't particularly care that they're getting scammed.

        While there may be only minor technical differences to the cards, the real difference is in the software. In a nutshell when you're buying the "inexpensive" card, you're not paying for the extra costs that NVidia (or ATI) incurs when they must expend resources to provide drivers that support the high-end applications. So unless you want consumers that could care less about the high end features to pay more, and the people that care about these features to pay less, you'll probably be happier with differentiated products in this way.

        Don't forget companies are there to make money, and if they're not able to do this then either the company or product is likely to disappear. Personally I'd rather have NVidia around, if I need the high-end features, I'll figure out how to afford it...

        Because the Quadro's extra features are not beneficial to gaming. I have a Compaq nw9440 with QuadroFX 1500 graphics (256MB, PCIEx16.) The additional features are that you can have the card render to a buffer (GPU-accelerated rendering) and you can use 10 bits per channel (r,g,b) color. Whee! Neither is useful for gaming.

        The additional color depth could be neat, if it's even used when your source textures only have 8 bits per channel. I don't know the answer to that. But let's face it, 24 bit color is probably enough for gaming and frankly, I never minded so much when I had to use 16 bit color back in the day because my computers were weak. this is pretty much the only cutting-edge system I've ever had and it was only cutting-edge for a month :)

        There WAS a SoftQuadro hack for some of the older geforce cards which had corresponding quadros. Quadros were offered with a lot more memory too, which is not something you can fix with a driver... But the mobile quadros certainly don't have more memory, so there's nothing lost there...

      The simple truth is that a lot of the "magic" is in the driver and they want to try to protect this stuff. However, an even simpler truth is that if you release your drivers then the public will help you write them. As intel has stepped into the 3D market with its open source drivers - easy to justify since they're not chasing the #1 spot in quality - the other makers have had to look hard at how their closed source is going to cost them in the long run. Both ATI (AMD) and nVidia have come around to the right idea, and now it's just a question of how long it takes to make their original drivers irrelevant :)

      • Both ATI (AMD) and nVidia have come around to the right idea,
        When did nVidia come around? If there's been any release of technical documentation on their chips, or any promise of it, I've somehow managed to miss the news.

        Having ventured into the creepy world of computer graphics drivers (in embedded land), I've found that there's often another issue at work as well. A lot of graphics vendors (at least, a lot of the smaller ones) cross license stuff left and right, so at the end of the day, it's hard to figure out who owns what and who has the right to distribute what data sheets. If A licenses something from company B to make a chip, A often doesn't want to give you the data sheet for fear of raising the ire of B. They t

    I've had a look at the forum thread linked at the very end of the article. Softmodding only works up to the Geforce 6x00 series. It seems that after that NVidia put in some more checks than only the PCI ID. As reported in the thread, there's no performance increase in professional 3D apps, and OpenGL is broken.

      Wrong. Here are instructions for softmodding a Geforce 8800 GTS:

      Also, the main thing you are paying for with a quadro card is support. You are given access to the driver development team. If you find a bug they will fix it in short time.

        There are problems though.

        It doesn't work with OpenGL extensions it does accelerate out the Direct 3d extensions though. It's not as fast as the higher memory capacity quadro cards. But its a huge increase over the stock GeForce.

        You still don't get the same tolerances as a standard Quadro. Granted the price is a lot less. But in a Cad Shop where you are consistently working on 200k+projects would you want to take the slightest chance of their being a rendering or upgrade issue? A day there can cost you

    The whitepaper says that Quadros have got support for window clipping, hardware accelerated clip planes, antialiased wireframe rendering, more memory, etc. Although it doesn't say if the hardware accelerated features do exist in the GeForce family but are disabled by software.
  • I recall a year ago or so borrow a Quadro 1300 from work (my video card bit the dust), and Civ4 and other games just sucked...until I force-installed the GeForce rather the the Quadro drivers for Windows.

    Not only was it playable now, I could turn the resolution all the way up;)

    Could just be a difference in the age of the drivers though. Quadro drivers are typically much more conservative performance-wise than GeForce ones and thus release changes much more slowly.

    This would be why they won't release the source to their drivers, then.
