Kicking off this week is SIGGRAPH, the annual North American professional graphics gathering that sees everyone from researchers to hardware vendors come together to show off new ideas and new products. Last year’s show ended up being particularly important, as NVIDIA used the show as a backdrop for the announcement of their Turing graphics architecture. This year’s NVIDIA presence is going to be far more low-key – NVIDIA doesn’t have any new hardware this time – but the company is still at the show with some announcements.

Diving right into matters then, this year NVIDIA has an announcement that all professional and prosumer users will want to take note of. At long last, NVIDIA is dropping the requirement to use a Quadro card to get 30-bit (10bpc) color support on OpenGL applications; the company will finally be extending that feature to GeForce and Titan cards as well.

Dubbed their Studio Driver: SIGGRAPH Edition, NVIDIA’s latest driver will eliminate the artificial restriction that prevented OpenGL applications from drawing in 30-bit color. For essentially all of the company’s existence, NVIDIA has restricted this feature to their professional visualization Quadro cards in order to create a larger degree of product segmentation between the two product families. With OpenGL (still) widely used for professional content creation applications, this restriction didn’t prevent applications like Photoshop from running on GeForce cards, but it kept true professional users from using it with the full, banding-free precision that the program (and their monitors) were capable of. So for the better part of 20 years, it has been one of the most important practical reasons to get a Quadro card over a GeForce card, as while it’s possible to use 30-bit color elsewhere (e.g. DirectX), it was held back in a very specific scenario that impacted content creators.

But with this latest Studio Driver, that’s going away. NVIDIA’s Studio drivers, which can be installed on any Pascal or newer GeForce/Titan card – desktop and mobile – will no longer come with this 30-bit restriction. It will be possible to use 30-bit color anywhere that the application supports it, including OpenGL applications.

To be honest, this wasn’t a restriction I was expecting NVIDIA to lift any time soon. Rival AMD has offered unrestricted 30-bit color support for ages, and it has never caused NVIDIA to flinch. NVIDIA’s official rationale for all of this feels kind of thin – it was a commonly requested feature since the launch of the Studio drivers, so they decided to enable it – but as their official press release notes, working with HDR material pretty much requires 30-bit color; so it’s seemingly no longer a feature NVIDIA can justify restricting from Quadro cards. Still, I suppose one shouldn’t look a gift horse too closely in the mouth.

Otherwise, at this point I’m not clear on whether this is going to remain limited to the Studio drivers, or will come to the regular “game ready” GeForce drivers as well. Keeping in mind that both drivers are essentially identical software stacks – the difference being their testing and release cadences – there’s no reason to think it won’t show up in future GeForce drivers as well. But for now, it’s only being mentioned in the Studio drivers.

Meanwhile, the latest Studio driver release, true to its purpose, will also include updated support for several applications, including Cinema 4D and Blender. So while the 30-bit color announcement is likely to overshadow everything else, NVIDIA is continuing to iterate on their software support as previously promised.

New RTX Studio Laptops & RTX-Supporting ProViz Software

Along with their latest Studio drivers, NVIDIA is also using the show to announce their partners latest hardware and software developments.

On the hardware side of matters, another 10 Studio laptops are being announced. The NVIDIA branding program, first launched at Computex earlier this year, set about establishing a minimum standards program for participating laptops. In short, the laptops need to include a 45W Core i7 and a GeForce RTX 2060/Quadro 3000 or better, along with a calibrated display. The latest hardware release cycle will see new laptops from Lenovo, HP, Dell, and Boxx, and will bring the Studio program to 27 laptops in total.

Meanwhile on the software side of matters, NVIDIA is celebrating the adoption of their RTX technology, as well as the additional applications that are adding support for it. According to the company, 40 professional visualization applications already support RTX in some form, with more to come. At this year’s show in particular, Adobe, Autodesk, Daz, and Blender are all showing off new software versions/updates that add support, typically for hardware ray tracing. NVIDIA sees RTX as an important product differentiator for the company, especially as it seems AMD won’t have comparable technology for at least another year, so it’s something the company has continued to invest in and is happy to tout that advantage.

    Thank you. After few attempts I managed to get it to work, but to be honest, I don's see much of a difference in PS:) Anyways, thank you for the help! Reply

    Happy to help! It's a hack that laptop owners have had to use for a loooong time if they wanted the latest drivers instead of waiting for their OEMs to release their "approved" versions.

    And of course the 10-bit support for non-Quadro cards will only make a difference if 1) Your screen supports 10-bit color depth and 2) You enable it within Windows/Nvidia Control Panel and within Photoshop its self (there is an actual separate option within PS that you have to enable). But even then it isn't always immediately obvious unless you work with gradients a lot.

    Largest benefit for work that doesn't use gradients is having a wider range of displayable colors so that the screen can display the exact color you want more accurately so that it's as close as possible for print/production. Because having your work come off the printer with a slightly different hue can be an expensive mistake if you send it to a printing house!

    Did nvidia use a 3dfx voodoo card to come up with that 24bit image? Reply

    It's written there it's simulated... Reply

    Don't knock the Voodoo...

    Mine topped out at 16 bit color anyway...

    So funny of Nvidia trying to show a 30bit image over a 24bit image over the internet with people having monitor that cannot show the difference. Reply

    Its like they made a 4 bit vs 8 bit image to show 24bit vs 30bit. Cute. Reply

    What it's actually like is that neither you or your first responder understand this was from a slide at a presser where people in the audience could see the difference, not something made specifically for the internet (but of course they will share the entire slide-show online, because they nearly always do).

    A better question is why AnandTech chose to include it, actually.

    If you don't have a monitor that can see the difference then there's little point in even reading the article, let alone complaining you don't have a monitor that can see the difference.

    I imagine those that do have a monitor that can see the difference then this is good news.
