pascal + iray news of the day

from an Admin on the Nvidia Advanced Rendering Forum today:
The Iray version with compatibility for Pascal GPUs just passed acceptance and will now make its way into the various Iray applications. We will be updating the Iray plug-in products as soon as we can. You can expect to see Iray for Rhino coming out first, along with a Beta of Iray Server 2.1 to use with it. Iray for Maya, 3ds Max and Cinema 4D will follow (likely in that order).
While a delay in supporting a new GPU generation is common, this long of a delay is not, and for that we sincerely apologize.
NVIDIA is taking strong note of what happened this time to minimize the chance of it happening again.

Greetings,
I have a whole new Windows machine with a 1080 in my wishlist, just waiting for DS Iray (Deus Irae?) to be upgraded to a version that works with it.
...well, it's also probably going to be used for VR, but...yeah, mainly rendering. :)

I didn't wait. Got my new computer, with a 1080, last week. The cpu is so much faster, (not to mention 8 cores instead of 4,) that my CPU Only renders are about 5.6 times faster than the old computer. I opened a scene I did over a year ago, and rendered it for 6 hours each on both computers and compared the number of samples/iterations to come up with that number. I'm rendering a rather complex scene right now that's rendering at a little over 1300 samples per hour. While it was still a WIP on the older machine, with fewer objects, I let it render overnight and got less that 250 samples per hour.
So what I'm saying is, depending on the specs of your current computer, it might be worth it to go ahead and get that wishlisted computer now. Not to mention, you'll have all your programs installed and content moved over before the update. I've had the new computer for nine days, now, and I still don't have everything set up in DAZ Studio—custom actions/scripts, custom menus, etc.—as they are on this computer... too busy "working" with new "tools," computer and content...
...the title of the thread gets me thinking there should be a soundtrack loop of teletypes in the background.
Yeah looking to slap a 1070 or 1080 in my workstation. Even though it has PCI 2.0 x16 slots it would still be a huge improvement.
After that quote, I'm not convinced, but haven't bought the new cards as want to see folks speed comparrions; I'm not believing the hype from Nvidia; hype is sales-speak for bend over and get ****.
Thank you for sharing.

Great, my new system including a Nvidia1070 will arrive in mid November. Good news !!!
(...As long everything in DS is updated by then)
Pretty sure Maxwell cards were made before Iray in DS.
- Greg
I don't think we had an issue like this - as I recall the previous generation of cards were available before Iray was added to DS, at the beginning of last year.
Yep;...Pascal is the first post-Iray card release. And as seen, everyone is in the same boat...even the 'big boys' were waiting for this release.
...for any who dropped the big Zlotys on Quadro P's, I can imagine there's a lot of snarling and gnashing of teeth going on.
My guess is that there aren't that many bought them for just using Iray on...and this hold up is mostly affecting Iray....but it is afftecting ALL Iray users.
Quadros are normally not purchased for rendering, but for high powered computations coupled with visualization. Iray does not need, or use, the excess power provided by a Quadro or a Tesla -- that being double-precision floating point, non-blocking bus control, multi-card communications without SLI, and in the newer cards "deep learning".
However, if one does have the correct hardware on the MB, a Quadro will put out performance numbers per CUDA that are significantly higher than the same chipset on the GTX series of boards. The exception to this rule is the M6000 24GB, which has been deliberately crippled for some inexplicable reason.

I always understood the benefits of quadros were derived from Nvidia's drivers for specific professional applications, not from motherboard features, especially from features that already exist. Can you elaborate?
Oh, I forget that Maxwell has been around that long.
But even so, the timeline between Iray being announced and released, and when it hit Daz3d, could be helpful.
I'm also wondering if Pascal Iray is being held out for a new version of Daz Studio, and we wont see Pascal Iray until 5.0. Because it looks like this is more than just simple driver support, it looks like a while new version of Iray.
If its a whole new version of Iray and it comes out with version 5 of Daz Studio what happens to all of us who can't upgrde their video card?
Haha Version 5 of Daz Studio lmao and pigs can now fly... as long as its taken them to get to 4.9, they better release iray support sooner rather then later
Since the change log ( http://docs.daz3d.com/doku.php/public/software/dazstudio/4/change_log#private_channel ) shows:
Update to NVIDIA Iray 2016.2 beta (272800.3649)
in version 4.9.3.92, it seems unlikely that they would need to break the SDK to incorporate the new version. And I think it unlikely that NVIDIA's final version of Iray 2016 would work ONLY on Pascal cards, or that Daz 3D would release DS with such a limitation.
It will work just fine. Look at Daz 4.9, it has an updated Iray engine, and this required Daz 4.9 to use. I am saying that 5.0 will do the same thing.
And to be clear, this is just my personal theory. But I feel very strongly about it. That's also why I think it will be a while. I could be wrong, and I happily invite Daz to prove me wrong.
i just got a new pc with a gtx 1070 in it and i really wanna try it out in daz studio, sooner rather then later
I never said that it be exclusive, did I?
No, Ice Dragon Art was worried that it would.
Just checking. I have no idea how the tech works. Never hurts to ask.
Nope. It was possible to unlock certain Quadro "features" on GTX series using specific hacks, but one never could achieve the performance of a Quadro because part of the extra cost on a Quadro card is a controller that allows a Quadro to communicate with the MB chipset without locking the PCIe bus if the MB has the capability. On Xeon motherboards and especially multi-processor setups, the Quadro card can negotiate with the onboard bus controller to segment communications without disrupting the rest of the bus. This allows the Quadros/Teslas to not only communicate faster (and avoid stalling the host system), but to competely operate independently of the PCIe bus for internal computations.
There are other pieces that justify the costs of the hardware that aren't driver related as well but they are beyond the scope of this thread. (one of which is how nVidia can clock a Quadro slower than the "equivalent" GTX yet still achieve higher performance).
Kendall
...I thought straight computation and deep learning was what Teslas were for. One Supercomputer under development is is using the 16 GB HBM 2 Tesla 100s and NVLink.
...which is why my optimum workstation is designed around a dual socket Xeon MB.
Also I would imagine that the P6000 is not hamstrung like the M6000 is.
Teslas do not have display units on them, but they are CUDA GPU's the same as what are on the Quadro cards. In fact, it is possible to install a standard Quadro into a standalone Tesla unit and have display out from it (I have one set up like that right now)*. I have several Tesla Units here and those that are Compute Level 2+ work just fine under Iray. Teslas do tend to have more RAM on them, but that is simply part of the cost that one pays for the buggers.
EDIT: Caveat: By "standard" I mean with output ports. The Quadro must physically fit in the standalone unit's rear slots to expose the ports, which may mean removing it from the casing to install and using the cooling in the tesla's casing to keep the heat down (which is normally not a problem unless the fins on the Quadro are facing perpendicular from the air flow in the case)

I think iRay was first released in 2014, although it was 2015 when it first arrived in DS. Maxwell arrived in September 2014, so given the development lead time, I suspect that iRay was created before Maxwell arrived, and was then updated to support Maxwell. That is what the developer briefing at the top of this thread implied. Remember that iRay was not created for DS, and was incorporated into over 3D apps first.
If you dig through the Nvidia docs, there's no specific mention of needing Maxwell support, so it was either built into Iray when released (before the cards) or there wasn't enough of a difference between Mawell chipsets and later that it needed any extra/different support.
