I am seeing rumors that the GTX 1080 TI is going to be announced sometime in the next 2 weeks. Apparently it has 10Gb of VRAM with 3328 Cuda Cores.
I was planning on buying 2 of them next month if they were available but from what I am seeing with the 1080 I may hold off. Currently my 2x 980TI's are keeping pace with the 1080's. I would have to see a huge increase in performance if I were going to throw down $1500+ on a new graphics setup.
All I can say is they better get it togather if they want my money. I am willing to pay big bucks for better performance but it needs to be a big increase that is worth the cash. Gaining a few minutes in performance per an hour of rendering is not worth $1500 to $2000.
Considering the new cards are comming out and the last ones still are not officially supported by DAZ and they don't perform and better than the 980TI from a year ago. I am not convinced that it's worth bothering with.
I've been using a 1080 with the beta version of 4.9.3 for several weeks with no problems other than crashing when optix acceleration is used. Apparently, this has been fixed for the latest beta, 4.9.3.166.

Cheers,

Yeah I have read the thread and that is great news but it was 6 months before a beta came out that allowed them to work and even then they are not supported in an official version of DAZ studio yet. Also they are not any faster at rendering than my year and a half old 980TI cards.
If I had bought two 1080 cards for $1500 I would have been out of luck for 6 monthes only to get the same performance I already had with my 980TI's using the latest beta version of the software. That is a lot of money spent and alot of time down with virtually no performance increase what so ever. Obviously I am concerned and skeptical of the next cards comming out after the launch of the 1080. I need more performance I just hope they can deliver this time.
Two things to keep in mind. Most of the delay was on Nvidia's end. And two, performance gains will also be in Nvidia's court...driver and Iray updates.
And there is the fact that 1080s, a new generation card, come with more memory, use less power and generally do as much/more than the 980Ti, in the 'non-Ti' version. Not all upgrades are going to add blazing performance increases...some will just add a general 'more'.
My 1080 performs at about the same level as my 980TI - within a couple of iterations and a few percentage points of time (sometime a bit faster, sometimes slower). The 1080 dows this with an additional 2 GB of vram and uses significantly less power.
And, AFAIK, the Iray version in the current public beta is an Nvidia release candidate - not a fiinal release. So the ball is still in Nvidia's court. I expect to see a proper release of Studio a week after Nvidia gives DAZ a production release of Iray.
I see a lot of reasons/excuses (a bit of both) about why 10 series cards are not up to scratch. None of it is Daz's fault, but is down to Nvidia.
Do not be fooled like I was. the new pascal GTX card per nVidia do not support Iray only their Quadro cards do, and gues what they do not work in DAZ becuase like a fool I bought the P5000 card. While the beta version of DS 4.9 does put a load on the card it does nothing to increase the rendering speed;. Per DAZ the as of this date in 2017 they have not even got a Pascal card becuase get this "they cost to much". Since the GTX cards do not work I guess DAZ never bothered with the Pascal chip. It is unlikely in future that DAZ will even support Iray. Daz refered me to Octane but they have not responded if they support the Pascal chip as it is not listed on their web site
Wrong, wrong, wrong...
First the latest Quadro cards ARE Pascal based. Second, yes, it does work on Geforce cards...it's just that Nvidia 'recommends' Quadro cards. And third, the release version 4.9.2.70 was released BEFORE the Pascal card and the version of Iray bundled with it did not support ANY Pascal card (Geforce/Quadro). The newest release 4.9.3.166 (just released today, BTW) DOES include Iray 2016.3...the latest release version that DOES support ALL Pascal cards.
+1 - I have a GTX1080 and can confirm it works in Todays new release (& the Beta Version)
I think someone needs to do a bit more research. 1070 running fine here
I really do wish you are right. My info comes directly from Nvidia where a tech told me none of there current pascal chip GTX cards support Iray, and Iray is there product but if you are getiing jet like render s then I guess they lied to me. Alos I have been going round and round with DAZ tach support as late as 2 weeks ago. At no time did the contradict That the new GTX cards would no longer support Iray. I bought a Quandro caards and DAZ tech had me install old Beta version of 4.9, I could confirm that, that program at least puts a load on the card, but the speed was no faster than a CPU only render. In my last email with DAZ.
However DAZ stated they worked out GTX problems in email, so somebody is lying to me. DAZ said:

Hi Steven,
You are actually the first to report an issue with the P5000 card, so it may take a minute to get some traction. However, the devs are looking at your logs and doing what they can to find the machines to test on. We just recently worked out the known issues with the 1070 and 1080 cards. However, we did get it figured out, working with NVIDIA. Please be patient as we all proceed into new territories.
Please let me know if you have further questions.
Thanks,
Crissie
As to my P5000 problem DAZ basically told me to pount sand as they do not have card to test and it costs too much.....

Hi Steve,
It is indeed a disappointment to have such a nice system and not be able to use it the way you would like to. I do apologize for the inconvenience. Unfortunately, we would need a number of users reporting the same issue before we could get approved to get a card this pricey.
You may want to research octane renderer for Daz Studio. I have heard from a co-worker here that that may be a better option for rendering.
Please let me know if you have further questions.
Thanks,
Crissie
Story of my life I have a newer computer which had a Titan X which broke, Manufacturer offered 1080 and I agreed to put another one in. I did a remote test render and the was no load being put on the cards. I called Nvidia and tech was the one that informed me that GTX cards no longer supported Iray. So I upgrade to card they say supports it, and it still will not work. I will tried the newer version and hope it is not just a final varsion of the beata version which does not work for my card. Am trying to find out about Octane as work around but there web stie does not list the Pascal cards. Forums said 1080 will work but nothing on p5000. I downloaded demo and either I did something wrong but all render funtions apear not avalable in demo, even though the have size restriction and watermark. This makes no sense to me.
edited to fix quote
I can only repeat - Iray does wor with consum,er line cards, if nVidia says it doesn't (rather than that they recommend Quadros) then the information theya re giving is incorrect. As of the release of 4.9.3.166 DS does support Pascal chipsets, both in GeForce cards and in Quadros.
My 1080 has been working since the previous beta and works just fine in the current release of Studio.
nVidia tech. support upselling you a Quadro is one of those inevitable things, like the sun rising tomorrow.
Does anyone have video on the performance of their new card in Daz with iRay? I'd like to see how well it works.
These benchmarks look impressive.

I have a question about the GTX 1080, which I have... happy with it so far. I invested in two DisplayPort to HDMI cables. I have two Viewsonic monitors. One new and one about 2 1/2 years old. Both support HDMI. I'm kind of an even Steven sort of guy though. So I wanted to make used of the DisplayPort's in the back of the card. So this AM I got busy and switched out the DVI to HDMI on the newer monitor with the DisplayPort to HDMI and the older, bigger, MAIN monitor ... switched out the HDMI to HDMI with the other Displayport to HDMI... booted the computer and only one monitor came on. What a mess because all the icons and other stuff was shoved over to the main monitor. Played around a bit with the cables and now have both working but ended up with the HDMI to HDMI on the newer, smaller monitor.
Any help in understanding why only one monitor works with these DisplayPort to HDMI cables? I know I shouldn't worry as I have both monitors working but still want to understand what may be going on...
One of the problems with DisplayPort (which I discovered, to my chagrin) is that it doesn't handle the monitor being off or the computer being off very well. Or perhaps it's just the driver that doesn't handle it well. When I would turn off the monitor I had connected via DP, Windows would automatically go back to single-screen......moving all the icons, rearranging due to different resolution on the other monitor, etc. Very frustrating. HDMI and DVI don't suffer from this, as they don't detect whether or not the monitor has power, only if there is a connection.
I too am running into this issue. After upgrading to 4.9.3.166, I loaded a scene from 4.9.2.xx and rendered it without making any changes to settings. The good news is that the rendering time was drastically reduced from 7 minutes 41 seconds to 3 minutes 37 seconds, but the render is much more grainier. Any ideas on why this would happen?
hi, I bought a gtx 1080 with iray rendering is slower than the GTX 970 ?, please help me! thanks!
ALL GTX card works with IRAY (in DAZ), iray SERVER (with queuing or directly providing a .mfi files in the folder iray server will monitor). it WORKS. I use it, it uses all the gpu vram and gpu cores it can
LATEST DAZ Studio and LATEST iray server with LATEST (or recent) nvidia drivers will able you to use a GTX pascal latest generation (1080, 1070 and so on) for gpu rendering.

What nvidia support tries is to push you to go to the professional line : quadro / tesla. Yes, technically, that are the cards made for intense and heavy workload : rendering non-stop. Yes they do have some features not available in GTX and some features only available with the quadro/tesla drivers. For example streaming in iray server (not the same thing than queuing).
For most or, I do think, ALL needs of hobbyist or even semi-professional independant DAZ studio users, GTX will be just fine and will even allow you to use iray _server_ if you pay the iray server licence ($299 by year).

About performance. I'm not so sure a jump from 970 to 1080 will give you a dramatic improvement. (also you need to think about vram and number of cuda cores). Still pascal card are interesting because if I'm not mistaken, they are more energy efficient. Also there is risk of regression and bugs. Yes I know, these cards are sold since april but cuda support was only in summer, iray support was only in september/october, DAZ studio was only in january and so on. The industry is slow, engineers are slow, people are slow, I am slow too.
For my part, I'll wait at least the GTX Titan X pascal is less expensive or replaced by an even more powerful card to jump from the previous generation to that one.
Does anyone know how to purge the memory on the GTX cards when they become full and Daz switches to CPU only? Without shutting down Daz and restarting it again?
I know to shut down renders etc because they are consuming the Vram, and I usually only keep one open, and that is so that I don't have to wait for a new canvas to be created each time, but sometimes even then it will switch over to CPU on the second render, or not, depending upon how it feels today. I have to save my scene, shut down Daz and then restart it, then load that scene, then render it, then wait for the first canvas to be drawn, just to see if any change I've made to my scene looks ok. The alternative is to wait while the CPU processes the scene, but if I want to see how it looks fully rendered, I'd rather reboot and use the GPU.
So, it would be great if I could just purge the memory without having to reload the whole thing. It seems to me that if I shut down any open renders that the memory should be released, but in Beta 166 once it switches over to CPU, there is no going back to GPU after you've shut down any open renders. It's just locked into CPU mode from then on.
So it appears that there is no way to release the GTX 1070 Vram from Daz 4.9 without closing the program and then reopening it and reloading your scene. I find that kind of pathetic. I've searched the web and everywhere I look users are complaining about this issue and yet nobody is explaining this or offering a solution. It seems to me that it should be a simple thing for Daz to either release the vram if you close renders, or provide a button that manually releases it and turns the GPU on again. I've been in the habit of only keeping one render open and closing each new one I try, and sometimes that works for a while, but then suddenly, out of the blue, the card will be shut off and Daz switches to CPU. Once that happens, there is no way to clear the card other than to shut down Daz 4.9 and start over. It's stuck in CPU mode until you do a cold reboot. That really isn't the way a good program should work.
I've found that turning off the Optix Prime acceleration usually does the trick.
Daz didn't write the Iray code, and can't - as far as I know - alter it so fixing this issue isn't in its gift.
But shutting down Daz 4.9 clears it. Doesn't that mean that Daz 4.9 is reserving it and shutting it down is releasing it? Why does the Iray code have to be altered? Can't Daz simply turn off and on again that which is in it that releases the Vram when Daz is shut down? Why can't daz just do that part without having to actually shut down completely?
Thanks, I'll certainly try this :)
Some people have found that they need a system restart to free memory.
I have found this last to be true. My computer will stop rendering properly, will not render preview, all I see is the texture-less model (looks like Silver Surfer), until I reboot computer and everything is fine again for awhile.
Nvidia GTX 1080ti was announced last night at the GDC and goes on sale next week for $699.00. It has 11GB of GDDR5x running at 11Gb/s (vs. 10Gb/s for the Titan XP) and has the same number of CUDA cores as the Titan X Pascal, 3584. They've removed the DVI port so you get more air flow out the back. Wow.

I was using two 980TI's in SLI and decided to replace them with two 1080TI's. Then I remembered that I have a 3rd PCI express slot on my motherboard so I kept one of my 980TI's as a third card.
I pulled up a scene that I had done earlier with my 980TI SLI system. I rendered 2000 samples at 4K resolution with a 98% convergance ratio in 1 hour and 6 minutes. I just ran it again with my new setup and it took 33 minutes. Literally twice the speed of my last setup! This was everything I had hoped for. The number of cuda cores went from 5600 to 10000 which is not double what I had before but the new cuda cores are indeed larger and faster than the ones in the 980TI.
I downloaded the latest version of DAZ as soon as I installed my new cards and everything worked perfectly first try. I am very happy with the DAZ support and the Nvidia performance.
Here is a pic of my new setup.
