Maybe you found a memory leak.
Pay attention that Pascal Titan X will need a different display driver than your older cards to make the cards work all optimal so you will have to install them separate with own drivers and when used for the same task together with old series cards at once you will lose on permanent and GPU scaling of you Pascal Titan X card , you get some extra boost but it will be not optimal so waste money vs permanent
Titan X are still on sale from $850 to $1040 I think even Newegg still sell it I saw 2 days ago , if I was you I would sell the old Titan X card and go for 2 Pascal Titan X or get myself additional Maxwell Titan X to complete your rig optimal without driver conflicts
That's what's killing me, Maxwell Titan Xs are still going for more than I would expect. If only Iray worked for Pascal now, I could get two Pascal Titan X to replace the Maxwell Titans, sell those Maxwell Titans and my upgreyyyed cost would be a lot lower vs. letting the Maxwell Titans depreciate.
But if I did that, I couldn't render.
That's the problem , you will need to wait little longer , the prices for Maxell Titan X will not drop down so fast , how less is on the market how higher the price ..weird but true so you can still make some cash selling it later when iray is ready for Pascal .
I hope so, that will take a lot of the sting outta the purchase!
Did anyone have any luck ordering a Pascal Titan X in a Nvidia store?
- - -
I was updating drivers on some other workstations and while looking at the Geforce Experience screen the banner for the Titan X and a link to the Nvidia.de store popped up.
It did say
- available, on stock
- only allowed to order 2 per customer
- delivery in the next 2-3 days but only inside Germany. No distirbution to citizen of other neighbour countries.
Called nvidia.de customer support.
They told me to contact their usual vendor partners in Switzerland but they had zero information which reseller would be distributing.
None of the distirbutors contacted by phone had received any information about a Pascal Titan X.
Only one supplier actually asked me to write them an e-mail and they would investigate further if and how it would actually be possible to order.
Everyone else pretty much shrugged with their shoulders pointing out that if it is not in their online store it is not available for ordering...
- - -
-> To me it looks like that distributing cards only over the nvidia store may only be working in huge countries that have their own stores.
Now customers living in smaller countries without a dedicated Nvidia online store are at a disadvantage.
Curious to find out how long it will take to bring those distribution partners up to speed...
I'm REALLY tempted, they show in stock - but how long before we have Iray support for Pascal cards in Daz Studio?
FROM DAZ3D
I thought developers already had builds of the Iray 2016.2 SDK?
But if the case is that If the SDK doesn't get to DAZ's hands until September, how long until it's in Studio?
As you read they can't just jump from one build to another so they go slow with the progress they planed ahead, DAZ is always ahead with builds from us even with betas , DAZ need to make little changes to studio itself as many things changed beside only pascal support so they need to make sure everything works ok .. Nvidia said in the fall so I just assume later September early October when everything is ready , iray plugins are ready for 3dsmax I think this week but we don't use plugin in DS
I told you guys from the beginning that display driver will not fix this and it will take much longer but did not expected that long , I am curious about the new updates and features and plan a new mini Pascal rig as well so I wait first for the benchmarks from 3dstudiomax with the plugin to see the performance of the slower cards.
...exactly. I used to work in programming. I really hated it when people, who didn't understand he complexities of coding and debugging, expected instant miracles.
...and when they didn't get them, they would be mad at us.
Usually the developers have the early builds so that they can release products in sync with each other or close to it.
With life cycles of only a year or so, I don't think its too unreasonable to expect functionality in a few months or less. Tesla has been out sine April I think, GTX 1070 and 1080 for about two months, now Titan X.
Maybe not a big deal for me, as I tried Battlefront in SLI again and it might be OK. If so, only took 9-10 months to do it.
Or, if you can't wait until September, Octane 3.03 already has support for Pascal cards
Octane isn't optimized for Pascal yet, but it is up and running, and running quite well. The quote below is from Gain on the Octane forums to give an idea of rendering performance. Keep in mind that Octane has not been fully optimized yet for pascal, but the results look good with a 1080 close the same performance as a 980ti. Also, Otoy doesn't use the rendering SDK from Nvidia, so Iray performance might be much different.
I actually have an Octane 2.x license, but I'll stick with Iray now. I've bought a lot of shaders for it. (Plug for Mec4d, I have her PBS shaders 1 & 2 and they are excellent!!)
I come from using Poser with Octane, but the plugin only brought textures over to Octane. My workflow using Poser & Octane is soooo much slower any performance benefits won't be realized unless I render the same scene from like 50 different angles.
I don't know if the workflow is better with Daz & Octane, but Iray has been suiting my needs. I feel spoiled now buying things here made for Iray and have them render nice out of the box rather than having to waste lots of free time jacking with the shaders to get it to render right.
Same here lol I just focus now on one thing easy out of the box ,, I have Octane standalone, DS plugin and Poser plugin for Octane that I helped testing for you guys and then iray took all my attention and I returned to the mothership for good ... ;)
Like the Octane plugin for Poser, you still need to work with the shaders a bit with Octane for DS
. But, with the current version of the plugin, the Iray shaders come across much better than the 3Delight did for skin. Attached is an image I'm playing with to give you an idea how well they translate. I haven't touched the skin shaders at all yet, the specular is a bit high, but otherwise not too bad.
I'll admit to being a bit spoiled by all of the Iray content too. I don't use Octane nearly as much as I used to, but there are a few things (like out of core textures) that still make Octane a good investment for me, it doesn't hammer my system as hard as Iray, and I have the Carrara plugin too (dynamic hair ... wooohooo). Besides, even with all of the great Iray shaders, I still end up tweaking most of the shaders to get the perfect look, the skin shaders are usually the most time consuming (I'm seriously thinking about getting the RedSpec skin shaders to speed the tweaking process up a bit for non-Iray G2/G1 figures).
Yes, MEC4D's Iray shaders are awesome!! There are many other outstanding shaders available for Iray too that simply make things much easier, especially for kit bashing!!
The 1080 is impressive, especially when it is also the display card, and the drivers are not yet optimised.
I know its really temping from a dreaming point of view to be drooling over all these things. I know i am too. The plain fact of the matter though is when there is a huge shift in tech with programs we use its better to wait for the smoke to clear or we end up pulling out our hair and having hardware laying around our houses in boxes collecting dust.

Just bought the nVidia GTX 1080 G1+EVGA 80 Platinum 850W PSU+ 32gb G-SKILL 1866 RAM+WD 8TB external drive=$1289 tax incl
Money well spent as I'm upgrading from an AMD r9 290x a 6 yr old Thermaltake 750W and 24 gb 1600 Kingston RAM! I'll finally be able to properly use iRay, and maybe go the Mec4D route and plunge into the wonderful world of Octane render!
LOL, I never drove in my life for that very reason!
You can easy add one more 1080 in the future with that new upgrade .. nice !
you see when people compare Octane speed with iray they make major mistake using default direct light in Octane vs Indirect Photoreal mode in iray in place of iray interactive mode what is the same as Direct Light in Octane .. GPU scaling with multiple cards is much better and faster than in iray , so for the best test 1 card need to be used for both engine comparison , plus as closer as possible shaders or simple surfaces , my iray shader maos can be loaded into Octane for PBR rendering as well values .. as I use uncompressed values so universal for most all programs .
...so you're saying that the "quasi-biased" version of Iray is similar in performance to a 600$ render engine (including plugin).
you see you don't know what I was talking about .. do research you will know better
btw iray 1 year license cost $295 per person where Octane standalone around $300 and is actually cheaper , I am sure you would not see difference if I show you some interactive renders vs photoreal , Octane have also the "quasi-biased" mode on default where iray default in Studio is Path tracing . When you use 1 card in iray or Octane it works at 100% speed in both, but with more than 1 card Octane GPU scaling is better that why it process the render faster .. the light is all the same when you use the same HDRI
I don't want to go into conversation about what is better as it is not about ... I just see people comparing stuff on the internet doing wrong way and using the wrong rendering modes in comparison.
Yeah, keep in mind that with the higher cost of admission renderers, I think you wind up with more talented people putting effort into shaders and stuff. Octane has some really good shaders in it's library, and lots of great info in their forums.
Being a lowly hobbiest like myself, when I get a good Iray shader, or put the effort into tweaking shaders and lighting there I don't see much difference myself.
The rendering technology is not much different and the principle is the same , my iray shader used in Octane deliverer the same result as in iray, there are just additional stuff in Octane that I miss in iray , plus not all functions that iray have are added to DS , but when you look on the naked engines in both programs there is no much difference and if everyone keep the PBR rules as the do using Octane the results would be perfect and at the end you still have an eye of an Artist that make the best stuff with , something we can't buy with money as it is not included but you can learn with practice as all you need is a little passion for your hobby to begin with .
...but your post seemed to compare Octane's GPU/CPU render setup with Iray's Interactive mode.
I don't compared anything , I just mentioned that Octane have also different render modes as iray have so if someone compare a rendering time should use the correct rendering mode as the speed is different with different modes , what have nothing to do with GPU/CPU setup in this case , when you use 1 card it is used optimal in iray as in Octane the huge difference is when using multiple devices but this is not about that.
the default Octane render mode is like Interactive render mode in iray what is very fast since it is Direct Light mode that does not render volume so what some people do is comparing the fast Direct Light mode with the path tracing photoreal mode in iray and that is the wrong way to compare the 2 engines rendering speed . comprende ?
..so then Octane's photo real mode (or whatever it is called) would either require heftier GPU resoruces just like Iray, or be just as slow in full CPU mode then?
@ Octane
OctanePMC and Iray Photoreal are the final image render modes.
I will not go into arguing which is faster.
Nevertheless what can be said without a doubt and is at least remotely relevant in a topic about a new GPU.
GPU scale in a linear way in OctaneRender directly tied to the amount of Cuda cores. If you have two GPU your render is finished in half the time. If you have four GPU your render is finished in a quarter of the time.
1 GPU = 60 min
2 GPU = 30 min
3 GPU = 20 min
4 GPU = 15 min
As far as I gathered from other threads this is not the case with Iray and you will not see that much speed improvement when using 3 or 4 GPU in Iray.
Not at all.
- - -
Octane PMC is the recommended kernel to render your final images.
I do agree that people should not compare a preview render mode of render engine A to a final render mode of render engine B.
- - -
- Direct Lighting is used for faster preview rendering. Direct Lighting is not unbiased but is useful when creating quick animations or renders.
- Path Tracing is best used for realistic results (together with PMC). The render times are higher than Direct Lighting but the results can be photorealistic. It can have some difficulties with small light sources and proper caustics (for which PMC is better suited).
- PMC is a custom mutating unbiased kernel written for GPUs. It allows for complex caustics and lighting to be resolved.

Update / Edit:
I break up this post into two to make sure for each topic there is a dedicated post.
@ Pascal Titan X
One week after Pascal Titan X launch Nvidia customers in most larger European countries were able to order a Pascal Titan X directly from their countries Nvidia store. Unfortunately Nvidia neglected to prepare the launch properly and now customers living in some countries are still not able to order trough official distribution channels.
To recall the announcement was the following:
Source:
https://blogs.nvidia.com/blog/2016/07/21/titan-x/
As it turns out Nvidia was not able to ensure equal distribution of the Titan X in the European sales region.
All those countries who do not have a Nvidia store of their own like Switzerland, Lichtenstein, Luxembourg so far still have not received an official way to order.
The absurdity of the situation is the following
- The "select system builders" all official Nvidia partners in the countries in question at first had no information at all and now after a week they received information that they will not be able to distribute Pascal Titan X
- If you would live 100 miles south, north, east or west you could actually order from an official Nvidia store.
- If you do not care about tax receipts, warranty or official distribution channels you could just ask your friends and family living in one of the larger countries with Nvidia store to order for you.
Some people may even use that to circumvent the ordering limit of only two Titan X per person.
-> The Nvidia store order exclusivity has achieved the opposite of the communicated intended result.
Nvidia communicated clearly that the Titan X is not just a pure gaming card and they introduced an ordering limit to make sure the limited available stock is distributed equally to ensure researchers and commercial users get their copies and not just gamers.
As it turned out researchers and commercial user who need to stick to the official distribution channels and trusted Nvidia are left empty handed.
At the time of writing it is still unclear if and how Nvidia customers living in those countries are supposed to order.
- - -
Please Nvidia stop releasing GPU in Nvidia online stores exclusively if you cannot ensure that all customers in all countries of a sales region are able to order at the same date.

Thanks @linvanchene
To translate it for iray language for people that still wondering
Octane- Direct Lighting = Iray- Interactive mode
Octane- Path Tracing = Iray- Photoreal mode
Octane- PMC = Iray- Caustic or Architectural sampler On together with Photoreal mode
so if I render a scene in 3 sec using Octane Direct Light and compare it to iray scene rendered in Photoreal mode that take 20 sec of course it is slower , and that was all about
My iray rig render time would be like that
1 GPU = 60 min
2 GPU = 30 min
3 GPU = 15 min
4 GPU = 7 min
a perfect GPU scaling 100/50/50/50... sometimes when using 2 cards the ratio is 100/76 % or 100/50% faster depends of materials but never lower than 100/50 % with 2 cards
preview iray version had some issues rendering smaller scenes with multiple GPUs but the issue is fixed and in the last BETA the GPU scaling is just perfect with all 4 cards . in the last General release GPU scaling was perfect with just 2 or 3 cards and optix off , with optix ON the GPU scaling of 3 cards result in the same speed of 2 cards like the card was just not there at all . in The last Beta 2 or 3 cards need still the optix off , but 4 cards need the optix ON for perfect GPU scaling , the viewport also improved without clipping when using 4 cards and small scenes with the iray engine 2016.1.2 since iray engine is catching up fast and the new upcoming 2016.2 is even better
