    Can you see the card from this screen?

    yes it uses the 980ti in iray

    I got it using it in about my video card too by swapping my monitors as one was on 760

    Octane Render for DS 1.2 proving a PITA

    I like to skip generations in buying cards. I find that top level cards are still relevant for an entire generation (I have a 780 and it's fine compared to the new 900 series).

    The 780 is a good card, and even has about 60 more CUDA cures.

    However, those 60 more cores out of close to 3000 equate to a 3% difference; clock speeds however, are about 13% difference in the 980ti's favour.

    I never found any comparrisons with rendering, but others, including compute show the 980ti being a decent amount ahead of the 780ti. Enough to warrant the cost of the upgrade? That's up to you.

    Oh and the kepler card CUDAs (780) are not as efficient as the 980 maxwell.

    I just bought an alienware with Intel corei5 and a NVIDA Geforce 960. Not knowing this type of stuff , would that be suffcien for high(er) quality Iray renders?

    Hi,

    The quality will be the same regardless of the GPU, what will change is the amount of time it takes to render. The complexity of the scene and lighting play a big part in the render time. I think you will be fine and don't forget to have fun with it all

    Not, entirely true...

    Yes, it is completely true IF the render will finish before the limits kick in or if the limits are turned off.  But if they are at default, then yes, there can be a huge quality difference...simply because one is finished and the other isn't.  You are comparing apples to oranges, in that case, if you are not aware of the limits (time by defualt is 2 hrs...and a lesser GPU or CPU only render can take more than 2 hrs to finish).

    Your max goal will be 15,000 iterations in less than 1hour and 18 to 22 minutes.

    Zilvergrafix...I'm sending you a bill for a new keyboard.  This one is now covered in so much drool it 'squishes' as I type...

    Is that your render box?

    I did one Set to Iray ( at least i think i did ) it only took about a half hour. Let me see if i can post it here. I guess I still have a lot to learn about how this stuff works.

  • NewYorkKnightNewYorkKnight Posts: 45

    For some reason , i can't seem to upload it , but i did a comparison of the 960m compared to 980ti , and whil the 960 is only a quarter of what the 980 is , it's still no slouch. I guess i can always upgrade in abourt a year or two. That's all i really needed to know. It won't give me exactly what i want, but it'll be close.

    Isn't 960m for laptops?

    Absolutely agree. If one render is not finished it will not look like the one that finished. But when both have been allowed to finish they should be the same the difference being the amount of time to finish. Thanks for making it clear that there are parameters that can affect the final render and we all need to be aware of that. I hate it when I let a render run and I forget to set those parameters.

    Yep, mine, a virtual one, but mine,

    It's a Sketchup prop created for other dude, exported to Luxion Keyshot for OBJ import, Sketchup does wrong Obj imports to Daz, Keyshot does better.

    I was trying to get rid of some artifacts/graininess in some shadows. so left it rendering over night. I use a 980ti and a 970; I upped the time and itterations way past max (they can be changed).

    I stopped it at 94% converged - ish.

    Iray INFO - module:category(IRAY:RENDER):   1.0   IRAY   rend info :     CUDA device 1 (GeForce GTX 970): 7319 iterations, 76.477s init, 33030.323s render (over 9 hours).
    Iray INFO - module:category(IRAY:RENDER):   1.0   IRAY   rend info :     CUDA device 0 (GeForce GTX 980 Ti): 30323 iterations, 66.560s init, 33039.987s render

    As mjc1016 states, making sure whatever card you use has enough time to finish, is a good idea; just be aware it can burn through some electricity doing it. Sometimes, rendering at a higher resolution than required and reducing will do what you require.

    Nvidia and Geforce

    So a tad confused. According to WikiPedia, Nvidia invented Geforce and that is a particular GPU architecture. However I see on Newegg.com all sorts of GPU products that are Geforce, that are made by other manufacturers. I assume they are licensing the architecture from Nvidia. For Iray rendering, does it have to be an Nvidia GPU, or will a Geforce GPU made by someone else work?

    Thanks,

    Treebeard

  • barbultbarbult Posts: 24,720
    GeForce made by any manufacturer will work. I have an EVGA brand card.
  • Kevin SandersonKevin Sanderson Posts: 1,643

    Nvidia makes the reference card and the other brands tweak it with fan configurations, etc. Most are made by PNY according to one of the DAZ guys to the brand spec anyhow.

    "GeForce" is the brand name that the company "nVidia" licenses out for implementations of its reference designs.  A "GeForce" video card will be nVidia chips.  Any hardware manufacturer (EVGA, Asus, Gigabyte, Zotac, MSI, etc.) can license the name an release a card based on the nVidia hardware and reference designs.  Any "GeForce" card is synonymous with "nVidia", though the card may not be made by nVidia itself.

    I have an iMac running an NVIDIA GeForce GTX 780M, 4Gig VRAM, 1536 CUDA cores.  

    I'm very happy with the speed of rendering. I wish I could say I was equally happy with stability, but alas, I tend to end in system crashes particularly if I interrupt too many renders in a row without restarting DAZ.

    I get the impression this is a Mac OS issue, not an NVIDIA issue, so don't let me scare you away from the Windows version of the card. It's ample for very large scenes, including 8-10 characters. (Maybe more; I haven't tried.)

    will that render render faster if you disable the SLI on the model?

    Hello, does anyone know if DAZ supports the new GTX 1080 cards?

    No, it needs a driver update from nVidia - said to be due "SigGraph time".

  • 3delinquent3delinquent Posts: 355

    The drivers for the 1080 series do not currently support Iray. Suggestions are it will take a couple of months yet.

    dunno how to do that, and sorry for the super late reply blush

    Does anyone know when DAZ will support the Nvidia GTX 1070?

    Presumably it will be supported when nVidia releases suitable drivers. It's possible that an Iray update will be required, but that is not the impression I have gained; if it is the case it will depend on when nVidia provides Daz with an updated version of Iray which will then need a period of testing before full release (but again, I am under the impression this will not be required).
