Graphics card help

in Technical Help (nuts n bolts)

Hey all, I recently ordered a new PC with a GTX 1080ti with 12gb ram. ( https://www.overclockers.co.uk/zotac-geforce-gtx-1080ti-mini-11264mb-gddr5x-pci-express-graphics-card-zt-p10810g-10p-gx-10p-zt.html ;) have been told the card is now end of line and cant be ordered any more.

They are suggesting RTX 2080 with 8gb ram ( https://www.overclockers.co.uk/inno3d-geforce-rtx-2080-twin-x2-8192mb-gddr6-pci-express-graphics-card-gx-077-in.html )

Is the 2080 the better option. Will 8GB be adequate for most scenes or will I find myself wanting more? Can anyone offer some advice here because it's holding up the build and I'm really not sure what to do.

 

Thank you.

    I'm not an expert on video cards, but I would have thought 8gb was more than adequate. My laptop itself has 16gb ram, but from what I can tell my mid-range card only has 2gb and I've never had any problems rendering with it.

    It really depends on wat sort of scene you render  -8GB might be enough, or even 11GB (not 12, on a 1080Ti) might not be enough. Don't forget that there are ways to lighten the load, by reducing texture sizes or stripping out undded effects or reducing SubD levels, to get more into the GPU's RAM.

    I have a 1080ti and have only occasionally exceeded the 11Gb. When I've checked my VRAM usage included driving my 4k monitor I'm usually well under 8Gb so an 8Gb card should work for most things excpt battle scenes or scenes with very high subD levels. Even then Scene Optimizer can trim down the textures of stuff not in the viewport.

    Thanks for the reply’s all.

    I’ve been a LONG time user of Poser and only just recently started using daz3d and the genesis 8 models. I’m only a hobbyist and not doing any professional work. A maximum scene will probably contain a maximum of 6 characters and something like a stonemason scene. Most work will probably contain a couple of figures.

    I’ve read the 2080 cards are only supported by the beta release of daz, has this changed. A newer card should be better for future use (I imagine) but what is the current state of such cards?

    Thanks again.

    shame you can't use a proper sized 1080ti, instead of a mini as Overclockertill have some in stock.

    Newegg.ca (Canadian store) still stocks the 1080ti with 11gb of memory.

    As does Newegg.com (USA)

    At those prices why on Earth would you buy one? Those are the same prices as 2080ti's.

    When people say the cards are sold out they usually mean they are sold out at or near MSRP. We're not saying that some disreputable seller on Amazon or Newegg or eBay hasn't held back stock at jacked up prices and still has them at 50% over MSRP.

    Thanks for the alternatives but cost is an issue at this point after paying out for the new machine.

     

    Can anyone answer whether their 2080 alternative from my original post is going to be any good and are the 2080 cards supported yet?

     

    thanks again.

    The 2080 is supported. You just need to get the 4.11 beta

    I'm actually in the exact same boat as you Keowrath.  I used Poser for years before getting a new comp/GPU a month ago and moving to Daz3d.  So I have a RTX2080 with 8 GB ram and it works fine for the most part.  The issues I do run into are these:

    1:  When rendering with 16k HDRI I find that sometimes memory will get eaten up and if it exceeds 8 GB then rendering will fall back to the CPU which is much slower.  However, this might be due to the fact that I leave old renders open which (as of a few minutes ago) I just found out takes up memory.  I have found that quitting and reopening the scene right before rendering will fix those problems though.  Note that I do render quite large scenes (9000x9000).

    2:  You will need to use the beta, which has crashed 2-3 times on me, and Daz3d does not have an autosave function like Poser does. 

    Daz3d takes some getting used to, but once you get the hang of it, it's a lot better than Poser.  Going back, I am wondering if maybe I should've gone with the 2080 Ti with the 11 GB memory, but then I go look at the price tag and decide against it.

    The "release" version of DS crashes about as frequently as the beta IME.

    Not sure what HDRI's you're using but most of the ones I've found have lower sized ones available. You might also want to look into the Scene Optimizer script avaialble here in the Daz shop.

    I did see that, but so I'm curious if that would make a difference because a lot of the time I have just one G8 figure and the 16k HDRI in the scene.  I watch GPUz and it tells me that I'm using up a pretty large chunk of the GPU ram, 6-7 GB of it.  Would the SO be able to optimize it if that one huge HDRI is taking up most of the memory?  (I'm assuming that that's what's taking most of it up?)

    Thanks all for the reply’s,

    Ive decided to go ahead with the 2080. 

     

    Thank you again.

    It would shrink the HDRI and the G8F textures which often have some really huge textures that aren't needed.

    Don't use the 2080 as your primary display. Get a lower-grade GPU for that, or use the motherboard display out. Using the rendering GPU for primary display consumes resources of the GPU that could be applied to the render, including VRAM. If you're running a 4K display, you're throwing valuable rendering resources out the window to be trendy.

    As for 1080ti prices, those are insane! The 2080ti is available direct from Nvidia for $1200. Those extra fans on those aftermarket 1080tis are not worth $100 each.

    Or if you can live with 8GB, the 1070ti is $450 direct from Nvidia, and has 2432 CUDA cores. Two of them would be $900 and give you 4864 CUDA cores (but still only 8GB VRAM). More cores means faster renders.

    However, if you're using G8, and you intend to put 6 of them in a scene, 8GB is not going to be enough to render them in Iray unless you wanted them naked and hairless.

    Poser didn't have to worry about VRAM with Firefly, but with Iray, your two primary concerns are going to be VRAM and CUDA cores. Come up short in either of those, and you're in for a very long render session.
