But still not cheap, which was my point - that the saving from a lesser GPU chip might not lead to a low enough price to make the low-end chip/high memory boards really affordable..
Well my point was that it doesn't seem to be VRAM prices that keeps NVidia from adding more VRAM to their cards. The Titan X for example has 12 GB DDR5 and costs almost £300 more than the AMD Radeon card with 32 GB DDR5. Apart from 20 GB more RAM the AMD card also seems to have better specs than the NVidia card in most contexts, according to this page:
https://www.game-debate.com/gpu/index.php?gid=3930&gid2=2492&compare=radeon-pro-duo-32gb-vs-geforce-gtx-titan-x
So, diving a little deeper in to this. The RTX 2080 ti has done a great job of reducing my render times, and I'm happy with the results.
However, there are a few things that I've observed along the way.
#1 While my render times have decreased dramatically from 8+ hours to ~45 minutes, I believe I system was doing so while the system was operating my graphics card bus at x8 bandwidth (meaning at half it's capacity) vs. it's x16 full bandwidth mode, as I had other devices (Wi-Fi & SATA Controller) also installed on the PCIe bus. Along with, what I already knew was gonna happen, the Intel i7 3770 Quad-Core (3rd gen) bottlenecking the performance, along with the DDR3 1666 MHz RAM.
If you're experiencing performance issues, please check to make sure other device are not causing your PCIe lanes to switch modes like mine were.
Tomorrow, I will be experimenting with a new rig:
AMD Ryzen 3900x 12-core 24 thread, PCIe 4.0 Support (dedicated full-time x16 PCIe Interface)
DDR4 3200 MHz - 32GB
MSI AM4 X570 PCIe 4.0 - Dedicated Full-Time x16 PCIe Slot - plus an additional x16 / x8 / x4, and x1 PCIe Slots (PCI Bus) - which will be used for my Wi-Fi & SATA Controller.
If anyone is interested in the results, let me know, as (with the exception of the 2080 ti) this build is pretty cheap, but the performance should be outstanding.
So, Nvidia 442.19 Studio Driver is out. Getting Anxiety over it already. Not looking forward to having to install it if it f's everything up. lol
Will update on the results.
I've just installed it, no problems so far (GTX 1070, DS 4.12.1.55 public beta).
Thank you for that information. Same configuration that I have.
Well, still dropping to CPU sometimes if modifying textures/shaders in Iray preview mode (small scene, Allow CPU Fallback unchecked (what does that do, actually?)), but I don't know if that's a DS or a driver problem.
No problems so far. (RTX 2080 Ti, DS 4.12.1.55)
Yeah, the texture thing is still there for me too. I've just come to terms with that... lol
The CPU Fallback option determnes what happens when the GPU(s) fail - see https://www.daz3d.com/forums/discussion/comment/5274781/#Comment_5274781 (note that chnaging the setting requires a restart).
OK, thanks!
I have a 1080ti and often render more than 2 people and scenery in one render.
. If you do the seperate render correctly the shadows shouldn't be a problem, it does require some pre thinking, but you can also do spot renders rather than render the whole image.
I am trying to digest this thread since I have had issues with studio since I bought a new computer with a GTX 2080 Super. It has 8 gigs of ram. My computer has 32 gigs of ram, it seems rendering with the super does not work nearly as well as it should.
Scene optimizer does solve the problem but I am at a loss as to why this is all needed to render stuff I could easily render on my previous computer with less hardware?
I continue to have the same issue with D|S dropping to CPU for the same reason. This has been going on for me for some time now. I keep hoping a new Nvidia driver will rectify the issue, but no joy.
WSince everyone does not have the issue a driver update ios very unlikely to fix the issue. You need to identify why it is happening. More than likely you're running out of VRAM and need to optimize.
Im personally fed up with iray and RTX, i have a 2080t, i have the latest beta with the switch that prevents dropping to CPU. Yes it does not drop to CPU anymore, it just stops rendering. Wow.. great fix.
I'm one of the lucky ones that i still have daz 4.11, i think that was the last version that came without RTX accelertion for the 20 series of cards. That version of studio is rock solid, I could be working for an hour, multiple renderes and it will not crash. Now the latest beta, i will render one scene, it renders fine. i will then rotate the model 90 degrees and it will crash, i can not get more than 2 renders out of studio without having to restart it. My renders are super simple, one figure, no clothes, no hair. no props or scenery. render size 2500 x 2500. and it's not running out of memory, it's stops rendering becuase of an illegal access to memory.
I've tested Octane which also has RTX and it's also rock solid.
Just adding to the rest of the voices that I also encounter this behaviour since I updated my Nvidia Driver and the latest 4.12 (not beta) for the 1060 6GB... There is definitely something weird going on. It tends to drop to CPU much much quicker than previously, and the noise filter just plainly stops working after one render.
The switch has nothing to do with stopping the GPU from runnng out of memory, it is there because some users wanted it so that a failed GPU render would stop, allowing them to review the scene or take other steps, rather than launching a CPU render that they didn't want.
You are closing the previous render windows? Dropping the GPU (it isn't correct to describe that as a crash) for such a scene on a 2080Ti is surprising - I generally do only 1,000 pixel sqaure images right now and am able to do multiple renders in succession. If you have a scene that reliably does this please attach it to a Techncial Support ticket.
The Radeon Pro Duo, you link to, is a dual GPU solution. The usable ram is only 16GB/gpu.
It's also GDDR5 as opposed to GDDR6.
It' slower ram, 1.7GHZ compared to 14GHZ.
Apples and oranges.
Hi everyone, I render a lot. I mean hours upon hours on a daily basis and would like to contribute to this thread with my scenario.
Firstly, my rig.
Nvidia Driver 418.81 or 430.86 - either or give me the same results.
i5-8600K @ 4.30 GHZ / 100% Usage Temp 52c (Liquid Cooled)
32GB Trident Z RBG 4 x 8GB Stix (2400 Mhz)
EVGA GTX 1080 Ti SC2 (No changes made to EVGA's settings) 100% Usage Temp 55c
EVGA GTX 1080 SC (No changes made to EVGA's settings) 100% Usage Temp 47c
EVO SSD 1TB Windows 8.1 Pro
EVO SSD 250GB (Daz Studio 4.11.0.383 PRO runs off of here)
HDD 7500 RPM 2TB (Daz content here)
Scenario A: Five fully clothed G8s with hair - Iray preview window via Daz 4.11.0.383 with an HDRI 4096 x 2048 and one linear light.
I can sit here and run that scene for hours in iray preview and nothing goes wrong. Of course rendering normally at 5k x 5k at 95% convergence is fine as well. No fallbacks, nothing.
Scenario B: Five fully clothed G8s with hair - Iray preview window via Daz 4.12.1.55 or Daz 4.12.1.40 with an HDRI 4096 X 2048 and one linear light.
The moment I move that camera or perspective or change anything BOOM - fall back to CPU. That of course is when I am iray previewing so to speak. Normal rendering at 5k x 5k 95% convergence does its job via the GPUs just fine - that is if I didn't fall back first.
Hopefully any of this helps. As a PA here I just keep to working via Daz 4.11.0.383 and have a happy life doing so. The moment I step foot in any other Daz above that version...game over.
Anyway even with the switch turned on, you need to restart Daz Studio because you can't render again, so this fix is not helpful.
To whom? The people who wanted the feature will presumably run with it always on. You apparently aren't one of them, so it is not a useful feature to you but it is to others.
I will definitely run it on 100% of the time. I very much never want the CPU used in renders. If the scene is too big for my 1080ti I don't want to struggle through the lag of a cPU render to shut things down.
Exact same problems like the person above me describes. I am having success with Daz Studio 4.12.0 and the moment I updated to 4.12.1 all hell broke lose and GPU to CPU fallback happens near instantly on a SINGLE FIGURE with nothing else in the scene. GTX 1080 Ti here.
For me with the 2080ti it happens on the second or thrid render. As stated a few posts above, 1 single g8 figure, no hair, no clothes, but the image size is 2500 x 2500 pixels, and i do close render window when complete. Not sure what else to do, it's not running out of memory, because i have more than enough, i can;t email my scene, because it's does not always happen. it is not consitent, it might happen on the second render or it might take place on the fifith. But alway it's an illegal access to memory.

That looks like the memory leak. Are you tracking your VRAM usage in GPU-Z?
Yep I have done that. However if you have reflections then the missing characters will affect the look of the rendering. Ultra HDRI renders appear to be a lot faster than ones with a sun light.
You can set the affinity of your CPU cores via Task Manager. I have a 10 core / 20 thread I9 CPU and usually remove 2 threads from DAZ when rendering. I actually prefer CPU rendering with IRAY. Because I can free up 2 threads and use the computer while it is rendering in the background. With GPU rendering the computer is not as usable while it is rendering.
I had this Problem as well. The Asus 2070 nvidia I have was set to a bit of an overclock which caused it to drop to CPU. I down clocked it using the MSI Afterburner software and now it work great, I just had to turn the GPU speed down and set it o default. You may want to play with the memory clock as well to fine tune, I havent had time to do that yet.
Iray looks great but it depends on what you are trying to create. I have a new computer a alienware area 51 r7 with a 2950x amd threadripper 16cores 32threads and it just kills 3delight renders. I do Iray just for main charater and composite inside of Gimp or Photoshop. I also found that if you render the main character in both 3delight and Iray and merge them both you don't have to worry about fireflies that seem to be just a fact of life with Iray. If you render with differnt degrees of light and exposure you can also with photoshop create a fake hdri which looks even better!!!! Oh on a side note> If you have one of these Alienware area 51 r7 threadripper systems you need to get rid of the crappy small 120mm water cooler and get the (bequiet dark rock pro tr4 air cooler) it keeps my render temps under control unlike the water cooler used by alienware. I highly recommend this air cooling solution.
I have used daz studio since it's inception (and paid for it too). It's always been a dog when rendering animations. The makers have always insisted that Daz was not designed for animation but when you include it as a feature you expect it to work (and be improved as users demand it). There seems to be an inheirent problem with the program realeasing memory, or clearing it's cache. More and more people are into animation these days if only to get multiple shots from different angles and use the stills. I have used many other programs for rendering animations that have no problems with large or complex files, and when you see a program like Unreal 5, that can render 3D in realtime at 60fps plus, it makes you wonder what Daz programmers are missing?
I am moving from Daz as fast as I can to Ureal 5 to do my rendering from now on.
