Isn't this always the case: I duly opened DAZ Studio (Beta 4.12.1.16) and switched to IRay preview. No crash to CPU. I loaded a base G8F - still no crash. I loaded another character (instead of base G8F) - still no crash. I don't understand because just a few days ago it was crashing to CPU if I looked at it sideways. Maybe my own memory is faulty and all this was happening before I removed the GTX970. Or maybe some objects/materials trigger the CPU fall-back while others don't?
The CPU fall-back is still happening when I swap shaders in and out, though. And I noticed yesterday, when rendering an image series, that there is still a jump in VRAM usage between frame one and frame two after which it remains steady. If that jump remains within my 8GB it doesn't fall back but it is getting increasingly difficult to make a scene fit within 8 GB - even after running the obligatory Scene Optimizer.
I see there's an update today so I'll try that. However, the update post only mentions RTX so I fear that any fixes for those of us with GTX cards might have been de-prioritised.
The update comes straight from NVIDIA.
Tested the new 4.12.1.40 just now with same Babina/Lingerie Robe set test. Same result as 4.12.1.16. Drop to CPU on 4th load of Lingerie Robe wearable set. Will update ticket with new log.
If you read back to the 13th of November you will see that I said that there were no problems with the latest release and beta versions of DAZstudio so long as the Nvidia drivers v431.86 were used. I have not yet tested Nvidia Studio drivers 440.28.
CPU fallback problem w/ empty scene render here.
Configuration:
Hardware
i9-9980HK CPU @ 2.40GHz, 2401 Mhz, 8 Cores
64 GByte RAM
NVIDIA GeForce RTX 2080
NVIDIA GeForce RTX 2070 (as eGPU via USB-C).
Software
Windows 10 Pro 64bit (1903 - Build # 18362.476)
DAZ Studio 4.12.1.16
NVidia Driver 441.28 DHC Studio AND 441.20 DHC Game driver
Empty scene render log (Dome based default settings) attached.
Is there any chance disabling OptiX support? I'd like to test if w/o OptiX support the problem remains.
Unfortunately the checkbox seems to have gone. And what b.t.w. is dzneuraymgr?
On the one hand, both DAZ and NVidia use Iray to market their offerings, on the other hand, they neither work together (see this NVidia forum post: https://devtalk.nvidia.com/default/topic/1067115/attn-david-hart-all-drivers-after-430-86-are-breaking-iray-for-daz-studio-4-12/?offset=10) nor they seem to pay for sufficient and professional quality engineering. Who pays is the customer, with their money (look at my hardware alone) and - much worse - lifetime.
I'm going to report this to DAZ support, too, just to make clear there's an issue to be solved.
PS: Doh, upload doesn't work. Here's the logfile content:

Weird, but at least I'm happy it*s working again.
The updated Public Beta includes an Iray update, which deals with some bug fixes.
This has me more than excited to find out more as I rely heavily on puppeteer!
Hmmm. Curious. Do i remember that right that you are on Win10?
I never get issue#1. One explanation is my OS is Win 7(64) Pro. Have come across people complaining about Win10 mem management issues for various software. Am avoiding Win 10 upgrade like the plague, so didn't read anymore in depth. Also, probably not related, but post anyway: also purged my startup setup since fnding out my X-Ray camera on start load was causing issues. Yet loading that same camera after something was in scene cause no such issue.
Issue #2 is my problem. Support seems busy so not expecting any anything really until they have anything tangible. Though acknowledgement would be nice. Hope to hear from them in next week or so.
Hope you report back. Puppeter is cat's meow! Hope they made the tab layout different so when you have lots of tabs that you don't have to cycle L-R a long time.
Will do, I'm currently doing some rendering though... I'm hoping for an official word on what was added to it.
Yes, I am on Windows 10. I don't seem to have the same VRAM problems with DAZ Studio 4.11 though but I have Optix Prime switched off for that. So what I'm doing (which confuses me no-end when it comes to remembering which version had which problem) is using 4.12 Beta as much as possible other than when it won't render a scene without falling back to CPU. Then I load it in 4.11 to render. Generally, I find 4.12 much nicer to work with in terms of Viewport operation (much smoother) and render speed (when it works).
X-Ray Camera??? Whassat???
I've been haveing the same issue for months and like I mentioned in that other thread I started. I seemed to have a tentative fix going. I'm running on close to 3 hours of solid test futzing and not one drop to CPU rendering.
loaded up the new beta 4.12.1.40 and windows 10 behind my back updated my drivers to 432.00. so I'm not sure if its a clean install or not but all three graphic cards are online. RTX 2070, and 2 GTX 960's. I can use denoise, dforce and other features. Tested them, ran them all and so far so good.
Just wanted to point out atleast one person got lucky so far, hope what I gave helps others.

Oh I give up. After reading that some of the bugs had been addressed in the new Beta, I went ahead and installed it over the previous Beta. Now I see that it has gone back to falling back to CPU on rendering an image series. It is plain to see in GPU-Z ... VRAM does not drop between frame one and frame two (it should - and it does with a working system). Instead, VRAM not only remains high but increases so that the 8GB limit is breached and, hey-presto, CPU rendering.
I am fuming now because I can't get back to the previous beta which had fall-back problems but not with the image series.
As I said above, I am experiancing NO problems with cpu fallback if I use Nvidia studio drivers v431.86
even with the latest beta of daz studio v4.12.1.40
but I notice above that somebody has reported cpu dropback with even the latest nvidia studio drivers v441.28
You guys should stop beating your head against the wall, use nvidia studio drivers v431.86 and wait until nvidia fix the problem.
I have not yet tested the latest nvidia studio drivers v441.28 myself
FYI for comparison:
Windows 10pro x64 v1903
Intel i9 9900k, nvidia rtx2080ti, 32gb ram, too many hard drives
It was happening for me with 431.86 which is why I updated them. I'm running 441.12 drivers now and, after the DAZ Studio Beta update, am back to square one with the CPU dropping out on image series renders.
I'm sorry to hear this, also sorry to sound so exhasperated, I was assuming the way I solved my own cpu fallback problems would solve it for all.
Have you tried the latest nvidia studio v441.28 drivers yet ?
or maybe there's a windows issue here too
or maybe fallback to drivers prior to nvidia 431.86
EDIT: typos as always
I've gone from everything working in 4.12.1.16 to having DAZ Studio crash to desktop as soon as it tries to render with the gpu in 4.12.1.40. I wish I could get the old beta back.
For reference:
Windows 10 Home 64-bit version 1903
NVIDIA GeForce RTX 2080 (I have tried several drivers to no effect)
Intel i7-8700k
64gb RAM
I have upgraded to the new public beta 4.1.12.0.40 from 4.1.12.0.16 and t there is one big fix:
a) When I render in DAZ Studio, DAZ Studio no longer allocates and writes to my system disk repeatedly; not freeing the allocated space such that I eventually start running out of space on my system disk until I exit DAZ Studio and reboot my laptop. So not seeing my system disk disappear every time I do a DAZ render is a big improvement.

Now what specifically does rob mean with removing dependencies on legacy support libraries?
It basically boils down to having done work necessary to allow development of the named area to move forward with the application.
Cool, thanks a ton for the speedy answer!
Happy thanksgiving to ya!
But still good to know.
That was what we originally posted about on Page 28 of this thread. My clarifying reply was 7th post from top. X-Ray camera helpful in many ways for indoor scenes, though you need to manage the planes that come with the camera.
Thanks for sharing! Have been happily using 4.12.0.86 with 441.12 driver with zero issue. If this issue drags on without a fix, and I need to get to next stage of workflow and use the beta with improvements, then will test 432.00. Got this issue originally on 4.12.1.16 with 430.39 and then tried 430.86 and issue persisted.
LOL. Am hardly banging my head on this issue.
Am using 4.12.0.86 for day long sessions without issue on 441.12.
Am posting and working on this drop to CPU issue on the side, because SOMEONE has to report these issues and try to get bug fixes in.
Oh boy, I missed the bus on both
!
I'll scan back throught the thread, thanks.
