Hi
I hope that somebody can help me.
Just got an additional W10 PC with RTX 2080-Ti graphic card. PC's are identical
I have made exact same setting on the new PC
Both PC's are running DAZ Studio 4.12.0 Pro Edition (64-bit) Publick build
Both PC's have latest GForce driver 442.19
Pc's share library from a third computer.
The old PC has perfect result where the new one render with some kind of distortion or gritty.
Various benchmark programs gives the same result for the graphic cards.
Anyone who knows where to search for the problem?
A longer rendering time doesn't change the result.

Are you 100% sure the render settings are identical? The first image is less converged than the second so I suspect that the second had a denoiser run on it.
The image with noise is likely the more accurate one; characters, that use the denoiser often look like the one you state to be perfect, which actually looks fake to me. In effect, it's too perfect. :)
Thanks for your answers.
How do I control the "denoiser" Doesn’t seems to be a parameter I can find
Yes and no - my problem is that I can’t find any different, so that’s why I ask for help. Quite sure that some minor issue cause the render problem. You’re probably right with the denouser but no clue where to search.
Thanks again
Render Settings->Filtering->Post Denoiser Available->Post Denoiser Enable
Thanks for your answer but realized that it's disabled on all my machines. I tried to enable it but with no effect.
What I haven't mentioned - I have another machine with Nvidia 1070 8 MB and that is rendering perfect too.
There is fairly obviously some render setting different between the two. You're going to have to compare all of them until you find which one it is.
Can you compare the render logs (and maybe post here?) so check the little render window and push the history/details button.
Thanks sure
Will make 2 similar renders and post it - please hold :-)
I only bring it up because you mention it is a new PC.
But double check you NVIDIA drivers as well. If windows does an update, it seems to overwrite the NVIDIA drivers. So if you set everything up and then went through a windows update, you may not have the correct NVIDIA driver.
Checked the log, it seems your GPU isn't initialized at all. So Daz Studio/Iray can't find the GPU. So first check if Daz Studio, in preferences I believe, your card is seen at all.
You also need to check the Nvidia control panel to verify that DS is allowed to use the card.
Definitely verify that the driver is new and disable Windows Update from installing any drivers.
Hi all
Thanks for your help. Problem solved.
It was not NVIDIA, but DAZ studio. It seems that very latest version has problems with rtx 2080-TI. I found an earlier version and installed it, and now it’s working.
Again thanks for your help
Glad to hear you got it running!
Plenty of people use 4.12 with 2080ti's. That was not the issue.
I have dual 2080 Ti with DAZ 4.12 and do not have this issue.
Noise can be cause by a couple of things. Most often it's due to inadequate light in the scene. Increase the environment or spotlight brightness. Another is if you're using emitters versus spotlights. Another is if you're using built-in lamps but NOT the Spotlight. Another is if there is reflective surfaces and you're catching bounced rays or if Caustics are enabled. Another is if you have lower convergence settings. Another is CPU vs GPU, which I think someone pointed out in your logs. Just a few guesses.
From your log file:
2020-02-18 14:34:59.102 Iray [INFO] - IRAY:RENDER :: 1.0 IRAY rend info : CPU: using 8 cores for rendering
In fact that's not the case. I thought that it was solve but new renders showed the problem again. I have 2 similar machines sharing my work. 2 identical machines rendering the same material. Old machine is perfect - new one switch to CPU. For the new machine I increased the power supply with no result - increased memory to 32GB with no result. I have been through all the settings and they are identical. Been through almost every forum and haven't found the magic trick yet. When I read various forums it seems very random. What happen - after few sec/minutes it switch to use the CPU. If I render small job's it's not an issue and continue to render with GPU's but as soon as the job is fairly larger it switches to CPU. It seems to load my power supply with almost 100 % on the new machine - with the old one I have no issues. I have tried various versions of DAZ Studio - used NVidia studio driver and game drivers. Switch back to previous NVidia drivers with same result. I can use the machine but rendering time needs to be 100 to 150 % longer because it switch to CPU - that means significant slower than my third machine with 1070-Ti running older version of DAZ.
My last setting gives me an error telling that there is errors using GPU and Optix no longer is supported - even when it's not switch on.
Any idea what it could be? - I ran out of ideas.
What precisely are the specs of the system.
CPU, motherboard, PSU, storage systems, even the cooling and the case. If it is a prebuilt, by who? Since you got it have you updated all drivers? Have you run DDU and then installed the newest Nvidia driver?
Most likely something is misconfigured in the system.
Less likely the 2080ti is not good and needs to be RMA'd.
Either way contact the seller and explain your issue. Since they sold you both machines they should be able to figure out what's the difference.
Thanks for your answer. The problem is that the 2080 -Ti seems to work and for me it look's like a software issue. They'll probably just say that the machine works as expected. I'll try make some more benchmark on the 2080 -Ti to see if something looks different.
Thanks for your help
Go to Render Settings > Advanced > Hardware > Photoreal Mode > Devices and un-check your 2080Ti in the list. Then immediately re-check it and start a test render. There's a good chance your GPU may now suddenly start being used.
It's a shot in the dark, but in comparing the two logs, one difference I saw was Optix error.
For the 2080-ti machine, don't check the box.
I don't know why it would make a difference, but I do recall another poster having a problem that unchecking the box solved. I seem to recall that Optix is not required for new 2xxx cards, but don't depend on me for that.
Another thing, I'm assuming once the render drops to CPU, and you try something else, you are restarting Daz over again before trying another render?
There is another thread that explains it better, but I have experienced it as well with a 2080ti, once you drop to CPU, (for me it is usually a scene was too big), it will continue to use CPU only, unless you restart Daz.
Thanks for your feedback
I never use Optix so that's not the case. Tried almost everything and I always shut down and restart. Thanks for your shot :-)
Weird - un-check and check - for 10 minutes it was working but then switched back to CPU
