(SOLVED)My daz3d started to render really slow for no reason.

I don't know what happedened. Everything was normal and how it should be and for some reason my daz3d started to render same scenes incredibly slow. It takes 4-5 mins to render gen8 female character with blank background in 720p or it takes to render 1% for 20 mins for an interior scene with objects. Anyone knows the reason or are there anyone who has the same issue?

Have you updated Daz Studio (assuming that is what you mean)? Whata re your hardware specifications, and - if you have an nVidia GPU - what is your driver version?
Yes I have latest daz3d version and my nvidia driver is last verison too. I have one rtx2080ti and one gtx 970. Like I said everything was fine couple of days ago but for some reason it takes too much time.
If it was me, I'd go into Task Manager (assuming you're on W10) and see what the GPU's are doing. Specifically, are they running the Iray CUDA render engine as expected, or did something happen and maybe the CPU is doing it (you can watch the GPU VRAM usage by process in Task Manager, as well as total). Also, check if maybe some other processes are using the GPU simultaneously and taking the VRAM? Also check the D|S log file to see what happened during the render.
Or maybe you changed a render setting without realizing it?
Note that to see what the cards are doing you would need to go to the performance tab of Task Manager, which requires having More details enabled, and set one of the GPU graphs to CUDA (or Compute_0 if CUDA isn't there).
I looked up to task manager and changed my 2080ti to cuda and 970 to compute_0, task manager shows they are 100% working. And gpu-z shows they are 100% working too. But after my render is finished and I close daz studio, if I look to task manager it still shows CUDA as 100%. Does that mean some other thing is using my cuda?
You can go into the Processes tab in Task Manager, and along the top you'll see "CPU", etc., columns. Right click on any one of those and select anything that says "GPU", and it will add GPU usage columns showing how much each process is using. That way you can see who's hoarding your GPU.
I did what you told me to do and it shows 0% on daz studio and it's peak without daz is 1%-2% max. Looks like nothing hoards my gpu. What should I do I'm stuck really :/
You mentioned that after you close DAZ your GPU usage is still 100%, right? If that's the case, you can click on any of the GPU-related process columns to sort the processes by whats using the most GPU resources. If something really is using your GPU behind your back it should pop to the top of the column.
What I meant by that was CUDA usage. In task manager's performance tab if I change 3D to CUDA under my selected GPU, it's always 100%. But in the Processes tab in Task Manager my GPU usage is always like 1%-2% and Daz studio never uses my gpu even though I have selected only my GPUs in advanced render settings.
So the CUDA render engine is still 100% after you close DAZ Studio? I've had it take some time to shut down (like a minute or so), but usually it's pretty quick.
Otherwise, it sounds like maybe GTX 970 started running out of VRAM and rendering dropped to only the RTX card, but I doubt losing the GTX 970 would matter very much.
Did you check the log file as I suggested? Maybe something changed with your scene file you weren't aware of?
Which version of Windows are you using? I have only GPU and GPU Engine, nothing that will show CUDA activity.
I think I found the reason. Log file says: Iray [WARNING] - IRAY:RENDER :: 1.0 IRAY rend warn : There is no CUDA-capable GPU available to the iray photoreal renderer. And:Iray [WARNING] - IRAY:RENDER :: 1.0 IRAY rend warn : iray photoreal rendering is disabled.
I think this is because my something hoards my CUDA . But how am I supposed to find what it is? Or is this the reason at all?
Win 10
So it's not finding either of your GPU's, but it did previously? You might go to W10 Security & Maintenance/Maintenance/Reliability History and it will show you, for the past few weeks, what happend on your PC, including errors and warnings and driver installs, etc.
Check that and see if anything happened coincident with your renders suddenly slowing down.
What is your driver version - right-click on desktop>nVidia Control Panel?
If you're asking my CUDA version it's 11.2.152
There are some critical events but they are not related to daz3d or any graphical stuff.
I'm wondering if the RTX doesn't play nice with the much older GTX 970. Maybe try disabling the 970 and see if that helps. If it was me I'd go in and pull the 970 out altogether.
No, I was asking your driver version - assuming you are on Windows.
Every so often a figure will get a morph applied that will suddenly run my machine out of RAM. From almost nothing to overloaded. You wouldn't see this on a fancy rig with an NVidia card as easily, but on my Mac mini you certainly do. Sometimes, having superhardware covers up problems. I just start the figure over, since you can't delete morphs (except for Discobob amd his Fit Control, who has figured it out)
Sorry for late replies had a lot of work to do. It's 461.72.
Didn't change anything :(
Did the installation of that driver correspond with the problem you're having? Like I said you can check in the Security & Maintenance/Reliability History chart that tells you day by day what happened on your machine.
It wouldn't be the first time that a new NVIDIA driver caused some goofiness
And was the driver downloaded from https://www.nvidia.com/Download/index.aspx or was it updated by Windows 10 (Big NoNo...)?
Only thing I can find related to nvidia is NGX updater stopped working yesterday and two days ago. But I don't know what that is and how it could effected.
"Updater" sounds ominous... Go to https://www.nvidia.com/Download/index.aspx and download drivers and install them manually, that is just about the only reliable source of Nvidia drivers.
Guys I solved the problem. It was a mining virus all along that used my cuda. I enabled app & browser control from windows defender and ran a search through my pc, found a virus named Gminer. Removed it and my CUDA usage dropped to 0 simultaniously. Tried to do some rendering from daz and yeah, everything looks normal. Thanks for everything guys. I appreciate truly :)
