Renders Only Using CPU

in Technical Help (nuts n bolts)

I have an i9 9900k, 64 Gigs of Ram and an RTX 2080. 
My GPU Drivers are up-to-date and I'm using the latest version of Daz, 4.11 (Post Beta).
I have USE CPU turned off and USE GPU on but no matter what the settings, my renders ALWAYS only use my CPU. Which hovers around 18% in the Task Manager.
I don't know what to do and the forums/every website I've seen doesn't help.
This same thing was happening when I was using GTX 980's SLI and 32 Gigs of Ram so I'm pretty sure it's a Daz setting or a Daz thing and not my PC.

If someone could help me utilize the power of my GPU that would be GREATLY appreciated. I feel like Daz is extremely poorly optimized but maybe I'm just an idiot and have something turned off somewhere.

    How are you seeing that the GPU is not being used? I suspect you are using Task Manager which, by default, does not show Iray use - if you go to the Performance tab and set one of the graphs to Compute_0 or CUDA (depending on which you have) I think you will see that the GPU is being used - othewise the CPU would be getting close to 100% usage.

    I have been using 4.12 Beta and now 4.12 on CPU only with only the occasional lock up, usually because it is using all my 16 GB of memory when doing a big scene. Today I was running a render on 4.12 and I started 4.12 Beta at the same time to do a test render on something else and I could still use my laptop email and internet.

    Yea I used Task Manager. GPU sits at 0% while CPU is about 15-18%.

     

    My render times are good and I can even play games on Max settings while rendering but when I saw GPU wasn’t being used I was worried. I’ll check the processes tab.

     

    I wish I could utilize more of my computers power for rendering. I built this rig for rendering and it’s as if I’m using a quarter of its capability.

    You are, I'm pretty sure, using the full capacity (that Iray needs) of the GPU.

    Didn't realise there was a min driver version for 4.12, updating mine now, going from 430.64 to 436.30, hope it works as I can really do without burning out my CPU and fan two weeks after I bought the bloody thing.

    I think you will be successful after that driver update. The required version is documented in the DS 4.12 Highlights thread. There is a lot of information there.

    GPU-Z is a free tool that many of us use to monitor GPU usage. It is a bit more straightforward that digging through Task Manager.

    Also, HWiNFO64 is a great utility that not only shows all of your processors/threads individually, it also displays their utilized memory in real-time.  It's great for monitoring your memory consumption and you can instantly see when your GPU memory has been exceeded.
