Help for Render not using GPU!!

Hello evryone!

I have a problem that I have an Asus RTX 3060 o12G video card, but I can't use Daz Studio to render.
It only uses the CPU, which is i7 4 core, and it already spins 100%. The video card studio driver is version 526.98. I have made the settings for Daz Studio on the Nvidia control panel. Cuda Z program recognizes it. Bios all good.
Interesting that it's a plain background and character and when I do something there the GPU spins up for a few moments, but nothing when rendering. checked in the task manager.

Please help, I'm out of ideas!

If you are using Task Manager where are you looking? The default information does not catch CUDA activity - try the Performance tab in Task Manager, with More Details on, and set one of the graphs to show CUDA or Compute_0; is that showing activity? If not, what is your driver version?

How large is the scene?  If your textures are more than your video card can handle, Daz will fall back to doing 100% CPU render.  Try at first with a simple scene: 1 model, simple 2K HDRI background.

Also, check your render settings and make sure that your GPU is selected for photoreal mode and interactive mode

In fact, I can't check the cuda, but I recently put the RTX 3060 in the computer and I don't see that it has a shorter completion time. And the processor is bumping along at a high performance. I can't find anything in task manager that checks the cuda. if you know something that can be used to check this, thank you. The card is running the latest version and I'm sure it's fine, I just have a feeling it's not being used, it had a GTX 960 in it before and I just need to see if it has a shorter render time.

If you don't have CUDA listed try one of the Compute options

What version of Daz Studio are you running? If you are using an old version of Daz Studio, it may be older than what works with a 3060. I see that you had a 960, so if you have not updated Daz Studio in a long time, this may be your problem.

You can also try installing the Daz Studio Beta and see if it work with that.

On my laptop, running Studio drivers, i had instances of no activity at all during render, which likely meant, the GPU was being used. (Rendering the exact same scene, forcing either of GPU/CPU, plus some random/combined settings.)

So the performance tab can not always display the actual values. Possibly there is or has been a driver update, but i have not gone in-depth on that, also due to CPU and GPU pretty much delivering the same performance (on a specific test scene, which is not representative of all the things out there, seconds difference on something like 3 minutes render time).
