CPU VS GPU What DAZ uses

I have a 11gb 2080ti GPU, I configured daz to use the GPU for rendering, but it is constantly using the CPU, and the common memory, it shouldn't just use the GPU and the GPU memory to render, or just pass the use the CPU when the GPU usage gets too high?

How can I force daz to use only the GPU.

    You need to set one of those graphs to CUDA (or failing that Compute_0) as task manager does not otherwise see Iray activity. However, the high CPU usage does suggest that Iray has dropped back to CPU, probably dure to memory use. Does a simple scene use the GPU?

    You can turn CPU fallback off in the Advanced tab of Render Settings, then restart DS.

    Thanks man, with the CPU and GPU, and only with the GPU I got practically the same rendering time, but only with the GPU my computer is free to perform other tasks with a good performance

    The scene I was rendering was very complex. many shadows and many objects to perform light and shadow tests.
