Please forgive the compound nature of this question. I suspect the problems may be related.
I recently upgraded my Dual Xeon to Win10 from 7.
Not sure I am seeing the render speeds I need.
With no priority selected, you will see that I have a very strange activity spread between my GPUs. Really only 1 GPU at work. This is for both the Preview and the Render.
When the Preview Render finishes, it looks correct, and denoised (denoise not shown as I wanted to capture the GPU information in action).
Why is there almost no GPU activity on 3 of my GPUs? (see lower image)
Separately, and this may be a bug: When Rendering (not preview) the message "Please enable denoise in current camera imager first!" flashes. I do have it enabled in the Spectral AI Denoiser panel..(see upper image).
Then, even though the lighting starts out correctly, it seems the HDRI drops out.
Thank you for advice and help,
