GPU efficiency question

[protovu]

Hi Simon,
I recently upgraded my Win7 Dual Xeon to Win10. Not sure my render speed is what it should be.
When looking at the resource monitor, no activity is happening on 3 of 4 video cards.

What am I missing here?

thank you,
Rick

I'm sorry but I do not know. I don't know how well the Win10 GPU monitor tracks true performance. You may want to use a 3rd party GPU monitor. I don't have one myself. You may want to query one of the other forums. The problem won't be Carrara specific.

I also think that you should only pick one card for Denoising or Tonemapping.

I know the topic is a bit old.

It's just to confirm the windows standard GPU load monitor is (still) unreliable. See attached screenshot.
