(7.0.20210.12505, 28.07.2020) When rendering is done, I select the Intel Denoiser. [image] Once this was checked, the CPU load cranks up. It stays as it is, even if the Render window is closed. [image] Only closing and restarting Rhino helps. Apart from this, the Denoiser is a very good thing…

All fixed in (7.0.20238.17095, 25.08.2020). Great!

@nathanletwory The GPU usage is clear to me. I talk about the CPU usage. The same CPU usage is seen in V7 when using Raytraced in the viewport. Please try Raytraced in V6. And view CPU load. Then see in V7. V6 uses “no” CPU, V7 uses “all” CPU.

I’ll check in a few days when back at work from vacation., Actually, I was confusing the right-hand side graph for the CPU, but that is the CUDA usage, mobile phone display was a bit too small to properly see :slight_smile: . There is indeed some CPU usage, and I’m going to guess that it is related…

Slight…no that’s not slight. Try Raytraced in V7 and zoom in and out while Cycles works. I see up to 100% CPU load on a 12 core CPU. That is quite different in V6. It is dramatic… [image]

I am seeing around 50% CPU load when Raytraced is running here too. V7 on a dual 6 core Xeon (=total of 12 cores and 24 threads) Intel denoiser turned on in render settings. When in Rendered mode and Rhino idle in the background the CPU load is 6%. When I turn off Rhino it drops to 2%. That is …

I’m still going to guestimate it has to do with the changes introduced for the post effect pipeline.

There were 2 issues: CPU load after denoise This is fixed in the current WIP. CPU load while Cycles works Still there. I found out that the CPU load increases when you zoom out.

(7.0.20231.16005, 18.08.2020) CPU load unchanged…

Probably because I haven’t had the chance to investigate yet, been back from vacation only for 4 (work) days.
