(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!

Jorgen I believe that part of the bug has been fixed. _ Andy

Regarding RH-60016 the problem is that the CPU utilization doesn’t match the gained benefit, most of the CPU cycles are actually lost to overhead (thread managementy stuff) instead of doing anything useful (copying pixel data). This is when Raytraced is otherwise rendering on the GPU. I guess that …

Yup - that part I understand…but let’s say I make things go 100% faster, but instead of using 20% of CPU, I’m using 100%…will people be happy or sad?

I don’t see faster rendering in V7… Using the whole CPU is not good, as we can’t do anything useful on the PC when a single Rhino instance eats all the power. We select CUDA, and not CPU for reasons.

This will be fixed in the next WIP

This seems too work well now, both for the intel and the nVidia denoiser. The CPU load drops down to 0% once raytraced view is toggled off OR paused. That seems better than ever before, even without raytraced being used at all. I do see that when using the intel denoiser the CPU is constantly used …

I see the CPU is still being used even when the viewport is done calculating. Intel Denoiser is turned ON: [image]

@Holo , do you see this CPU usage also when the denoiser is off? What Rhino BETA version are you using? (First line of _SystemInfo).
