Native Encode still uses GPU for encoding.....

So it seems to me that in DR18 setting Encoder to Native does really nothing different than setting it to Nvidia.

System stats are showing the GPU is still doing a significant amount of work on Video Encode

It is supposed to be that way.
The difference is that Native uses the DR encoder, not the Nvidia encoder.

I am in the Free version and the GPU is used to full while CPU not, free only have Native.

And in my case much better since GPU builds ~25ºC less at maximum power than the CPU.

But this does NOT make sense. If it's the native encoder, it would be CPU based but it's not taxing the CPU at all. It's loading up the GPU for some reason.

The source clip is an h264 Zoom recording. There is nothing being done to the clip on the color page, nothing on the audio in Fairlight. All I did was trim the start/end and render.

There literally is nothing for the GPU to do here.

Using 'Studio' myself.

I'm not seeing this in Studio 18.0.3 on Windows 10 with an RTX 3060.

Using Native, the CPU gets pegged.

Using nVidia, the GPU does.

Big difference in speed, too.

Did you choose H.265?

I wasn't aware Resolve now had a "Native" option for H.265, so no I didn't.

There I see the issue.

Perhaps the Native option was prematurely added.

In Free version that only have the Native i think - i don't have Nvidia option - encoding in H.264 i have the GPU much higher than the CPU. I have simple transitions and not any more effect. It is one of the reasons that made stay in Resolve, since i am not very happy with edit page.

Please use gpuz (https://www.techpowerup.com/gpuz/) to see what Resolve does. The windows built in task manager isn't specific enough.

Dear Aglyons,

I think I have figured it out. But before I tell you, like it's been advice to you. Don't use Windwos task manager. In my opinion, task manager show wrong measurement. I use GPUZ and MSI afterbuner.

Now back to the topic

If you use in your project any kind of FX from the color tap. At the rendering Davinci resolve Studio will use only the GPU. I assume maybe it wil also happen with Fusion tap, but I don't know it for sure. I just had test with the fx on the color tap.

I hope you have help you out.
