RE: perf. RTX 3060 ti slower than GTX 1070 - NVEnc - mimile - 06.01.2022
I just tested in multi GPU, the GTX 1070 is the GPU0 and RTX 3060ti is GPU1.
when I run the encoding, it runs on GPU 1 with the same performance as a single GPU (with RTX of course)
this is my last log encoding :

How to share the whole decoding chain, how and where do I get the info?
RE: perf. RTX 3060 ti slower than GTX 1070 - NVEnc - Selur - 06.01.2022
Easiest way: create a debug output (you should have read the sticky and know how to do it)
More complicated:
a. check the sub jobs while disabling 'Minimize job command lines' and copy the _video subjob calls.
b. if you use Vapoursynth or Avisynth copy the scripts that are shown in the script preview

RE: perf. RTX 3060 ti slower than GTX 1070 - NVEnc - Dan64 - 06.01.2022
The speed figures that I provided are for standard 1080p movies.
Of course the encoding speed will decrease when are encoded Ultra-HD movies.
To give an example these are my encoding speed with my RTX 3060 obtained with Ultra-HD movies
Movie size: 4096x1744 -> speed: 104 fps
Movie size: 3840x2160 -> speed: 93 fps
I strongly suggest you, if you want to get the max speed to let NVenc to fully manage the video tasks.
To do that you must enable the checkbox "NVEnc->Harwdare->Only use encoder"

I don't use Vapoursynth or Avisynth
I know that the size of the video decreases the fps for encoding, which I don't understand is why the RTX is slower than the GTX with exactly the same settings.

Hybrid is using ffmpeg to send the video frames to NVenc. It is difficult to say if the problem is due to ffmpeg or to NVEnc.
Please try to perform the test again with the 2 cards, with the checkbox "NVEnc->Harwdare->Only use encoder" enabled.
In this way "ffmpeg" is not used and NVEnc will be the only software involved in the encoding.

this is what I just did, by checking the box it did not change anything with the rtx

a. enable "NVEnc->Harwdare->Only use encoder" and recreate your job, changing setting without creating a new job does nothing.
(this way the video decoder chip will be used and the decoded content will directly be send to the encoder)
or
b. enable "Config->Input->Decoding->Use gpu for decoding"
(this way the video decoder chip will be used through ffmpeg and the decoded content then be processed and send to the encoder)
atm. the decoding is done with the ffmpeg software decoder (so your cpu).

RE: perf. RTX 3060 ti slower than GTX 1070 - NVEnc - mimile - 07.01.2022
I redid the test with your settings, nothing changes, the "video encoder" part is always used at 100% during encoding, the card fans also run faster, I have the impression that the RTX is restricted, is the LHR the cause? normally no...
I may have missed a parameter in windows ...
I feel like I bought an RTX for nothing ...
I will redo a last test with the gtx and send you the debug to compare
RE: perf. RTX 3060 ti slower than GTX 1070 - NVEnc - mimile - 07.01.2022
I tested with the last reset nvidia drivers, and tested with the nvidia studio (511.09) drivers, it's still the same.
I redid the test with the GTX 1070 to compare the debug file, it turns out that it is slower with the "Use gpu for decoding" option, and without it, it behaves as before.
debug with the "Use gpu for decoding" option:
https://uptobox.com/0r5i6kf0feh0
debug without the "Use gpu for decoding" option:
https://uptobox.com/o5mr38jjc0xi
I don't know what to do with the RTX 3060 Ti ... pff
