Hardware acceleration/transcoding not using Nvidia card

Plex Media Server
1

Server Version#: 1.26.0.5715
Player Version#: 9.0.6.31998

I am struggling to get my Nvidia GTX 670 card to handle the transcoding of video streams. when video plays and requires the transcoding the CPU spikes at 100% and video will buffer.

Plex Media server is running on Ubuntu desktop 20.04.4

daniel@plex:~$ lspci -k | grep -EA3 ‘VGA|3D|Display’
01:00.0 VGA compatible controller: NVIDIA Corporation GK104 [GeForce GTX 670] (rev a1)
Subsystem: eVga.com. Corp. GK104 [GeForce GTX 670]
Kernel driver in use: nouveau
Kernel modules: nvidiafb, nouveau

I know it currently says Nouveau, and I believe that is not going to work for decoding and encoding but i have recently tried all I could to get it going with the recommended drivers for nvidia GTX 670, which was the 470. tried the -server variation and non server

read someone elses post and they had the logs pointed out to them and found the TPU Hardware not found error which i also have/had;
DEBUG - [Transcode/108c401456c32400-com-plexapp-android] TPU: hardware transcoding: enabled, but no hardware decode accelerator found

Could someone please help me figure out how to get working?

The problem you face is because there is no Decode/Encode support in the GTX 670

Please refer to:

We’ve found the P2200 Quadro and GT1050 TI to be good cards for PMS use.

From there, the version 510 drivers work well.

Thanks. this would be a good link to provide on the hardware transcoding plex help article in the area that talks about using a nvidia gcard.
