I’ve been running Plex fine but have not had any 4k videos as I know the hardware can’t handle it
Bought a NVIDIA Quadro P2200 and installed it in the server today
Plex now shows videos at (hw) transcoding but it doesn’t seem to be putting any load on the GPU at all
Attempting to play/transcode a 4k HEVC movie buffers for about a minute, plays 20 seconds, then has to buffer again. Neither the GPU or CPU show a spike in usage at all in these times
What client are you playing with? Some support hevc so it may not need an actual transcode. The buffering could be due to your network and not the transcoding.
Best way is to reproduce the issue and provide your PMS logs. Providing the XML for the video you used also helps.
Mar 13, 2021 22:17:24.526 [9176] DEBUG - [Transcode] TPU: hardware transcoding: final decoder: nvdec, final encoder: nvenc
According to your log. PMS found that your GPU is supported and can use it. However, you didn’t provide your entire log so I can’t tell if it actually did work or not. Please just attach the entire log file.
The GPU does seem to get a small amount of use when I start watching, but nowhere near what I get when I start a normal x264 stream that it has to transcode
Something odd is going on. It’s trying to use a really odd resolution. My guess is that the GPU doesn’t like that resolution so it fails and then reverts back to CPU, which matched your screenshots. I’ll have to check with the devs why it’s using that resolution.
If I try to transcode to play on my phone it shows this instead

No, but we did find a bug with transcoding HDR and some Intel hardware. It’s possible that is the issue you are having. The fix for that isn’t available yet. Can you confirm what type of CPU you have?
In the one example I saw in your log from before, something was telling the hardware to use a strange resolution. I could not determine what cause that. If you have more logs with the hardware failing, I can check for more information.
