Server Version#:latest
Player Version#:latest
I have both of these in my server. I have plex pass. I’m rotted cause I went from a gtx 970 to the 1060. Thinking it would help the transcoder. But no.
My cpu is always pegged around 50-100 percent. And gpu is like 5 percent. Tested with unlocked drivers
People seem to say this gpu can handle 2 streams of 4k. Yeah… how. I can’t get it to barely do any transcoding on gpu.
Any ideas what’s going on?
Are you transcoding 4K HDR media?
Do you have tonemapping enabled?
On Windows based systems, Plex does not support tonemapping with Nvidia GPUs, so it hits your CPU. See support article linked below.
Turn off tonemapping (Transcoder settings). Check CPU & GPU utilization when transcoding 4K HDR media. The colors will be off, but you should see the GPU used.
Monitor playback via Plex Dashboard → Now Playing. It will show you if hardware acceleration is used for the decode and/or encode portions of the transcode.
You can also pull your server log files. Lines containing MDE: tell why something is transcoding. Lines with TPU: show which decoder/encoder is used. You can also filter the console for TPU:.
Hardware transcoding on my server. It is running Linux and using Intel graphics, so decoder / encoder is vaapi. On Windows you would see NVDEC and NVENC when not using tonemapping. I’m not sure what you will see when using tonemapping. I’m not set up to replicate such a situation.
