I have a VM running Windows Server 2022. I have thrown complete overkill specs in attempt to get this working well. 28 Cores / 128GB Ram(64GB dedicated to a RAM disk for transcoding) I have an Nvidia Quadro P4000 that I would like to offload transcoding to. From what I gathered, this should suppo…

Viewing the dashboard, does it indicate that you are using the hardware when transcoding? Perhaps it isn’t recognizing the video card and using it to transcode, so it’s happening in CPU (software). That being said, I’d TOTALLY expect a 28-core (28 core what?) CPU to be able to do software transcod…

CPU is a Xeon E5-2660. Toggling between hardware/software transcoding does show a considerable difference. The CPU is able to keep up with a single 4K HDR → 720p (high) stream. The video plays buffer free. When set to GPU, the CPU utilization drops from around 70% down to below 15%. I can also see G…

While performing some more tests, I have found that HDR Tone Mapping is the setting that is holding transcoding back. When this setting is enabled, hardware transcoding cannot keep up with the stream. If I disable the setting, I can have multiple streams/conversions running simultaneously. Is there…

Are you using the 32 or 64 bit version of Plex? [image] How do I make sure PMS uses new GPU? Desktops & Laptops Ok guys. Hardware tone-mapping is still experimental but is enabled in the 64-bit Windows version of PMS for NVidia GPU’s. This is made possible because of the…

I can confirm I was having the exact same issue when using hardware decoding on a RTX 2080 Ti, which should handle a single 4k transcode perfectly fine. The problem was also having HDR tone mapping enabled in the 32bit version … I have since installed the 64bit version and re-enabled HDR tone mappi…
