Plex Transcoding settings for 12th gen CPU with quicksync
I purchased a z690 motherboard and a 12th gen CPU axious to take advantage of quicksync. When I bought the equipment, I intended to stick with windows on my server; however, ended up moving to unraid. I've now realized that the 12th gens aren't fully supported yet. I've read that some have had some success with enabling hardware encoding/decoding etc. Installed the gputop plugin and dev/dri is available so all good there. What is the general consensus of what settings I should use (for now) for transcoding? I have folks I share my library with that never had issues transcoding on my 12 year old i5 processor and are struggling now. Any help with settings/suggestions for the best performance until this setup is fully supported would be greatly appreciated.

I'm in the same boat as you. Same hardware, but every time I add /dev/dri as a device to my docker container Plex almost immediately shits the bed. On the plus side I have 4 streams running right now and only 5% CPU usage.
You can make it work but you'll end up with random system-wide hard crashes. Hard crashes on a file server are very bad.
I found my system would crash roughly around 9-18hours, sometimes it's last a couple days, sometimes it just crashes in a couple hours.
There's no way to avoid that right now.
12th gen isn’t fully supported in the current stable kernel. 6.10 should bring support at a level that’s usable.
I had the exact same issue. MSI Z690 with i7-12700K. Win 11 and replaced with unRAID. Ended up going back to Windows until there's a little more stability. It's not like Windows is bad, so I can wait a year.

I could not get gputop to work for the life of me, I had to ask for a refund from unraid, I'm a Linux noob.
The problem you are highly likely to experience is system lockups during transcoding, at random. Itll work, but then 6 or so hours in, hardlock. For now, CPU transcode and wait for unraid to release with a 5.15, or preferably 5.16 kernel.
This is the price you pay for being an early adopter of stuff. It was pretty well known the 12th gens were not supported yet in unraid. Why not go back to what you had until this is better supported in a few months? Other options: Buying a p400 for cheap if you have a pcie slot available and selling it once you don't need it anymore
I have been trying different setting for weeks, still no go. I have been running RC 6.10-4
