Issues with transcoding 4K H.265 with intel i3-8100

[Lauren112]

I've read in multiple forums that the Intel i3-8100 should be able to transcode HEVC 4K HDR content. However, when I try to transcode my movies (I've tested around 10 different 4K films) from H.265 to Full HD or when converting the container from MKV to MP4, the video stutters every 10 seconds. Tautulli shows that the transcode speed is below 1x. I’m streaming these movies over a local network, and I have a Plex Pass.

 

Since I can play these movies on certain devices in Direct Play without issues, I don’t believe the problem is related to bandwidth or hard drive speed. Plex is installed on my cache drive, Direct Disk Access is enabled, and I’m also using 8GB of RAM for RAM transcoding.

 

I’m using an ASUS Prime H310M motherboard, which I know is a budget model—could that be causing an issue?

 

What else might be causing the problem with transcoding?

 

Thanks for the help!

Is your container set to use quicksync (I think that's what it's called with the igpu)?
