I had been running a basic plex server (plex pass licensed) off my main/gaming pc for a while. Ryzen 5 3600, strix b450-f mobo, 32gb ram 3200mhz c16, strix 3070ti. Shared media with a few friends. Had a library of .mp4 movies that I know 99% of the times played on nearly everyone's devices as Direct Play (yify x264 files).
Recently setup a separate computer with i5 12400, b660 prime plus d4 mobo, 16gb vengeance 3200mhz c16. I believe I did successfully get the igpu setup with HW transcoding, just in case. But had my sister test it out on a few of the movie files and they were transcoding down to 720p. IIRC, I changed all the settings the same on the server settings as I had on the previous setup. Maybe I missed something? Anyone have any insight by chance on what could remedy the situation? ~400mbps download and ~25mbps upload
