I'm having a nightmare with am i5-12600 and a Gigabyte H610M.
6.9.2 refuses to recognise the iGPU so I've got no hw transcoding in Plex. RC2 DOES recognise the iGPU and transcoding works... but the onboard NIC doesn't work properly and I get all sorts of issues trying to get Plex to connect to the outside world.
