Server Version#: 4.138.0
Ok new to this site and very new to unraid started new system r730xd with unraid 7 beta 1 installed my new plex docker and Nvidia card P600 with Driver Ver 560.35.03 transcoding and selecting the card in plex as the GPU to use for transcoding no issues
Push forward update to Beta 4 found Plex set to auto and not using the GPU tried adding lines to the Docker rebooting the system than downgraded my system back to beta 1 but noticed it changed Nvidia drivers in the process so upgraded back to beta 4 and downgraded the Nvidia driver back to what it was using in beta 1 V560.35.03 where in beta 4 it switches to V565.57.01
After doing this again transcoding is working and Plex allows me to select my transcoding GPU just like before
so feel that maybe plex is not fully compatable with the new Nvidia driver on Unraid yet
just posting so people can get there plex transcoding to work again
