After upgrading GeForce Experience to 7.0.1, hw transcoding doesn‘t work. I am running the latest version of PMS (1.13.2).
Sometimes it works in the beginning, but switches to sw transcoding after a few minutes. I tried it with Plex Web (Chrome) and iOS. Same result.
Anybody else have similar problems?
HW transcoding will depend on several factors, a lot having to do with the codec(s) in which the media was encoded in.
See the link below in the second paragraph describes it all for the Nvidia Shield.
