Just FYI, I feel these two threads are tied to the same issue. Plex for Windows Is Stuttering In Direct Play
If I enable open GL in PMP it resolves almost all stuttering(I say almost, as I see occasional when streaming 4k movies). However, open GL is apparently already enabled on Plex for windows, but I feel implementation is not done right, as it stutters on direct play, live tv, and local and network streaming.
