    I'm using vlc player to watch Life of Pi in 4k but it keeps stuttering and getting image errors.
    Is this a limitation of the machine or is there something I can do about it.
    CPU usage is maxed out.

    can try using a different player software package like 5Kplayer for Mac, but it seems to be more of a system/GPU issue. I can make my 2015 playback smooth with bootcamp and either VLC, 5K or best of all Plex or Kodi.

    How was the video encoded? Sounds like its too complex for your system to decode in real time.
