I have issues with Precision X16 and movies.
Whenever I try to watch a movie (or any clip really, with VLC or Win Mediaplayer), after a while the video stops updating. I can still hear the sound but no moving pictures. This can happen 2 minutes into the clip but especially if I use some other program at the same time. Doesn't matter what program, as long as the movie player is out of 'focus' = isn't the main, highlighted window on my desktop.
Shutting down EVGA precX16 fixes the issue.
