I’ve got a I3 with Intel graphics, Emulation was apparently fine, But for no reason, it gets too slow. I have cheked for other apps running at the same time. Nothing. I reboot the computer to clean the cache, nothing. I turned off the automatic updates. Yet the same, it is as if the video work whenever it feels like it.
Which application has slow video? Playing videos in VLC or Youtube? Or do you mean the graphics output is genereally slow, e.g. when dragging around Windows.
