Okay so I've recently upgraded from El Cap to High Sierra on my 13" MBP 2014. But I'm noticing some minor issues such as choppiness with some Apple screen savers like the Arabesque one or lack of smooth animations when switching from the lock screen to the desktop. It's mostly little graphics things like that. Is it simply cause my Mac is older and HS is more demanding? These little things were not an issue with El Cap.
