Micro stuttering is when your computer or video game seems to pause or freeze for a very short amount of time, like a hiccup. It's very quick so you might not even notice it at first, but it can happen a lot and be very annoying. Imagine you're walking down the street and suddenly you stop for a split second, but then you keep going like normal. That's what micro stuttering feels like for your computer or game. It can happen because the computer or game is trying to do too many things at once and it can't keep up. It's like if you try to juggle too many balls at once and you drop one for a split second. This can happen more often if your computer is older or if your game settings are too high for your computer to handle.
