Why is Minecraft lagging so badly with me?

Yes, my internet isn't the best in my room, but a few months ago it wasn't too bad and there weren't any frequent jerking either. Gta 5 doesn't lag with me either! Do you have any tips on how to pick them up?

Is it that bad all the time?

Is it just your pc? Or also on your parents' cell phone or other Ebdgeräteb?

Have you ever restarted the router?

You could also consider setting up a LAN connection.
