Ok. I got a new computer a few days ago and i started to play both vanilla minecraft and technic pack on it. It ran perfectly with almost no lag om far render distance, but now something weird is happening to my vanilla minecraft that i can't understand. When I go into a world and stand still everything is fine, but when i try to move/jump the world speeds up! I run like five times as fast and if i go underwater I drowned almost immediately. I have tries deleting ,y .minecraft folder and then downloading it again, but that didn't help. It also can't be a computer issue because my technic pack worlds still run fine. Can anyone help?
Vanilla minecraft speeds up time!
