My minecraft was smooth at the begining. But then, after a few minute, my minecraft started to lag heavily, that I could not move or do something else. I saw that was "unplayable lag” bug. I tried to downgrade, decrease the qualities of images but these didn't help. I saw that I am not only who has this trouble but there are a lot of people have it too.
