For some reason, one second, while playing minecraft everything was fine, the next, I was going like, 4x speed. For javaw.exe, I tried to set CPU affinity to 0, but that doesn't work. Also, I dont know if this is normal, but when minecraft is running, I have 2 javaw.exe.
Can anyone help?
EDIT: Also, when I create a new world, I move normal speed. Since, I had created a really nice house on this world, I tried to copy the world, but the problem still showed up.
