Ok, so I was playing fine all this week but. When I got home I logged on. When I logged in it became really laggy. I thought it was my cactus farm but I went on my ssp world and I looked at my fps. I watched it start at 100 my normal fps then go down to 0 fps. I didn't know what was happening so I force updated, which didn't work. Next I used a 1.3.2 minecraft file back up with opti fine. That also didn't work. Now I don't know what to do. Any feedback would be greatly appreciated.
*EDIT Now I think I might be in some sort of trouble. I deleted my .minecraft file and re downloaded and ran the .exe. Now I go back on and it is still at 0 fps. I really need help now.
*Edit I am really dumb
all I had to do was reboot my computer. You can lock this now even though nobody posted
