Okay so This problem with minecraft has been slowly getting worse. It started when I was playing there was these white flashes coming on my screen. It didn't seem to affect the gameplay just really annoying. Then I was trying to break blocks and after a few seconds the block would come back in the same place. I have a decent computer and it's played high end games pretty good. The fame still slows down to 15 FPS and it's really starting to piss me off. I just want to know what's happening and if I can fix it. Also adding to the problems sometimes when the world tries to load the whole game crashes and I have to reset my PC to fix it. I'm not tech savvy. At all. So keep that in mind while answering.
