I will be playing when all of the sudden everything that was moving keeps moving in that direction sometimes going through walls until I find myself a few seconds later somewhere else along with all of the enemies. It is really annoying and I have died several times because of it.
I have a Macbook Pro and even when I change the graphics settings it doesn't make a difference. I have great internet and a good computer, but somehow I will start to get these lag spikes for a few seconds. I will always have a 3 or 4 bar connection so I don't know whats wrong!
