I have this problem, but I use a Mac, so it's clear that it's not just your computer/OS. Do you get serious client lag and then 5-10 seconds freezing? I can barely move sometimes and have to spam Escape, and yesterday I broke my keyboard in rage; it's now on the floor in two pieces, this is a new one. I don't know how to fix it but it's got to the point where I have to lower the graphics and performance to an annoying bad level to play for more than a minute at a time. I've tried re-installing the launcher and Googling for hours but I have no fix. It would be helpful if someone could help us.
