I downloaded Minecraft yesterday to see what the fuss is about, brilliant game!
When playing in Windowed mode, if I try and do anything else, i.e. use the computer, when the game is paused, the computer is incredibly slow, it takes a minute just to type a short message into empathy. Also, once I quit the game, the computer remains slow for about 5 minutes, until it magically frees up and becomes fast again. Could this be related to the 512mb RAM limitation of Java, and the machine is swapping?
Even trying to submit this post is incredibly slow and frustrating, it's taking me a minute just to click in the 'Tag's box.
