Secondly, I'm allowed to at least tell you about the new networking code. Yes, we all thought it would be in the previous patch. However, if you will recall, the previous patch was rushed out to address some issues for the CS players with people being able to see through walls. I can tell you that the code is very nice.

Your connection is no longer the slowdown, it's now your graphics card and processor (the way god intended).OMG!!!11
