Someone clued me in on another post, but basically it copies your game, then patches it. It's just a horrible way to patch things.

Sounds about right, it's been using my enntire disk write/read for a good half an hour and it's still stuck on 56%, which sseems to be the magic number for a lot of people. What an absolute garbage way of packing the game files if this is the only way to patch them. ANYONE with any computing experience in the slightest would know how bad this is.

That's strange. I only have 100 mbps internet and this patch took me less than 5 minutes.
