People that prefer to save memory usage.Okay, so the idea is pretty easy, you've got a Windows pc so you have to download the launcher from www.icecold-wow.com, paste it preferably in the unit where's not the windows installed (most of the time Windows in the C: partition, you should paste it in a new empty folder on D: partition or where you have most free memory). Last time I tried playing ice-cold on a 4.3.4 client I had some problems with the graphic card clustering some red-green phasing.
And that's mostly it, just gotta put the launcher in a new folder and click reinstall game data... Icon is like 2 arrows going to each other.
Hope you get it to work and I hope we'll get to see in-game soon!
