Every time I alt-enter [change from fullscreen to windowed mode] or alt-tab [minimize the window] my game lags and I disconnect. Can't use potions, skills, or talk to npcs and after a minute I just d/c.
Intel Core i7-3630QM CPU @ 2.40GHz RAM 8 GB Nvidia Geforce GTX 660M 2 GB ^are my laptop specs which is what I usually play on [bug only occurs on my laptop]
Your spec's are better then mine lol, but I think this might be a laptop problem are you running windows 8 by any chance? and if so which version of windows 8?
