Well. everyone was expecting something little bit different I think. I do not have troubles with logging in, but what troubles me is that the new client uses almost as twice as much RAM memory. Also the the previous client gave much more smoother graphic experience, than this new one. No matter, if I'm using dedicated or integrated graphic card, the outcome is same. I am disappointed to be honest.

Edit: I confess, it is little bit faster ;) but the RAM usage though
