One really nice upgrade i just found was the changing resolution in options. In my case with a 40" led i set it to 1600x900, and then full screen, and the next game i played was so nice, compared to all my other games in windowed 1280x800. I realise this was possible with the old client aswell, but it required a restart of the client. When i close the game it reset backs to 1280x800 and sometimes i forget to go 1600x900 and full screen, but this was all in all a very nice upgrade from the old client. Although full screen seems to generate more bugs(to me), spescficly in observing other games, or joining a custom game in custom lobby, i can click on the game i want to observe but nothing happens. Anyways, as i said i liked this feature alot, and when i remember to go full screen i appreciated the whole experience of the new client and game because in the old client it required a restart and i never bothered with it.
