What did you guys expect, Your playing a Alpha build ( an unfinished version of the game). It was released so DICE can get some feedback on how the servers preform and various PC hardware. The information DICE will gather from players will allow the programmers
to fix issues.
The alpha was released so DICE & EA can test their servers, its not a game-play test, they will be testing that part of the game in Sep on the open beta. Also when you downloaded, install and played the alpha you agreed to Terms & Conditions, that any bugs
you come across will be reported via the alpha forums on the battlefield website.
If you are having problem accessing the game with your current PC spec. You need to check that your PC meets Min Requirements and if it does than you should in form DICE or EA. This will help gamers more then just posting a warning to fellow gamers here.
