Download and Install Origin: http://www.origin.com/us/about1) Create an Origin account, if you haven’t already. You can do so here. If you have an EA account then you already have an Origin account! Make sure you know your account name and password.2) Download the Origin client. You will need to have the latest version (8.3.1) of the Origin client running on your PC in order to play Battlefield 3. To make sure you're up-to-date, we recommend clicking here to get the latest version up and running on your system.
3) Double-check to make sure you have the latest graphics card drivers. Visit the drivers section at AMD or Nvidia, depending on what your manufacturer of choice is.
4) Pre-load Battlefield 3. If you purchased Battlefield 3 through Origin (or any other digital retailer that is offering BF3 and supports pre-load as an option), the game is currently available for pre-load. This means the game will be downloaded and installed already when it goes live. The game will unlock at specific times in each region, and you will not be able to play it before the unlock-time in your region.
