You’re due to receive a key today if you pre-ordered the PC digital download version of Battlefield 3: Limited Edition on Origin, registered a new copy of Medal of Honor: Limited Edition/Tier 1 Edition, or bought Medal of Honor Limited Edition from Steam before July 16.
To access it, go to the Medal of Honor: Limited Edition/Tier 1 Edition page on Steam and click the “CD Key” link on the right side of the page. You should see a “Battlefield 3 Open Beta early access” key. Load up Origin, click the “gear” icon in the top menu bar and select “redeem product code.” Then have a little celebration.
Next, check your drivers are up to date. Both Nvidia and AMD have released new drivers to help Battlefield run as efficiently as possible. Nvidia reckon that the new drivers increase performance by up to 38%.
I think you need to get the DirectX 10 or 11 compatible Nvidia or AMD ATI card
