EDIT: Also could someone with a log-in please correct the moderator here: http://www.respawn.com/forum/viewtopic.php?f=24&t=14284 who is being pretty unhelpful just kinda saying "lol you don't meet the minimum requirements.. SUX TO BE YOU". Having a DX10 card does NOT mean you are below the requirements for Titanfall. As evidenced here: http://answers.ea.com/t5/Titanfall/DirectX-10-support/td-p/2471392 and by users who used DX10 cards prior to the most recent patch.
