It doesn't run on AMD well because Intel helped program the game naturally they would try and make it so that it would play well and jive with there own architecture. BF3, Metro 2033, Crysis 1&2, STALKER series, Just Cause II, Mafia II and fairly well all others excepts they very few sticklers that were conveniently sponsored and developed in conjunction with Intel such as Starcraft II and Civ V both which are not very graphically demanding games by todays standards run like *** on AMD but not Intel LOL.
