So just had a quick spin on BF4 beta! I know its not optimized yet, but anyone hoping to play this on a rmbp, dont get your hopes up... i was getting about 8fps on auto, and about 30fps on 1200x800 and all settings on low. Hopefully it'll be more optimized for the release or whatever but so far no good! Desperately need that 750m 2Gb!!
