Bf4 seams to get really bad frame rate for me. I have two PC's one has 4 gb's of ram, the other one has 8 gb's and for some reason the 8 gb one is getting horrible frame rate on BF4, compared to the 4 gb one which is getting 60 fps on ultra. I also have a internal drive on the 8gb one, and bf4 is installed on this external hard drive. So is installing the game on an other drive other than C: bad?
