About 1-2 months ago, BF4 and NVidia released updates that drastically improved performance of the game for my 780Ti. Before the update, on older maps I would average no higher than maybe 80-90 frames, and on newer maps occasionally around 100. After the most recent updates from BF and NVidia, I average 120-144fps on newer maps, and just over 90-100 on newer maps. I haven't mapped anything but I do use the in-game frame count, as well as running on a 144hz monitor that I notice frame dips a lot more on.
