A few more tips: BF4 settings editor, most of you know of this great tool, If you dont know about it , you are missing out! It allows you at a click of the mouse draw you fps ,cap frame rate ,further reduce shadows, various tweaks, full bf4 game key binding/console/fixes, the list goes on.....(also it creates a user config file allowing for more tweaks-see admin in teamspeak for more info)
So for my personal settings I have done as Oddjob described and in addition cap my frame rate at 120.( no sense in running your card any harder than it needs to) Then I continued to lower my video settings until my fps stays at (for the most part) at 120fps. My monitors refresh rate is well below the 120, so i dont sweat it when it dips a wee bit.
Included in this post is a zip file containing the bf4 settings editor. I think all the bf4 Admins have and most XI members have this , so if you have questions about it, hit them up in teamspeak!
Cheers!
