The guys over at PC Gamer have written up a pretty good basic guide on how to configure Titanfall. It's worth checking out. You might already have tweaked most of these but I'm sure you'll find 1 or 2 tips you didn't know about in there. I definitely recommend unparking your CPU cores, using the VSync tweaks (Nvidia and AMD instructions included), and adding the command line parameters. See my previous post for more command line parameters.
