I don't know what optimizations have been made since January 2014, but read this page as there WERE a lot of issues such as:
"First of all the GPU usage in Planetside 2 was horrible, where the game wasn’t capable of utilizing the full potential of our standard graphics card dedicated for testing CPUs, the Nvidia GTX 770. No matter what in-game settings we tried the GPU usage was always around 50% (even with Vsync Off!). In order to get the game to fully use the potential of our GPU (100%) we had to... "
and
"When we switched to FX CPUs not only did we have worse framerate but the gameplay was simply put, laggy. The gameplay experience only managed to get worse as we went down from the FX 8350 to... "
I won't bother trying to GUESS your performance as you'd really need a comment from someone with a similar system who plays this game.
If your performance is low there's not much you can do aside from
a) using FRAPS and tweaking the quality settings.
b) other tweaks such as the INI ones mentioned however they may no longer apply so if you do that, try them one at a time and SAVE any configuration files you modify so you can easily reverse changes.
Google online for any NEWER tips/tweak guides.
c) AMD driver updates
d) CPU/Graphics overclock (if possible)
(Find a roughly REPEATABLE area so you can change settings and see if they benefit. Preferably a single-player tutorial or something where you can stand there and turn around slowly to record max/min FPS but I've never played this game.)
