drakHowever: The gameplay itself is clunky. You won't go above 60fps, your aim will not be smooth, and the hitscan itself is shoddy as well (as one would expect with such a large battlefield).
It's perfectly possible to get over 60 FPS in Planetside 2 you just need a beast for a PC to do it (or simply look at the ground in a low pop area). Their's a setting called "Reduced Input Lag" you'll usually get slightly lower FPS because of it but your aim becomes smoother. Finally, their is no such thing as Hitscan in Planetside 2 ALL bullets, lasers, and rockets are projectiles most of which have drop. actually melee might be hitscan but that would be about it.
an i5 @ stock settings whether it's Sandy/Ivy/Haswell, a GTX 660/HD7850, should get over 60fps @1080p with the lowest settings in most battles.
