I had a similar issue, intense stuttering and FPS drops despite other games working fine, for me it was upgrading the RAM and CPU which solved it. An i3 is below what you'd likely want to have for this game so an i5 or perhaps even i7 if you can afford it would be much better at running the game, especially on higher playercount servers like 64 player Operations or Conquest.
While anecdotal, even after upgrading to a 1080 / i7 personally the game continued to have random stutters particularly during explosions or combat which made playing unbearable, upgrading to 16GB of ram stopped this from happening as from what I tested hence it seems the game is very RAM heavy as it is CPU heavy.
I have those problems even tho i have a i7, 16 gigs of Ram PC, the only thing i need to update is my NVIDIA GTX760 graphics card
