FPS Drops? (PC)

What the hell EA? I thought this was answers HQ? I haven't seen a single EA post on this thread. All i see is "Same problem here *posts computer specs* Where the hell are you money hungry warmongers? Answer our damn questions

Since BF4 PC LAUNCH I've had this random FPS drop every few seconds. i KNOW It's not my setup because i can run EVERY GAME EVER on my PC with atleast Medium-high Graphics settings and get a constant stable FPS amount. 

I get 70-80 FPS ALL DAY on LOW setting in BF4 but like EVERYONE ELSE HAS SAID every few seconds it spikes down to about 20-30 and i died from not being able to shoot some one or my helicopter crashes because my screen gets jumpy. I'm tired of this, You've banned me from forums before for venting and im tired of it. WE ARE THE CUSTOMER, You are the cracked out Developers and you SUCK! What the hell did we pay for? **bleep**! i don't like paying for **bleep**, if i wanted some i'd wait for my dog to go outside and i'd hold my damn hands out expecting his nice warm pile for FREE. instead of paying for it like i did your **bleep**TY GAME!
