Battlefield 4 laggy playing single player

[Rafael Mestdag]

I can play Battlefield 3 without any lag at all but BF4 is lagging like hell, it's small lags every couple of seconds and it's driving me nuts. So far it's the only game to lag like that.
What could it be?

My Rig;

Windows 7 64 Ultimate
Gigabyte GA-78LMT-S2
AMD FX6300
1 HDD 1TB Seagate 7200rpm
1 HDD 500GB Western Digital 5400rpm
1 HDD 320GB Seagate 5400rpm
GTX 460 1GB GDDR5
8GB DDR3 Ram
500W Generic PSU

Thx in advance for any help!

Well if it's single player it's impossible for it to be lag. Just sayin'

Ok, I've found this page from Toms Hardware which solved the problem:

The word I should've used was stuttering.
