Update on my Battlefield 3 problem, please help me! #BF3

Ok, so i checked some stuff when the studder was happening, and as you can see in the pictures below, i dont think there is anything special about it? But maybe some of you may know more about this stuff. There are 3 screenshots, one of them is while the studder is happening, the other is normal gameplay and the last one is a few minutes after i quit playing Battlefield 3. The original post is below the screenshots, as well as a video showing the lag/studder in action. So if someone of you might have an idea what could be wrong, please help me! :)


This is when the lag/studder is happening

This is when the game behaves normal


This is a few minutes after i quit playing.




This is why I don’t play Battlefield 3 that often, these pesky and weird lags I get sometimes.

My video settings is set to Auto, but most of them are high.
Only a few at ultra. It happens randomly and is very annoying.
Sometimes it doesn’t happen at all. Sometimes 1-2 times per game.
Checked all gpu/cpu fanspeed/heat when it occurred and there was nothing out of the ordinary going on. Battlefield 3 is the only game that I play that does this. So if anyone know what might be the problem, please post a solution, tips & trix in the comments.
I have tried shutting down antivirus while playing but no luck.
I have the latest driver for my gfx card, and updated DirectX.
