TZ-AC lags

So basically,

If I play with tz-ac the game freezes for like 2 seconds every couple of minutes and this gets very annoying especially when you are in a gunfight. Is there maybe someone who has also had this experience and can help me out? On the tz-ac forums is not a similar problem and it seems to be quite inactive, so I figured I'd try my luck here first.

No picture for the haters, because this is my first post ever and you'll have to excuse me :)

Cheers!
