This is just rediculous, Last night i tried playing mw2, And switched it off after a few games, Getting mowed down by 3 bar players, When i have 4bars, Not getting chance to react, Going through my bullets and knifing me, Stuttering 1 on 1 incounters because lag comp over compensates tenfold, Every match is like this, My days of buying games is way behind me, I'm not going to support companys, That are not supporting me.

Might want to check the battlelog forums.

BF3 on the PC is known to be rather poor for multiplayer netcode.
