Seems very similair to what i was getting last week, i fixed it by using a user.cfg file such as this.Need assistance if possible.
I play mainly ultra 1680 x 1050 on a 6970 and I52500k @ 4.3 , 8G ram.
FPS are above 50FPS and average around 65 - 70. im getting slight mouse lag at these FPS is this normal i have to drop down to low to get no mouse lag at all.
surely an average of 65FPS is enough not to warrant input / mouse lag. effin game.
Rat 5 mouse using Raw input.

Download the above file and save it in your bf3 folder.
Yep, some server admins dont like to see players with a high k/d ratio, butthurt idiots tbh, unfortunately as there are so many cheats about, the decent honest players get tarred with the same brush. Kinda sucks if you ask me.
