Problem with recording in Battlefield 3

[cashpoint187]

Hello, i got a problem with recording in BF3... I installed it 4 days ago and i started bandicam...everything was OK and i made some videos, but from 2 days ago(maybe) i got problems with it... it doesnt even show me the green fps in the corner. I tried to record in other games and everything is ok, that problem only remains in BF3, dunno why...I tried to record in default preset and its ok, but on 720p it dont want to record...soz for the bad engl
