Game stutters while recording with webcam on

I have a problem with recording my ea fc25 experience while playing. When I'm recording with webcam on, the game stutters. I've tried turning off the " game mode ", updating my drivers and changed the  graphics in game. While recording with obs studio without my webcam on, the game works perfectly. But when I try to record with webcam on, the game starts to have these mini stutters through the game. Can anyone help me with this ?
