photo booth and garageband

Ever since i updated to os x mountain lion, photo booth isnt as sharpe as it was iam now delayed a few seconds on it and now when recording on garageband when laying down a drum beat iam unable now to change the tempo.

is there anything that i can do to fix it or do i need to wait for apple to resolve.

very un happy that the £1000 computer i bought isnt doing what i need it to do.
