CPU usage limit question in PT

[walkperson]

Hi folks

I'm using PT 7.3 with a Macbook Pro and am having some problems with the Playback.

when I record enable a track and start to record the track stops and asks me to increase my CPU usage limit or remove plugins'.

I've adjusted the settings in the Playback Engine but keep getting the same problem...

It's kind of bothersome...

Also the audio waves lag behind the recording...it didn't do this before and computer's only new. perhaps i changed a setting unwittingly...

Any ideas?

Thanks a lot
