lag after playback

I’ve noticed that after playing back a project in Cubase there will sometimes be a lag of about 2 to 3 seconds where I get a beach ball cursor and the program stutters and has to “catch up” to mouse clicks I’ve executed or buttons I’ve attempted to press after the lag starts. Does anyone else notice this?

Have you got auto save enabled?

I’m not sure. Do you mean the autosave on OSX or is it a preference in Cubase?

Nevermind I found it, thanks for your help.
