Play with your hardware buffer--I find that 256 & 128 will Only work for me. Also, play with your DAE buffer... When you have PTLE up, go to the upper right of your Mac screen, in the Application Popup Menu, and select DAE, then in the file menu select "buffer" and go all the way to the highest setting for the most punch available...Your starts and stops will be a little slower... YOU Must ReLaunch PTLE for the New DAE buffer setting to work... You can also experiment with the combination of the Hardware and DAE buffer. You will find the optimum settings for your rig...

Also, assign a little more RAM to DAE than PT. For example, 70 to PT, and 110 to DAE or whatever. And try processing any RTAS plugs as AudioSuite instead, as they take much less processing power...Hope this helps...
