I am running Pro Tools on a mac G4 1gHz powerbook with 768 megs of ram. It doesnt quite run as smoothly as I would expect... how can I tweak it to make it run more smoothly? Its a 12 inch powerbook that I have connected to a 23 inch cinema display. When the display is connected, I noticed that the screen redraws itself less smoothly.. can this be most of the noticed performance difference?
Also, I used to run pro tools on a g4 867 Mhz with 640 megs of ram (also a powerbook). It actually seemed to run faster on the slower computer because it wasnt hooked up to a large monitor. I cant imagine that anything other than video memory is used to handle the cinema display. I did some testing on the faster pb without the monitor and it did seem to run a little faster.... Whether the display is affecting it or not, it does seem like there should be something I could do to assign the application higher priority while its running. When I run "top" from the unix command line, it seems that not all my available physical memory is being used and that a million processes run that Im not using. Is there anything I could other than buying a dual G5 (which I am scheming for continually)?
