Hi everyone. I've written some compositions in Quartz Composer and want to demonstrate how they tax the CPU in various conditions. I've opened up Instruments and I can get it to give me a readout for the individual process (Quartz Composer) but I can't see any obvious way to average the CPU load... I can see the peaks, but I'd much rather know what the average is over 1 minute, in this instance (I want to compare different compositions - there's no variables within them as such...) I found a little DTrace script in the apple docs, but couldn't really get it to work... it would quit with an error after about 45 seconds... Anyone got any ideas?
