That's not a useful description of desktop "creative" software. Even though it might be true for audio that in many cases, the majority of the run time is spent handling the "process callback" from the audio subsystem, once the user starts actually working on things, the slow parts of the code (and the ones that impede the user or degrade their experience) are far removed from that core. This is a little less true of visual applications (video, drawing, image editing etc.) but I would imagine that similar considerations apply there too.
