What? Lets assume 80 characters per line at 60Hz that word to a whopping 4800 bytes per second. For a modern desktop computer moving even a million bytes per second is trivial. Even 10 times that much is easy. In the 1/60th second between cycles a simple desktop computer can execute well over a hundred million instructions. 60Hz is nothing compared to using a computer in a recording studio. Even here at home I'll have 6 tracks of audio sampled at 96,000 samples per second and the computer puts in all file and keeps the displays up to date and doing a dozen or so DSP tasks on the audio streams. Still the CPU meters are no even close to half way. The computer is just a mid-range iMac.
