Your report on European patent application number 778 536 states that: “to keep [Nintendo game] players on their toes one frame [of the image] is drawn on-screen while the data for the next is being prepared” (This Week, 20 September, p 13).
We have been doing this for donkey’s years. It’s called “double-buffering”, and is used in almost every application that requires animated graphics. I am certain it’s been in use for at least 15 years. Or maybe I’m missing something here?
