Fast App Switching is a new technology introduced in C64 OS version 1.05. It requires a 17xx-compatible REU (RAM Expansion Unit) and enables exceptionally fast and efficient computer interactions.
Observe how quickly users can switch between open applications. They can even launch a game directly from the App Launcher and, upon finishing, quickly boot back into C64 OS right where they left off. Fast App Switching is a transformative feature for the C64.
