That’s so true. Amiga didn’t have an RTOS, but it sure felt like it. Windows had so much latency in comparison that I couldn’t bear to use it for the longest time.
The maneuver that always astounded me at the time was right clicking on the menu bar and pulling it down, to reveal whatever application was open on the "screen" behind it. (The Amiga had separate windows and screen abstractions, though I don't recall if I'm using the right terms.) No matter how heavily loaded the system was, whether it was doing floppy I/O at the time, etc., that pull down motion never became choppy. It did feel a lot like an RTOS in that respect.
You could overload the system in other ways though, particularly disk I/O in Workbench.
Even more mind blowing is that the visible screens could have different resolutions. The display hardware could switch modes per scanline while keeping the same output frequencies, so you could have a low-res/high-color screen on the top half of the monitor with a high-res/low-color screen on the bottom half.
