How non-real-time OSes like Windows or Linux generate video frames with such high timing accuracy during video/game playback?

They don't.

The frame rate of videos and games on a non-RTOS can vary quite a bit. If the frame rate is consistent, it's because there's something limiting the maximum frame rate, and the computer has enough brute force power to keep the minimum frame rate from dropping.
