Comment Atari 2600 has less latency (Score 3, Informative) 160
On the old Atari 2600, the game has to be written around rendering fields (half frames) of video. On NTSC, that is 59.94 fields per second, or a little under 16.7ms. Input is usually read during vertical blanking between fields. That makes for not much more than 33.3ms latency in the worst case of input change just after vertical blanking.
Maybe new isn't really better.
