>There was another research which discussed about a latency in the brain of around 15ms. Even if the visual system could detect a change, not much could be done with that change due to the inherent latency.

That claim does not support that conclusion. 15 ms is roughly the frame time at 60 fps, meaning framerate potentially accounts for a significant and reducible portion of overall latency.

A 45,000-pound airplane has a slower response time than a cursor on a videogame.

The research was in relation to HUD for fighter aircraft from what I recall. Nothing to do with how the aircraft responds rather identifying targets on screen.

Note that hearing and touch have higher "frame" rates.
