I have a game concept in mind where the player is scored based on their reaction time to the appearance of a certain sprite. I understand though, that some HTML5 games will run at a higher frame on better systems (and slower on older systems).
My question I guess is: what do you think is the best way to measure reaction time that is fair to all players?
Should I have a time that normalizes the score output dependent on the average fps?
Would wall clock work? since this is frame-rate independent...? I ask because I'm not sure about the mechanics. would the sprite be visible quicker on a faster system and be delayed on a slower system?
I'll experiment some more but I don't know how to test this very well.
Thanks in advance
