www.humanbenchmark.com/tests/reactiontime Came across this, seen it before years ago, but I wasn't much interested in it, until now trying to better myself in FPS style games. Actually was posted on a Competition Shooting site, as a way to understand reaction times and how to deal/cope under pressure. There are banner ads, which is dissappointing. It's not intended to be a competition but as a tool to see how you perform and make improvements to your gaming behaviour / style. Remember, not a competition.
