I was browsing some Japanese blog of a player I know, and there were a couple links to interesting programs that I had not heard of before. First, Flash-based tests meant to measure your average reaction time to visual stimulus: http://70.84.61.34/~fundotn/Games-D5-140406/reaction.swf (can be used offline); http://www.humanbenchmark.com/tests/reactiontime/index.php (online with leaderboards). I have an average of 175 ms on those two tests. The second is a Windows-only ABX (blind test) program that measures your sensitivity to input lag. When you start, you need to choose the test variable. "1 or 8" means one subject will have 1-frame latency and the other 8-frame. You can switch between them using spacebar. When you determine the lagged subject, press enter to write down your choice. Repeat until 20 results. So far I've managed to pass 1 or 3 test with 100% confidence, but in 1 or 2 I can only guess. Disclaimer: I'm using a CRT monitor, USB mouse and PS/2 keyboard.

0.248 is the score I got, I used an LCD monitor and a wireless USB mouse. However, it IS midnight, my results may be biased by myself being half asleep.

I was getting about 180 on average, although I did manage a 150 on one attempt.

.226 on the first reaction time test (which I did second); .238 for the second. I also see the same error as Bisqwit for the delay test.

"Genuine self-esteem, however, consists not of causeless feelings, but of certain knowledge about yourself. It rests on the conviction that you — by your choices, effort and actions — have made yourself into the kind of person able to deal with reality. It is the conviction — based on the evidence of your own volitional functioning — that you are fundamentally able to succeed in life and, therefore, are deserving of that success." - Onkar Ghate

2.5… seconds? :D You probably mean 250 ms.

I get different results for each of my monitors, around ~35ms. Considering that at 60 Hz, each frame is displayed for ~17ms, I really wonder where those two frames went. Switching outputs doesn't change that, the delay happens in the monitor. But to actually delay the incoming frames, the monitor would have to buffer those frames somewhere, which would mean that someone built >12 MB of storage into a monitor. WTF?

You're probably talking about LCD monitors' output lag (also known as input lag). They have some kind of framebuffer to do scaling and other stuff.

0.183 average first time. 0.163 average second time. This reminds me of the Kirby Super Star mini-game in which two ninjas face off waiting for a flash and the first one to push the button wins, slicing the other in half. Fun days. L. Spiro [EDIT] 0.148 on my 6th try. [/EDIT]
