Hmm. Next time I do a test like this, I might try to have an LED in-view of the camera so you can see this. Thanks for the feedback. This method would not be at all precise in determining total input latency, but could give a ball-park range of how long it takes to make a specific action with a specific controller/input mode on a specific game using a specific display for video output.I would love to see "the moment of press the button" in the video so that the actual delay can be tested rather the difference between wired and wireless. a 2 frame delay means 32 ms on 60 FPS thats allot! where a mouse and keyboard on pc have less then 1ms
To correctly and precisely measure total input latency between when the circuit switch is closed to when the game code may have access to that input event... well, it would be tricky, and the result would be +/-1 frame (because you can't know when during the frame the game polls the system APIs for input). It becomes extra difficult because you need to know the exact latency (input lag) of your display as well. This test would likely need to involve slow mo video capture which would be very time consuming to capture and analyze. No way I would ever have time to do that.
