Has anybody test the input lag on wireless controllers vs wired controllers?
The reason that I ask is that I have built several controllers and went the wireless route. I have always heard the discussion of wireless input lag and I wondered how much lag I was seeing with my wireless controller. To test input lag I used Rock Band lag compensation (I know it isn’t perfect but it is suggestive) and compared my wireless stick to a wired stick.
I performed tens reps and got an average difference of 23ms. 1 frame equals ~17ms and the result is ~1.35 frames of input lag. This is all very rough and would change depending on the accuracy for the Rock Band test and how Rock Band determines the average input lag. Although it suggests that there is a significant amount of lag and could easily be bigger than what I measured.
I realize the implication of worrying about ~1.5 frames of input lag but in a game where reaction time is critical, I think it important to eliminate all forms of input lag possible. Any thoughts?
