And by a not inconsiderable margin.

I've decided to create a thread specifically about this. With the release of the new DS4 with its USB option, most (all?) people assumed that input lag would be reduced, e.g. see this article http://www.eurogamer.net/articles/2...e-specs-new-controller-and-everything-we-know
Now, so far as I can find, no one has actually tested this. Except me.
One of the threads that I found very interesting was this one
http://forums.shoryuken.com/discuss...stick-input-lag-testing-results-thread#latest
which compared the input lag for various different sticks/pads for fighting games. I went about developing my own method for analysing input lag, which I can go into (significant) detail about, but the summary is, it uses an arduino to send an input to a controller(s), and at the same time it watermarks the screen (by removing colour, hence the fluoro lighting in the video in this post. Capturing this provides a very accurate way to determine input lag.
On going through various different controllers, one of the things that surprised me was how slow the wired DS4 was. If you look here https://twitter.com/noodalls/status/816578228676534273 (sorry for using twitter, but I find it is an easy way to upload images) the DS4 wired is some 7-10ms slower than the DS4 wireless.
Now, you could take my word for it, but instead I'll post a video which should hopefully demonstrate it. As I mentioned, you're going to have to ignore the fluoro lighting, it does serve a very important function, but you'll have to just accept it for now.

Now, if you watch this video in HD (720p60) you should be able to advance frame by frame (using the , and . keys). Skip ahead to 0:20, and advance from there. When you get a green bar on the screen (happens every 24 frames), this is when the input has physically occurred. If you advance three frames from there, you will see P1 (red, wireless) duck, and P2 (blue, wired) still standing. If you advance one further frame P2 will duck. What is happening is that the wired DS4 is lagging behind the wireless DS4. If you can't do that, just look at these two tweets,

(deleted old tweets with incorrect text, uploaded same images with correct text)
as they show the same thing.
I have tested this on at least three separate occasions, with consistent results each time.
Any thoughts? Has anyone else tested this? Given they differ by about half a frame, it shouldn't be too hard for someone to either corroborate all of the above.

I think future input lag tests should use wired controllers.

It'll also transfer data over USB when plugged into the PS4, reducing the very slight Bluetooth lag seen in the launch controller. This feature isn't exclusive to new PS4 models - it'll also work if you plug the new controller into a launch PS4 also.
