I have 5 PS4 controllers.  I need to use a single controller at the same time on both devices with no variations in input or lag.

That seems impossible due to how the same game on different systems tend to have different input delay.
Or is that what you want to test, by comparing the PS4 version of a game to the PC version?

That's what I wanted to measure.  I can already do this by connecting the controller to usb on PC, and blue tooth on PS4, but I've discovered blue tooth to drop inputs, so I try not to use the controller wirelessly anymore.
