I just started my first playthrough on this in the XBox version of this game. I ran into a similar problem with being unable to get a single hit on these decrypts, I mean I could barely get one let alone the minimum of three a row. After some thought, and a few brews I started to think about how I had the system hooked up to the television. Sure enought I passed the HDMI through the XBox One and to the TV. By disconnecting the XBox from the XBox one and running it straight to the TV I noticed a drastic decrease in the amount of time that the key procs to when I have to hit it. I'm getting close to every one I run into now. So heres a heads up: this can be possible for any case where you pass your HDMI through the reciever, XBox One or any other device that has HDMI pass through. It has a chance of reducing the speed at which the game knows you see the button light up to when you actually see it light up on the screen.
