Yeah, they definitely do. I have a steady 180 mbps dowwn, 25 up, and my ps4 is the only device I use that I don't get to use that speed. They absolutely throttle, but, I think Microsoft does too. I don't mind it that much, as they have to manage traffic. But the ps4 is slower than my x1 downloads, no doubt about that either.
Edit: I am downloading the bc gears games now to my x1, downloading at 92 mbps.
