144hz busted on controller

Okay, before I begin, yes. I play Reach on a controller on PC. That’s how I’ve always played and it’s how I always will.

That said,
I have noticed that it seems that Reach runs at 144hz perfectly fine if I use my mouse and keyboard. If I use a controller at all though, I can only turn in 60hz. This is a minor complaint, I realize, but I’m just curious. Do you guys experience this same issue?
