I noticed something recently, I can help stop the drift by just continually pressing a button on the controller. If I have a button pressed or I am tapping one of the buttons, no drift.
When playing FPS games the controls will drift if you just leave them alone. So, for example, you are sniper waiting on the hill looking down the barrel the gun. it will start to drift. This is a bug, some say it's just due to the inside our tracking.
After I noticed I can better control the amount of drift by just tapping a button, it tells me that Oculus may be able to fix this after all.
