DirectX 11 tracking "inertia" in unity

After some experimentation with the unity intigration I've found that you get a strange "inertia effect" when moving your head when DirectX 11 is checked on in player options in Unity.

The effect was first reported to me by drash after playing "The Room". I narrowed it down to the DirectX 11 option and it was reported as fixed.

I also created a basic scene in Unity and tested it off and on. Same thing. Weird head lag with it on and smooth as silk with it off.

Not sure if this is a known issue. Searched the forums and didn't find anything.

This is fairly critical if confirmed. This effect contributes a great deal to the VR sickness epidemic being reported by many.

    I ran across this problem as well, and I found what I think is the issue and have reported it to Unity. Please see this reply on another thread for more info and a decent workaround:

    I don't like cross posting on threads like this, but I figured this might help out more people this way and I started here in my search for a solution.

    Thank you so much for posting this, it fixed the issue for me!! (Nvidia setting)
    Edit: Looks like Drash helped as well with similar settings (above)
