Makes VR "direct" movement based on the direction you're looking at, instead of the off-hand's direction.
This movement style makes it easier to use certain weapons without adversely affecting movement.

If you want smooth turning, in addition to HMD movement (or just smooth turning), you're better off using VR Improvements instead of this mod. You also don't need this mod if you're using VR Improvements already, as it offers a setting for HMD movement.
