On a related note, I just found out that frame dragging is not, in fact, what happens when you don't have vsync on.
well then you wouldn't be moving, and there's still no force 
You wouldn't be moving inside the rotating reference frame, but you would feel the effects of inertia (centrifugal force to something inside the rotating frame).
Inertia and centrifugal force (synonyms in this context): the outward force an object in a rotating frame of reference experiences. Action-reaction pair to the centripetal force.
Centripetal force: The inward force on an object in a rotating reference frame, which is the reason it is rotating in the first place.
The distinction between inertia and centrifugal force seems like a pointless semantics battle to me.
Actually it'd be an accelerating reference frame and would thus perceive a gravitational field permeating the entire universe, or so I believe. It's not an IRF.
That's true, but... honestly if you're in a reference frame that's rotating at those speeds you have bigger problems

An IRF experiences no fictitious forces. Centrifugal force is a fictitious force. QED. There is, in fact, also frame dragging to consider but I've had enough Wikipedia for the moment. Back to teh code... >.>
