The VR system samples at 500 Hz; ergo, according to Nyquist, this means that the effective limit of the system removes vibrations up to shutter speeds of 1/250th of a second - although generally switching it off at the flash sync speed is my rule of thumb.

If you have the VR system on at shutter speeds above the Nyquist frequency, you can have the VR element moving during the exposure and can cause weird losses of sharpness, especially noticeable on high resolution sensors.

There are two major exceptions to this: the VR does stabilize the viewfinder image, so if you're having trouble keeping the AF point on target it's useful at any shutter speed and worth the possible minor loss in sharpness, and if you're on moving platform using support, where the vibrations are transferred to the camera: cars, helicopters, stadium bleachers, etc.

The VR system gives you extra stops to remove blur, but that's only on the low end of shutter speeds, high speed shutters don't need it.
