The interval between each of the 4 pixel shifted frames is approx. 1/4th of a second. That means, even if the shutter speed and ISO are increased, motion blur is still very likely to happens because of the time delay between frames.
Now, for non moving subjects, I've found that PS yield the best results with lowest possible ISO and shutter speeds set at 1/4th of a sec. because a faster than 1/4th sec. wouldn't make the 4 frames taken much faster, and longer than 1/4th sec. would likely make PS more prone to motion artifacts. That said, you can still use PS in RAW, with OVF and take only one frame when converting to JPEG, it's like having an all electronic shutter while still using an OVF, which means, depending on shutter speed, sharper picture thanks to lack for mirror induced vibration and lack of shutter shock. However, all electronic shutter means that subject motion should still be rather limited not to get any rolling shutter effect. You can try different things and see how results compare.
