At least on my PC with a pair of 60 Hz monitors, leaving GPU scheduling on makes the game unplayable in borderless windowed mode any time there are a large number of players nearby. There are other situations where I get stuttering and freezes with GPU scheduling enabled as well, such as the entrance to Tender Valley, multiple areas in Urqopacha including just to the East of Worlar's Echo, during some attacks in Dawntrail's first trial, and the transitions to and from bosses in the final MSQ dungeon. So far, I have not seen any of these issues after disabling the setting.
