Ever since launch, many multiplatform games just haven't looked as good (or run as smoothly) on the Xbox One as they have the PlayStation 4. Going forward that gap might be closed. At least a little.
From launch until now, developers had to leave some resources on the console's GPU free for Kinect integration, which had been mandatory. Now that Kinect isn't a compulsory inclusion, a recent code update for dev kits means studios are now able to free up those resources for games, which could (if used) make their titles run more smoothly, look a little sharper or even both.
