On release, the USF4 for PS4 suffered from a number of issues, including choppy menu screens and strange visual bugs like blurry textures, and high saturation for some character models.
Sony's Gio Corsi, a director of third-party production and developer relations, very quickly responded by saying it is exploring patch options. The company has since issued a number of updates and, over time, the game has improved in quality. Though it still not on par with its Xbox 360 and PS3 counterparts.
