Ubisoft has released a patch for Assassin's Creed IV: Black Flag on PS4 which increases its native resolution to 1080p.
As the firm announced last week, the game was shipped running at a 900p native resolution at 30 frames-per-second. Once installed, the game will be running at full-HD 1080p natively, expectedly at the same frame rate.
According to Ubisoft, you may not even notice the difference. "If it [was] running at 720p vs 1080p, you're going to notice the difference, by far," said associate producer Sylvain Trottier.
The publisher said it shipped the game running at 900p to ensure a 30 frames-per-second refresh rate at launch.
"Finishing the game at 900p gave the development team the extra room in terms of the GPU and CPU usage to ensure the framerate never dips below 30 frames per second," explained Ubi.
The patch also adds "a brand-new anti-aliasing technique", which helps reduce the appearance of jagged edges on-screen. The new anti-aliasing will be active in both PS4 and Xbox One versions of the game.
There has been no mention of the Xbox One version's native resolution output.
In CVG's Assassin's Creed IV review, we said, "Much like the first Assassin's Creed, Black Flag isn't perfect. But the treasure trove of memorable experiences on offer here put all but the very best open worlds to shame."
