Immortals Fenyx Rising has now officially launched. It's Ubisoft's latest open-world action game in 2020, the third in less than two months. And much like Watch Dogs: Legion and Assassin's Creed Valhalla, Immortals Fenyx Rising has a disappointing limitation. It's now confirmed that Immortals Fenyx Rising runs at a crisp 4K resolution on PlayStation 5, but on Xbox Series X, Ubisoft has once again struggled, instead offering a dynamic resolution that drops below 4K.

According to an analysis done by YouTube channel VG Tech, Immortals Fenyx Rising's Quality Mode showed a clear difference between the PS5 and Xbox Series X. The PS5 delivered a consistent 4K resolution, with VG Tech being unable to find a scene where the resolution dropped. The Xbox Series X, however, did drop. It went as low as 3328x1872, which is still an impressive resolution but also still a big drop below 4K. Both platforms likely use dynamic resolution, but the PS5 is simply better optimized.

A notable difference was also found in Immortals Fenyx Rising's Performance Mode, which trades resolution for a consistent 60 FPS. In performance mode, the PS5 was measured to drop as low as 2275x1280, while the Xbox Series X dropped as low as 1920x1080. Neither platform reliably delivered 4K resolution in this mode, but the PS5 more consistently delivered better resolution than the Xbox Series X. This is while still delivering 60 FPS.

Given that these details had to be discovered by content creators, it's fair to say that Ubisoft has not made it clear why Immortals Fenyx Rising has worse performance on Xbox Series X. It's also unlikely that Ubisoft will ever provide a reason, given that it's not a topic that's typically discussed by big publishers. Nevertheless, for Xbox Series X players of Immortals Fenyx Rising the news is certain to be somewhat disappointing.

Immortals Fenyx Rising, as noted, isn't the first next-gen Ubisoft game to perform worse on the Xbox Series X. Both Watch Dogs: Legion and Assassin's Creed Valhalla perform worse on Xbox Series X compared to PS5, in both small and large ways. Assassin's Creed Valhalla specifically has very similar resolution drops to Immortals Fenyx Rising.

Regardless of the unfortunate disparity between platforms, which Ubisoft will hopefully improve in future games, Immortals Fenyx Rising does offer overall impressive visuals. To imagine games consistently providing visual modes with 60FPS and dynamic 4K resolution so quickly, it's a very impressive step forward.

Immortals Fenyx Rising is available now on PC, PS4, PS5, Stadia, Switch, Xbox One, and Xbox Series X.
