Previous promotional footage for Infinite confirmed that the game's PC development team has focused on making sure those cut scenes work with ultrawide monitor ratios.
So far, though, we haven't seen anyone test these perspective-shifting cut scenes, nor Infinite's ambitious open-world environment, on screens beyond the 16:9 standard.
The biggest problem is a constant "frame time" bump when the game's dynamic resolution scaling (DRS) system is enabled.
Because of this, Battaglia recommends enabling Infinite's built-in dynamic resolution setting so that pixel counts can rise and fall to help stabilize performance during frantic, open-world encounters.
