While Final Fantasy XV on the Xbox One X is the best looking version of the game, the FFXV XB1X patch doesn’t seem to be very well optimized as the game struggles with some framerate drops.

Eurogamer’s Digital Foundry analyzed Final Fantasy XV on the Xbox One X and PS4 Pro, and concludes that the game is vastly improved on Microsoft’s new console, but also states that it needs some extra polishing. Three visual modes are present following the XB1X update, and the ‘High’ mode appears to be mode of choice on Microsoft’s console.
