From SEGA’s official Yakuza: Like a Dragon live stream we’ve learned that the Xbox Series X version of the game will have multiple graphics options and will not support both 4K and 60FPS at the same time.
You will need to choose from within game either
Xbox Series X
Prioritize Resolution: 4K/30FPS.
Xbox Series S
Prioritize Resolution: 1440p/30fps
Gotta say this is kind of a shame for users looking to get the best experience on Series X at launch but at least we have the option. No word yet if these same options will be available in the PS5 version due in 2021. Based on the videos provided by SEGA the PS5 version looks to be running at 4K/60FPS!
