If you discover any more, please comment them! None of the sound issues present in the PS3/PS4 versions have been resolved, meaning certain voice lines in fights like Genie Jafar still don't play, sound effects drop during Xigbar's desperation move and during Sephiroth's reaction command, etc.Probably intentional, but pretty inconvenient. It will say the save data is corrupted and won't read it. Save data is non-swappable, meaning you can't take someone else's save files and transfer them to your own.It can detect wider resolutions in the menu, but will either add black bars/letterboxes or use 16:9 stretched. Maybe that's intentional, but basically ruins the main benefit of the sliders in the first place. The volume sliders for music, sound effects, and voice only go down to 1, not 0, so you can still faintly hear them even when turned all the way down.Loading the World Map seems to take abnormally long. Load times slightly slower than PS4, even on an SSD.Despite unclear product page on EGS, it is not dual audio, meaning you can't switch between English and Japanese voices.Minor inconveniences (that can still be patched): Looking at certain animations in a world can cause it to force 60 FPS. Occasional frame drops during gameplay, and almost consistently during loading screens.Variable refresh rate (G-Sync and FreeSync) has been reported to cause flickering. Having V-Sync enabled (by turning on "Refresh Rate" in the settings) butchers the frame rate.Same problem with certain songs in Atlantica. For instance, the F Key icon will always display during Xemnas 1's reaction command regardless of if you're using a controller or keyboard. Multiple instances of the wrong control icons displaying, regardless of which controller scheme you use.It's most noticeable during the 1000 Heartless Battle, as well as killing groups with Fire or Reflect. If you kill more than one enemy at once, the death sounds add on top of each other and can get quite obnoxiously loud. Countless examples of sound effects being too loud.
No consistent crashes so far, just very unpredictable. Biz experienced two, while others have experienced multiple. Problems we noticed watching bizkit047's stream:
