Plus, assets that we created nearly ten years ago didn’t factor in the possibility of being displayed at the high resolutions available to us today, so we have to think about how to revise quite a massive amount of assets efficiently. We do need to take care when planning major updates like this and start with testing and verifying it all works well. Since FFXIV is an MMO, we need to place some emphasis on being able to simultaneously render player characters and their equipment, while still ensuring everything works smoothly. However, we do need to keep in mind that other platforms, including the PlayStation 4 version, are still in service.
We are thinking of eventually upgrading in-game textures in phases and are starting initial preparations for that update.
