For example, this applies to PvE and PvP, magic, effects, skills, weapons, and so on. In addition, various bugs have been fixed. Even in the patch data, we found references to menu lines related to ray tracing - they did not officially talk about the appearance of the option, perhaps it will be added later.
Games-news24 noted that the patch was not too big, for example, on PC it takes 690 MB, and on PS4 - 1.6 GB. The update itself is also available on PS5, Xbox Series and Xbox One.
