Update 4.01 has been released for the improved version of The Witcher 3, improving the performance of the game

PC Changes

• Fixed an issue where screen space reflections on PC were not working even though they were enabled. Players who previously had this setting set to a high value may notice a change in performance.
• Added a new performance mode for ray-traced global illumination, available to players with compatible hardware. It improves frame rates by prioritizing performance over range and accuracy.

Quest and Gameplay Changes

• Fixed a bug in the quest “Preparing for Battle” that made it impossible to talk to Avallac’h when the objective “Inform Avallac’h that everything is ready” was active.
• Fixed a bug in the “Family Matters” mission that caused the game to crash when going to the “Ciri’s Story. Out of the shadows” during a conversation with the Bloody Baron.
• Fixed an issue in the King’s Gambit quest that made it impossible to fight the second Wildkaarl due to an invisible obstacle.
• Fixed a bug in the Wine Wars: Belgaard quest that was not fully resolved in patch 4.00, due to which the quest could not be completed if one of the monster nests was destroyed earlier.
• In the mission “A Dangerous Game”, the appearance of the armor in Caesar’s room should now change if the alternative appearance of the Nilfgaardian armor is enabled.
• The puppet enchanted by Axii has increased health and damage.
• The Adrenaline Rush mutation now works as described.
• Minor fixes have been made to tasks and videos.

Localization fixes

• Fixed various bugs in Arabic localization.
• Simplified Chinese and Korean versions of Oriana’s “Lullaby of Grief” have been added.
• Fixed Priscilla’s facial animation to match the Simplified Chinese voice when singing “Wolf Blizzard”.
