As promised, Capcom has released a new performance patch for both Monster Hunter World and Iceborne. This patch aims to resolve the high CPU usage issue that some PC gamers have been experiencing. It also fixes an issue where the save data would not properly convert to the new file format.
Going into more details, the save data compatibility issue occurred to those that have not updated the game or the saves post Kulve Taroth Update launch on October 30, 2018.
On the other hand, this patch will lower overall CPU utilization on various systems. Do note that this will vary and is dependent on individual user’s PC configuration and hardware component. Also note that these performance improvements are for both the base game and the expansion. Furthermore, and in case this patch does not improve your performance, we suggest giving a shot to this workaround too.
Last but not least, the patch will update Monster Hunter World: Iceborne to Ver.10.12.01.
As always, Steam will download this latest update the next time you launch its client.
