After investigating the issue where the patch size of the update released on April 4, 2018 had become 24GB, we discovered that there was a service problem occurring in the differential patch distribution system of Sony Interactive Entertainment, that is used by Gran Turismo Sport.
The issue persisted during the following dates and times:
Monday, April 2, 2018 14:00 – Wednesday, April 4, 2018 23:30 KST.
This issue has now been resolved.
We apologize to the customers who had to undergo this massive update.
Performing the update with this 24GB patch size will have no adverse effects to the game play.
