Modern Warfare and Warzone Update 1.34 Patch Notes

File sizes are huge

by Damian Seeto


Update 1.34 has arrived for Call of Duty: Modern Warfare and Warzone, and here’s the full list of changes and fixes added with this patch.

Much like many other Call of Duty updates, the file size today is really huge. The PS5 and PS4 versions of the game are both 52GB each! The Xbox Series X/S and Xbox One sizes are 57.8 GB. The PC version is 52.4 GB for Warzone only and 133.6 GB for both Modern Warfare and Warzone installed.

Raven Software says the reason the file sizes are so large is “due to the optimization of data.” You may also want to invest in more hard drive space if the game is taking too much room! You can read the patch notes posted down below.
