PlayStation Preload Instructions

Ensure you have adequate free storage space (recommend 15+ GB) to accommodate all data smoothly.
Preload Tips & Troubleshooting
Storage Management Delete unnecessary screenshots, unused voice packs, or temporary files before preloading. Mobile users should check if old app caches can be cleared.
Download Speed Optimization Use wired connections on PC for faster, more stable downloads. Mobile users should connect to reliable WiFi networks rather than cellular data.
Verify Installation After preload completes, the game won’t launch new content until the official November 5 release. The files sit ready for instant activation when maintenance ends.

Frequently Asked Questions
What happens if I don’t preload before November 5?
You’ll still receive the update normally when version 3.7 launches, but you’ll need to download all patch files during the maintenance window completion rush. This means longer wait times as servers handle massive simultaneous downloads from players worldwide. Preloading guarantees you can play immediately when maintenance ends, giving you a competitive advantage for limited-time events and first-day content.
Will preloading version 3.7 affect my current game data or progress?
Absolutely not. Preloading only downloads encrypted patch files that sit dormant until HoYoverse activates them during the official update. Your current game remains fully playable with all progress, characters, and inventory completely safe. The preload files don’t overwrite anything—they simply prepare your installation for seamless transition when version 3.7 goes live. You can continue daily missions, events, and normal gameplay without any interruption until maintenance begins.
