If you are seeing the message "Game data preparation is not yet complete" in Devil May Cry 5

A corrupted download cache is the number one cause of this error persisting after the download is finished.

It’s a frustrating scenario. You’ve just downloaded Devil May Cry 5 . You’ve got your headphones on, ready to unleash Dante’s Cavaliere or charge up Nero’s Exceed gauge. You click "Play." The screen flashes, the logo appears... and then nothing. Or worse, a cryptic message stops you cold:

Modern consoles use a "Play as You Download" system. Devil May Cry 5 uses this to let you jump into the action early, but it doesn't always clearly communicate how much progress is left.

: Even if the notification says "Installed," the game may still be pulling another 20GB+ of data in the background.
