Post-Installation Verification



  • Check Version Number – From main menu, look at bottom-left corner. Current patch (as of 2025) is 2.7.8 or later. If not, check for updates.

  • Test Online Functionality – Create a Seasonal character and try to join a public game. If you get "No internet connection" errors, verify your network.

  • Verify File Integrity (PC) – In Battle.net app, Diablo III > Options > Scan and Repair. This checks and redownloads any corrupted files.

  • Check Storage Usage – Ensure the game is installed on a fast drive (SSD recommended). On PC, the folder size should be ~25 GB.

  • Enable Cloud Saves (Console) – If you have Nintendo Switch Online or PlayStation Plus/Xbox Game Pass Core, verify cloud saves are enabled for Diablo III in system settings to protect progression.

  • Test Controller (Console) – Ensure all buttons work in the main menu. If using a third-party controller, check compatibility.

    Additional Tips



  • Preloading: You can preload the game on PC before purchase if you have a friend who owns it (via Battle.net gift feature) or when you pre-order. Console preloads are available a few days before release for digital pre-orders.

  • Playing Offline: Diablo III on PC requires an internet connection for the first-time login; after that, you can play offline (except Seasonal characters, which need connection for leaderboards). On consoles, you can play offline without an internet connection, but seasonal content requires online verification.

  • Cross-Platform Play: Not supported. PC, PlayStation, Xbox, and Switch players cannot play together. Cross-progression is available only between PC and consoles (limited to Paragon, cosmetics) through Battle.net linking.

  • Antivirus Exceptions: If you have performance issues, add Diablo III folder and Battle.net app to your antivirus exclusion list.
