7. Post-Install Verification



After installation, confirm the game is fully functional:

1. Check file integrity (optional but recommended):
- Steam: Right-click game in Library → Properties → Installed Files → Verify integrity of game files.
- Epic: Library → click three dots on game → Manage → Verify.
- Microsoft Store: Settings → Apps → Total War: WARHAMMER III → Advanced options → Repair or Reset.
2. Launch the game – It should start to the main menu without errors.
3. Check version number – Usually displayed on main menu or in the launcher. Compare with the latest patch notes from [Total War blog](https://www.totalwar.com/blog/).
4. Test performance – Run through the prologue battle. If severe stuttering, lower graphics settings or update drivers.
5. Enable mods (optional) – If you play on Steam, subscribe to a few harmless mods (e.g., UI improvements) and ensure they load correctly.

8. Additional Tips



  • Storage Optimization: The game uses ~120 GB. If you have multiple Total War games (Warhammer I, II, III), they can share some data for the combined Mortal Empires campaign? Actually, Warhammer III includes Immortal Empires, but you still need all three games installed to unlock full 2/1 factions if you own them. However, you can install them on the same drive.

  • Uninstalling: Use the store client’s uninstall feature. Do not manually delete folders – remnants may cause issues.

  • Cloud Saves: Enable cloud saves in your launcher (Steam: Properties → General → Steams Cloud; Epic: Library → click three dots → set cloud saves on; Microsoft Store: automatic with Xbox Live).

  • Mod Management: Steam Workshop is easiest. For Epic/MS Store, mods must be installed manually (rare).

    9. Frequently Asked Questions



    Q: Can I play Total War: Warhammer III on Mac or Linux?
    A: No. The game is Windows-only. It may work on Linux via Proton (Steam Deck has a specific version), but not officially supported. Mac support was removed after Warhammer II.

    Q: Do I need the previous games installed for Immortal Empires?
    A: No, you only need to own them on the same store. You can have them installed or not; the game will detect ownership. To play with all factions from Warhammer I and II, you must own those games and any relevant DLC on the same store.

    Q: Is there a physical disc version?
    A: Very rare. Most physical copies are just a code in a box. No disc installation.

    Q: The download is huge – can I play while downloading?
    A: Some launchers allow playing while streaming (Steam’s “Play while downloading” feature) but not for Total War: Warhammer III; you must wait for full download.
