War Thunder update stuck on Steam
Endless update or download in Steam
Steam keeps updating or downloading War Thunder and never finishes. Gaijin's fix makes Steam check the files you already have instead of starting over.
Fix it
How to fix it
Pause the War Thunder download in Steam.
Rename the War Thunder game folder, for example to War Thunder1.
Uninstall War Thunder in your Steam library.
Rename the folder back to its original name.
Click Install in Steam so it checks the files and downloads only what is missing.
