Modern games often require significantly more storage than their listed install size due to day-one patches, DLC, and updates. For example, Fallout 76 launched with a 54GB patch on top of its 45GB base game. Developers frequently release bare-bones versions at launch, pushing additional content as downloads.
Even after uninstalling, some data like saves, screenshots, and shader caches remain on your drive. Language packs and unused voice acting can also consume extra space. Steam may require more free space than the download itself while applying patches.
Console features like PS5 trophy recordings can silently fill storage with HD videos. To manage space, disable automatic captures, delete unused language packs, and clear shader caches regularly.
