That’s normal — your CPU is busy rehashing every major PAK file. Let it finish. On an old HDD, this can take 5–10 minutes.

When a game launches, it needs to verify the integrity of its PAK files—ensuring no corruption, missing data, or tampering (anti-cheat). Without a cache, the game would have to re-hash every PAK file every single time you start it. For modern games with hundreds of GB of PAK files, this could take minutes. gfpakhashcache.bin

However, if you find this file in a strange location (anywhere other than your AppData\Local\NVIDIA or Temp folders), or if your antivirus is specifically flagging it, you should run a full system scan.

The hash cache has mismatched entries for your save files. Fix: Delete the file (per Method 1 above) and restart.

: Instead of scanning multiple gigabytes of archived data to locate a specific texture, the engine reads gfpakhashcache.bin directly into the Switch's RAM. This allows the game to find the exact file container and byte offset in milliseconds.

The gfpakhashcache.bin file functions as a global lookup dictionary for the game engine. It catalogs the locations of data across all packed archives without forcing the Nintendo Switch hardware to scan every individual .gfpak container on the storage card. Key Performance Benefits
