  2. Type Registry Editor and press Enter.
  3. Now locate the following key:
    HKEY_LOCAL_MACHINE | SOFTWARE | Microsoft | Windows | CurrentVersion | SideBySide
  4. Right-click anywhere on an empty area of the screen, select New | DWORD (32-bit) Value.
  5. Enter PreferExternalManifest for the DWORD Name and 1 for its Value.
  6. Now click OK and exit the Registry Editor.

Freshen Up the Cache

Cache content is being accessed on a continuous basis during the gameplay, for it plays a vital role in ensuring the game performs up-to-the-mark. Since the files in Cache are being accessed and over-written continuously, they sometimes go rogue and cause problems. Deleting the contents of CellsCache and CompiledOctreesCache can help in resolving the Subnautica lag issue, provided the contents of these folders have been corrupted.

  1. Open This PC.
  2. Navigate to:
    C:\Program Files (x86)\Steam\SteamApps\Common\Subnautica\SNAppData\ SavedGames\Slot00xx\
  3. Rename CellsCache sub-folder as CellsCache_OLD and CompiledOctreesCache as CompiledOctreesCache_OLD.

Note: Do not delete the files screenshot.jpg, gameinfo.json, scene-objects.bin and global-objects.bin as these files are absolutely necessary for the game to function as intended.
