Prototype 2 relies on specific DirectX 9.0c DLLs (specifically d3dx9_42.dll or similar variants). Modern versions of Windows ship with DirectX 11 and 12. While these are backward compatible in terms of graphics rendering, they do not always retain the specific helper libraries required by older games for file handling and memory management. A missing or corrupted DirectX registry key can interrupt the process when the game attempts to compress and write save data.
