File type: Game file
A .fxcb file is a shader cache generated by Crysis, the 3D shooter for Microsoft Windows.
The game uses this cache to store compiled shader data for later loading.

The FXCB format is associated with Crysis, a 3D action shooter developed by Crytek. The game creates these files as part of its normal operation.
An .fxcb file contains cached, already compiled shader data used by the game's graphics engine. It is a supporting cache file rather than a user-created game document.
Deleting the cache forces Crysis to rebuild the compiled shaders the next time it loads. The format is intended for the game's Windows installation and is not generally used outside the game.
Crysis opens and uses .fxcb files automatically. There is normally no need, or supported way, to open the contents manually.
If the cache is deleted, start the game again so it can rebuild the required shader data.
An .fxcb file is a game-generated shader cache and is not intended for conversion.
