WBF

This section only applies to versions ≥ .

WBF files are a cache file, located within the Cache folder. They contain, at the very least, information about graphic card hardware, drivers and software. Each compatible device has it's own named WBF file e.g. DX12ShaderCache_AMD_Radeon_TM_R9_390_Series.wbf. They are only used by the Windows client and only for devices with DirectX 12 support.
