If the game fails to regenerate the cache, the engine might be looking for a base template that is missing.
This process will download any missing engine resources, including shader manifest files, allowing the game to build the cache.
You typically encounter a request to download this file in two scenarios: Global Shader Cache-pc-d3d-sm4.bin File Download
Compiling shaders is computationally expensive. It takes raw C++/HLSL code and turns it into machine language your specific GPU understands. If your PC had to compile every single shader from scratch every time you launched a game, you would experience:
The Shader Cache solves this. The first time a game needs a specific shader, it compiles it and saves the result as a .bin (binary) file on your hard drive. The next time you play, the GPU simply reads the pre-compiled shader from the cache instead of re-compiling it. If the game fails to regenerate the cache,
The only safe source for Global Shader Cache-pc-d3d-sm4.bin is your own computer generated by your own game, on your own GPU, with your own driver version.
If you choose to download it manually, place it in the game's root folder (where the main .exe file is located). For example: This process will download any missing engine resources,
C:\Games\GameName\Global Shader Cache - pc - d3d - sm4.bin
Do not rename the file. The game executable looks for this exact filename.
