No, the game will read the cache file just fine. Side note, but with dxvk >= 2.0 and GPL the cache file doesn't really help that much anymore either way and probably doesn't exactly nothing for games that don't use tessellation or geometry shaders like Black Mesa.
Nothing extracted yet.
Question, when Steam writes a game's shader cache files to the shadercache folder due to the shader pre-cache option being enabled, does that prevent the game in question from reading its related cache files?
(game in question is Black Mesa btw; dxvk dll used is 2.2)
