+You are likely experiencing Shader Caching. Shaders are small programs running on a graphic card, responsible for rendering graphics like terrain, explosions, characters, etc. Since a PC cannot directly execute switch shaders, It first has to translate them to a format a PC can understand. This translation process is time-consuming and you'll notice it in two ways:
+
+1). While playing, if yuzu needs to translate a new shader, the game will stutter. Loading into a game for the first time can give long freezes due to the number of shaders. As you keep playing, the amount of stuttering will decrease.
+
+2). When launching a game, the shader cache is loaded. To speed up this process there exists an additional "precompiled" cache. This cache may get reset every time you update yuzu or install a new GPU driver. The precompiled cache will then be compiled from scratch, causing a longer load time.
+
+Currently, the Vulkan renderer does not have a disk shader cache. This means that subsequent game loads will require the building of shaders each time. 
+
+IMPORTANT: Since the cache stores parts of the game, we don't condone sharing or downloading these, since it is considered piracy
