Always use Vulkan for shader caching unless you have a specific compatibility issue. Vulkan’s pipeline cache is more efficient, and while the stutters are still there, they are less violent than on OpenGL. The Golden Rule: Never Delete Your Cache Mid-Game Yuzu stores your shader caches in the following directory: C:\Users\[YourUserName]\AppData\Roaming\yuzu\shader\

If you delete it, Yuzu forgets every shader it ever learned. You will experience stuttering for every single visual effect from scratch, as if you are playing the game for the first time again.

Every new area, every new enemy, every new particle effect introduces new shaders. No matter how fast your SSD or how many cores your CPU has, the first time you encounter a visual effect in an emulator, there will be a tiny compilation stutter. The only way to eliminate stuttering entirely is to have a complete shader cache before you start playing. Yuzu supports two primary graphics APIs: OpenGL and Vulkan. They handle shaders very differently.
