Yuzu developers introduced a feature called "Async Shader Compilation" (Settings > Graphics > Advanced). This changes how shader caches work.
| Feature | Traditional Cache | Async Compilation | | :--- | :--- | :--- | | Stutter | None (once cached) | None | | Visuals | Perfect | Objects may be invisible for 1-2 seconds while shader compiles | | CPU Usage | High during compilation | Low | | Risk | Slow initial load | Can crash on AMD GPUs |
If you hate stuttering but don’t mind seeing an invisible enemy for one second, enable Async. If you want visual perfection, use a full shader cache.
To understand the "work" of a shader cache, you first need to understand the fundamental disconnect between PC hardware and Nintendo Switch hardware. yuzu shader cache work
Yuzu introduced a feature called asynchronous shader compilation (async). Instead of freezing the game while compiling a shader, Yuzu draws nothing for that object for a split second — maybe a missing texture or invisible enemy — but keeps the framerate smooth.
“It’s a trade-off,” Mia explained on her blog. “Async removes stutter but can cause graphical glitches. The shader still gets cached, so the glitch only happens once per shader.”
For purists, synchronous compilation (with a full shader cache) was still the gold standard: no stutters, no glitches. Yuzu developers introduced a feature called "Async Shader
If you are still experiencing stuttering despite the cache, one of these three issues is likely at play:
Over time, as you play, your personal cache grows. The first hour of a game like Bayonetta 3 is a stutter-fest. After 10 hours, it is mostly smooth because Yuzu has seen almost every visual effect.
This is where the Shader Cache comes in. If you are still experiencing stuttering despite the
The concept is simple: Why compile the same shader twice?
The first time Yuzu encounters a specific Switch shader, it compiles it for your PC. Once that hard work is done, Yuzu saves (caches) that compiled file on your storage drive. The next time you boot the game, Yuzu checks its cache. If the shader is already there, it skips the compilation entirely and loads the pre-compiled file instantly.
This turns a potentially stuttery experience into a seamless one. Once a cache is built (or downloaded), games play as if they were native PC ports.
