Shader Cache Ryujinx ((exclusive)) Site

Your graphics card driver (Nvidia, AMD, or Intel) also keeps its own cache of the compiled shaders. This acts as a secondary layer of acceleration. How to Enable and Optimize Shaders in Ryujinx

If you experience visual artifacts or unexpected crashes, the cache may be corrupted. In these cases, deleting the existing cache files and allowing the emulator to rebuild them can resolve the issue. System-Wide Settings: For NVIDIA users, increasing the "Shader Cache Size" to 10GB or 100GB NVIDIA Control Panel

You do not need to clear your cache frequently. However, you should purge it if you experience:

If you're tired of shader compilation stutter in Ryujinx, you can download or share pre-built shader caches. shader cache ryujinx

As you play a game, your shader cache grows. Over time, the stuttering naturally decreases until it disappears completely once most of the game's assets have been loaded at least once. Key Features of the Ryujinx Shader Cache

Sometimes, after a Ryujinx update or a game update (e.g., from Version 1.1.0 to 1.2.0), your old shader cache becomes incompatible. Symptoms include:

Ryujinx utilizes two distinct layers of shader caching to optimize your performance. 1. The Ryujinx Shader Cache (PPTC)

Strange flashing lights, missing textures, or neon colors after updating Ryujinx or your GPU drivers. Your graphics card driver (Nvidia, AMD, or Intel)

Because building a shader cache from scratch requires playing through stutters, a common trend among users is searching for complete, pre-compiled shader caches online.

Shader caching requires constant reading and writing to your storage drive. Running the emulator from a fast Solid State Drive (SSD) instead of a traditional Hard Disk Drive (HDD) ensures that shader files load fast enough to prevent noticeable hitching.

| Game Title | Approx. Shader Count | Impact of Cache | | :--- | :--- | :--- | | | 35,000 - 45,000 | Mandatory. Unplayable without it on low-end CPUs. | | Xenoblade Chronicles 3 | 18,000 - 22,000 | Massive improvement. Removes 99% of stutter. | | Red Dead Redemption | 8,000 - 10,000 | High impact. Reduces audio crackling during shader compilation. | | Bayonetta 3 | 12,000 - 15,000 | Medium impact. Mostly eliminates scene transitions. | | Super Mario Wonder | 3,000 - 4,000 | Low impact (game is light), but still nice for 60 FPS mods. |

This is normal behavior. Upgrading graphics drivers clears your GPU's internal Vulkan pipeline cache. Ryujinx must re-cache these pipelines. The stuttering will be brief and will subside after a few minutes of gameplay. If you want to optimize your setup further, let me know: What are you currently using?

OpenGL is an older legacy backend. It compiles shaders synchronously. If a new shader appears, the entire game engine halts until it is processed. This results in heavy, frequent stuttering. OpenGL should only be used if Vulkan crashes on your specific hardware. How to Optimize Ryujinx Shader Settings

allow the game to keep running while shaders build in the background, further reducing visible lag.

The first time you encounter an object or effect in a game, Ryujinx compiles it on the fly and saves it to a local file. This is when stuttering is most noticeable.
