{{Main|Shader caches}}
When your game is loaded, check for its ID on the title bar in front of "SaveDir:" and note it down. The directory where transferable shader caches are stored is <code>.\Cemu\shaderCache\transferable</code>. They're generated the first time you play through a game and at that time cause noticeable stuttering. You can download a complete cache from places like [https://chriztr.github.io/cemu_shader_and_pipeline_caches/ here] and rename them to match your game version's ID to spare yourself most of that unpleasant experience. Just keep in mind that shader caches from versions older than 1.8.0 are incompatible with later versions of Cemu.

{{Main|Shader caches}}
Shaders are normally cached as you play the game. This can cause a lot of stutters and slow the game down. However, as of version 1.19.0, Cemu added support for Asynchronous Shader Compiling on their Vulkan API which can make shader compiling near instantaneous on modern hardware, so try enabling that before hunting for shader caches.

Cemu for Android is an experimental fork created by the user SSImco. It is still in beta and not officially supported. While it allows some users to run Wii U games on Android devices, the performance and compatibility can vary greatly depending on the device. As of now, it is primarily intended for testing and development purposes.

Additionally, a version created by the user [https://github.com/XForYouX/Cemu-Android XForYouX], who forked SSImco's code and made his own modifications, also exists; however, XForYouX only provides the compiled APK without releasing the source code, which has raised concerns regarding transparency and trustworthiness.
