Unreal Engine PSO Caching solution can help resolve stuttering caused by shader compilation on Android devices but documentation page can be confusing for android developers as its not really simplified for android platforms thus in this tutorial we will go through the process of how we can add PSO Caching to our Android Project.
Also, Please keep in mind that PSO Caching does come with the drawback of increasing the first boot up time noticeably on mobile devices.

Hello, Did you find solution to build Android PSO Caching in UE 5.4?
I find that *.upipelinecache create only on Vulkan api, dont work on openGl ES3.2
