El emulador FEX es utilizado por el proyecto Asahi para ejecutar en sistemas con chips ARM de Apple Silicon juegos de la biblioteca de Steam, compilados para la arquitectura x86_64. El c\u00f3digo del proyecto est\u00e1 escrito en C++ con inserciones en ensamblador y se distribuye bajo la licencia MIT.    <\/p>\n<p>Las bibliotecas necesarias para ejecutar aplicaciones x86 en un entorno ARM64 se conectan en forma de una capa de overlay con una imagen de sistema de archivos ra\u00edz (rootfs), proporcionada en formato SquashFS. Una capa as\u00ed permite evitar la creaci\u00f3n de un entorno chroot separado. La carga de las im\u00e1genes de rootfs ya formadas por el proyecto se realiza con la utilidad FEXRootFSFetcher.    <\/p>\n<p>Para acceder a las capacidades del entorno host, como herramientas para trabajar con sonido y gr\u00e1ficos 3D, se colocan en rootfs bibliotecas thunk, que traducen las llamadas a las bibliotecas y al c\u00f3digo en el lado del sistema host (por ejemplo, se pueden redirigir llamadas a OpenGL y Vulkan). Estas bibliotecas tambi\u00e9n pueden ser utilizadas en el lado del host para acceder al c\u00f3digo en el entorno invitado. Entre las bibliotecas disponibles para el desv\u00edo se encuentran: libEGL, libGL, libSDL2, libX11, libVDSO, libasound, libdrm, libfex_malloc, libvulkan, libwayland-client y libxshmfence.      <\/p>\n<p>En la nueva versi\u00f3n:  <\/p>\n<ul>\n<li class=\"l\"> Se ha realizado una importante optimizaci\u00f3n del compilador JIT, lo que ha permitido un aumento del FPS en el juego Cyberpunk 2077 del 38.9%, en Doom 2016 del 30.9%, en Stray del 25.2%, en Grim Fandango Remastered del 24.7%, en Teardown del 12.6%, y en God of War 2018 del 4.6%. Las principales mejoras se debieron a la optimizaci\u00f3n de la pila de llamadas y retornos (call-return), as\u00ed como a la implementaci\u00f3n en las bibliotecas wow64\/arm64ec del modelo de memoria TSO (Total Store Ordering), soportado en los CPU de Apple Silicon.      <center><img decoding=\"async\" alt=\"Lanzamiento del emulador FEX 2508, que permite ejecutar programas x86 en sistemas
