El controlador es adecuado para todos los modelos de placas Raspberry Pi lanzados antes de la llegada de la Raspberry Pi 4, \u2014 desde 'Zero' y '1 Model A' hasta '3 Model B+' y 'Compute Module 3+'. El controlador fue desarrollado por Martin Thomas (<noindex><a rel=\"nofollow\" href=\"https:\/\/twitter.com\/0martint\">Martin Thomas<\/a><\/noindex>), un ingeniero de NVIDIA; sin embargo, el desarrollo se llev\u00f3 a cabo como un proyecto personal, no relacionado con NVIDIA (el controlador fue desarrollado durante los \u00faltimos dos a\u00f1os en su tiempo libre). El c\u00f3digo <noindex><a rel=\"nofollow\" href=\"https:\/\/github.com\/Yours3lf\/rpi-vk-driver\">se distribuye<\/a><\/noindex> bajo licencia MIT.<\/p>\n<p>Dado que las capacidades del GPU VideoCore IV, que equipan los modelos antiguos de Raspberry Pi, no son suficientes para una implementaci\u00f3n completa de Vulkan, el controlador implementa solo un subconjunto de la API Vulkan, que no abarca todo el est\u00e1ndar, pero intenta seguirlo tanto como permite el hardware. Sin embargo, la funcionalidad disponible es suficiente para muchas aplicaciones y juegos, y el rendimiento supera notablemente a los controladores OpenGL, gracias a una gesti\u00f3n de memoria m\u00e1s eficiente, procesamiento de comandos en m\u00faltiples hilos y gesti\u00f3n directa de las operaciones del GPU. El controlador tambi\u00e9n soporta capacidades como MSAA (Multisample anti-aliasing), sombreadores de bajo nivel y contadores de rendimiento. Entre las limitaciones se destaca la falta de soporte para sombreadores GLSL, que a\u00fan no est\u00e1n disponibles en esta etapa del desarrollo.<\/p>\n<p>El mismo autor <noindex><a rel=\"nofollow\" href=\"https:\/\/github.com\/Yours3lf\/vkQuake3\/releases\/tag\/v1.0\">publicado<\/a><\/noindex> puerto del juego Quake 3 para Raspberry Pi, que act\u00faa como una demostraci\u00f3n de las capacidades del nuevo controlador.
