Eftersom GPU:n VideoCore IV, som finns i \u00e4ldre modeller av Raspberry Pi, inte har tillr\u00e4ckliga resurser f\u00f6r att fullt ut st\u00f6dja Vulkan, implementerar drivrutinen endast en delm\u00e4ngd av Vulkan API som inte t\u00e4cker hela standarden, men f\u00f6rs\u00f6ker f\u00f6lja den i den utstr\u00e4ckning h\u00e5rdvaran till\u00e5ter. \u00c4nd\u00e5 \u00e4r den tillg\u00e4ngliga funktionen tillr\u00e4cklig f\u00f6r m\u00e5nga program och spel, och prestandan \u00f6vertr\u00e4ffar markant OpenGL-drivrutiner, tack vare mer effektiv minneshantering, flertr\u00e5dad bearbetning av GPU-kommandon och direkt kontroll \u00f6ver GPU-operationer. Drivrutinen st\u00f6der \u00e4ven funktioner som MSAA (multisample anti-aliasing), l\u00e5gniv\u00e5-shaders och prestanda-m\u00e4tare. Bland begr\u00e4nsningarna kan n\u00e4mnas bristen p\u00e5 st\u00f6d f\u00f6r GLSL-shaders, som f\u00f6r n\u00e4rvarande inte \u00e4r tillg\u00e4ngliga i detta utvecklingsskede.<\/p>\n

Samma f\u00f6rfattare publicerades<\/a><\/noindex> Quake 3-spelport f\u00f6r Raspberry Pi, som fungerar som en demonstration av de nya drivrutinsfunktionerna.
