The Raspberry Pi Foundation has introduced Vulkan 1.1 compliance to the Raspberry Pi 4 family of single-board computers (SBCs). Support for Vulkan 1.1.1 brings about a noticeable GPU performance uplift for the already powerful SBCs.

Wait huh? So Pi4 doesn't run UE4, and now it doesn't run UE4, 60% faster? Which other 3D engines doesn't it run faster? Do any of these performance boosts matter at all?
Does this mean anything to someone just running X or Wayland? Which OSes will have Vulkan 1.1?
What they mean by that is most UE4 games can't be run on a Raspberry Pi device at playable speeds simply because they're made for more powerful PC's that aren't ARM PC's. But I presume this Vulkan update will allow Pi users to do a whole lot more in areas where the Pi is capable, such as emulation and older games that might need a graphics boost. I'm sure we will all find out soon!
