Gnome Horde runs under Android on a consumer device available now on the market; it uses the latest prototype Vulkan API driver for PowerVR GPUs (final performance may differ).
On the left-hand side of the video, we are showing Vulkan and on the right we have OpenGL® ES 3.0. We have attempted to ensure both versions run equivalent code and both run without extensions. The demos are not using instancing either, each draw call could be a different piece of geometry with a different material or texture and the CPU performance would be very similar.
