“Khronos has just granted Vulkan 1.1 conformance to Raspberry Pi 4 SBC, and following the implementation of various optimizations and new features such as geometry shaders, the v3dv Mesa driver delivers up to 60% higher GPU performance in Unreal Engine 4.”
A two-year-old board got up to 60% faster graphics from a software update. The driver is open source and already merged upstream in Mesa. Most hardware gets slower with every update. The cheapest computer around keeps getting better.
