I'm using the igpu in a ryzen 4800u cpu. I ran the binary extracted from the appimage (`--appimage-extract`), but vulkan failed to be detected and 0ad fell back to gl. I also built latest git (48d13b) on my own laptop. Vulkan renderer worked fine in 0ad in this build. (No errors and userreport_hwdetect file showed lots of "VK_" .)
