Every RX 6000 loss whose pass marks named a pass was in one that starts with a native mesh draw, on every version from 0.6.0 to 0.9.2 and with every other setting tried each way; RDNA 1 cards on the same driver draw through the fallback and RDNA 3 and 4 on AMD's other driver draw natively, and neither has such a report. That the native mesh path is the cause is not shown. The decision moves into vk_mesh_path.h with a test of each device kind and setting; has_mesh_shader keeps saying what the hardware has, so the recorder thread and the low-end card test do not change. On those cards no native mesh pipeline is built any more: the seed list and the boot prewarm skip them. The early tail stays off with the fallback, a combination never measured. The fatal line names the mesh path, and NX2NAVI_VK_NOOPT's default applies with mesh_fallback = 0 alone. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
