Stage 11 of the wgpu port. WgpuViewportWindow gains setBenchmarkFrames(N); the minimal driver wires it to a --benchmark N flag. Renders N frames after a 5-frame warmup, yaw-sweeping the camera at 0.5°/frame, captures per-frame wall time with QElapsedTimer (cull + encode + present), and prints avg/median/p1/p99 + last-frame stats in the same line format as IfcViewerMinimal so a script can diff them line for line. Per-frame stats (visible_objects, visible_triangles, sub_draws) are now summed in render() from m.mesh_draws. hiz_rej reports 0 until stage 7 adds HiZ occlusion. Verified on basic.ifc (3 instances): wgpu 11.68 ms avg vs GL 11.75 ms avg — same scene, same camera sweep, same window size. Noise-level delta as expected on a tiny scene; the interesting comparison is on real BIM corpora once you bake them to v13 sidecars. Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
