HEADED_GPU_PERFORMANCE_REPORT

Measured: 2026-07-15T17:48:54.064Z Commit: b5985f3 Base URL: http://127.0.0.1:3101/ Display: headed (:99) Software renderer detected: YES Verdict: NOT A GPU BASELINE — software renderer (SwiftShader/llvmpipe/etc.)

Notes

Headed Chromium with GPU-preferring flags.
PerfCollector only with ?perf=1; quality forced via ?quality=.
Prior headless ~9.6 FPS is labeled software/headless WebGL diagnostic baseline.
Host has NVIDIA GTX 1080 ×2, but Playwright Chromium in this coder/Xvfb session resolves WebGL to SwiftShader — numbers below are not a hardware GPU baseline.
For true GPU baseline: run PLAYWRIGHT_BASE_URL=… npm run perf:gpu on the presentation machine with a real DISPLAY and confirm renderer does not contain SwiftShader/llvmpipe.

Minimum FPS: 3.3
p95 frame time: 200 ms

Do not treat the above as live-demo GPU characteristics.
