Show HN: Free Volume Shader BM – a browser-based GPU performance benchmark

I built a free tool called Volume Shader BM. It’s a real-time graphics GPU performance benchmark that runs entirely in the browser — no installs, no drivers.

It uses shader-based ray marching (Mandelbulb scenes) to measure FPS, frame time, and stability across GPUs. You can tweak iterations, step size, resolution, and share reproducible results.
