About Volume Shader

Volume Shader is a browser GPU test. You open a page, start a WebGL scene, and watch live frames per second while a shader ray marches a 3D volume. The main scene is a Mandelbulb. RankAlgos Tech (Private) Limited publishes the site. The live canvas is Run Volume Shader.

People use it to see whether a phone or computer holds a smooth frame rate under a heavy graphics load. They compare two devices in the same browser. They record a short clip. The test does not score CPU, storage, or battery wear. It does not certify that a phone is genuine.

The rendering idea is volume ray marching. Each pixel walks a ray through a 3D field until it hits a surface. More iterations mean more GPU work. That is why Simple through Extreme change the score, and why a hot device looks slower than a cool one. For the kernel, the name, and Volume Shader BM, read What is Volume Shader.

You can also run a 3D rendering test, a shader test, and a VRAM test. Those loads cover raster draw, fragment math, and texture sampling. A GPU test overview covers FPS, vsync, and how a browser result differs from Furmark or GPU-Z.

Public WebGL demos popularized this look years ago, often found through GitHub Pages. You do not need GitHub to run the test here. Open the canvas on this site. You get a start button, complexity levels, fullscreen, and the extra GPU tests.

Optional native apps are on Google Play and the App Store. This site is Volume Shader on volumeshader.com.

The test runs on your device. We do not upload FPS unless you choose to screenshot or share it. Questions go to Contact. Common answers are in the FAQs.
