WebGL Test

WebGL lets pages draw with your graphics hardware. This test confirms it works, shows what the browser reports about the renderer, and runs a small animation so you can see it is actually rendering.

Averaged over the last second. Limited by your display refresh rate; not a benchmark.

Checking WebGL support

Runs entirely in your browser. Nothing is uploaded or stored.

How to use

  1. Read the support lines for WebGL and WebGL 2.
  2. Check the renderer and vendor. On some browsers these are generic on purpose.
  3. Watch the animation. A steady frame rate near your refresh rate is a good sign; a very low rate suggests software rendering.

What this test can detect

  • Whether hardware-accelerated graphics are available to the browser.
  • The graphics driver or GPU the browser is using, where it is exposed.
  • Software rendering fallbacks that make 3D content slow.

Important

  • Renderer names are hidden or generalized by some browsers for privacy.
  • The frame rate is limited by the display refresh rate and by the browser. It is not a benchmark score.
  • This is a compatibility check, not a graphics performance test.
