WebGL Support Test

Inspect the graphics path your current browser exposes before running a heavy volume shader benchmark. The report stays local and shows WebGL support, WebGL2 support, renderer strings, precision, limits, and extensions.

Test notes

  • Renderer strings can vary by browser, privacy settings, driver, and GPU backend.
  • WebGL2 support is the best first check before using the editor or advanced presets.
  • Copy the JSON report when you need to compare two browsers or devices later.
