GPU Test — WebGL Capabilities & Performance

Check your device’s GPU and WebGL capabilities. This test identifies your graphics renderer, lists supported WebGL extensions, and runs performance benchmarks to measure rendering speed.

GPU test

GPU & WebGL Diagnostics

Test your device GPU capabilities via WebGL. Get renderer details, extension info, and a rendering performance benchmark. Nothing leaves your device.

Before you start

  • This test creates a hidden WebGL canvas to read GPU parameters and run a short benchmark.
  • No images or video are captured — only technical GPU info is read via WebGL APIs.
  • The benchmark renders rotating triangles to measure rendering performance.
  • All data stays in your browser. Nothing is uploaded.

WebGL reports are limited to what the browser exposes. Some drivers hide or report inaccurate information. Results are indicative, not definitive.

Browser limitations
  • • WebGL availability depends on browser, OS, and GPU driver.
  • • Some browsers block hardware acceleration in certain contexts.
  • • Renderer names may be generic (e.g. "SwiftShader") when hardware acceleration is off.
  • • Performance results vary with system load and thermal state.
