Understanding Browser-Based Testing

While our tests provide valuable insights, browser-based testing has some limitations:

  • Cannot measure actual GPU temperature
  • Limited to WebGL/WebGPU performance metrics
  • Results vary by browser and drivers
  • Complements desktop testing tools
  • Focuses on web graphics performance

Frequently Asked Questions

Yes, our browser-based tests are safe as they operate within browser limitations. Modern GPUs have built-in thermal protection. For desktop tools, always monitor temperatures.

For browser-based tests, 1-5 minutes per test is sufficient. For hardware stability testing with desktop tools, 15-30 minutes is recommended.

Scores above 80 indicate excellent performance. 60-80 is good for most use cases. Below 60 may indicate issues or an older GPU.

Yes! Our tests are fully responsive and work on smartphones and tablets with WebGL support.
