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
Recommended GPU Testing Software
For deeper hardware level testing, use these tools alongside our browser tests:
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.
