FAQ
Frequently Asked Questions
Quick answers to what gamers and repair professionals ask most.
Our GPU tester measures frame rate, rendering stability, texture fill rate, triangle throughput, and shader performance. It also reads your GPU renderer name, vendor, WebGL version, and supported extensions directly from your browser.
Yes. The tool works with any GPU that supports WebGL, including integrated Intel and AMD graphics found in laptops. Results will naturally be lower than a dedicated gaming GPU and the tool rates performance accordingly.
Google Chrome or Firefox give the best results. Both support WebGL2 which powers all the tests. Edge also works. Safari has limited WebGL2 support so some tests may produce lower scores on Mac.
Some browsers anonymize GPU information as a privacy measure. If you see a generic renderer name, check your browser settings or try a different browser. Chrome and Firefox usually expose the full GPU name.
Not exactly. Browser-based GPU tests use WebGL which runs through the browser sandbox, so scores are lower than native benchmarks. This tool is designed for quick health checks and comparing relative performance, not replacing a full native benchmark suite.
Completely. Every test runs locally inside your browser. No GPU data, scores, or hardware information is uploaded to any server. PadProTools never collects any personal or hardware data from users.
