GPU Test & Graphics Benchmark Guide
Check graphics performance concepts and learn how browser-based GPU diagnostics work.
How to use this test
Start the test, keep the tab visible and use the same input setup you use for games. For performance tests, pick the load level before starting so the sample is measured under a consistent workload.
How the measurement works
Browser graphics checks depend on available APIs and reported rendering capability.
How to interpret results
Use averages and lows together. Peaks show what the browser can briefly hit, while slower samples reveal stutter, input delay or load spikes that matter more during real play.
Troubleshooting tips
Close overlays, streaming tools and heavy tabs, plug in controllers before loading the page and keep the browser unthrottled by battery saver or background-tab behavior.

A web page cannot replace manufacturer GPU benchmark software.

Use the same browser, device, settings and test conditions for each run. Repeat the measurement several times and compare a typical result rather than relying on a single unusually high or low value.
