Browser display performance suite
Online FPS Test for Frame Time and Display Performance.
Test your FPS, refresh rate, frame time, screen resolution, and display performance online. FPS Test is built for gamers, monitor buyers, competitive players, and anyone checking browser smoothness without installing software.
Method
How this browser FPS test works
The test runs a live canvas animation and samples frame intervals from the browser's animation loop. Those intervals are converted into current FPS, average FPS, frame time, a stability score, and a dropped or stuttered frame estimate.
This helps users check browser smoothness, display performance, screen behavior, and common motion issues. It is a practical diagnostic tool, not a direct GPU, CPU, game, or hardware benchmark.
Results are generated in the active browser tab using requestAnimationFrame timing. For cleaner comparisons, keep the tab focused, avoid resizing the window during a run, and compare multiple runs under the same power, browser, and display settings.
Cleaner results
Run the test under stable conditions
Keep this browser tab focused while testing.
Close heavy apps, downloads, and background game launchers.
Turn off battery saver or low-power mode.
Avoid resizing the window during the test.
Run for 15 to 30 seconds before trusting the average.
Compare multiple runs when diagnosing stutter.

What browser FPS can and cannot tell you
Browser timing depends on the active tab, OS scheduling, display mode, refresh-rate settings, power settings, browser throttling, and connected displays. The results are best used as a consistency and smoothness check.
In-game FPS can differ because games render different workloads and use engine-specific counters. Use FPS Test to check browser frame time, display smoothness, and troubleshooting signals, then compare game counters only as separate signals.

FAQ
FPS Test Questions
What does this FPS test measure?
It measures browser animation frame timing with requestAnimationFrame and turns those samples into FPS, frame-time, stability, and stutter estimates. The wider FPS Test suite is built around FPS, refresh rate, screen resolution, and display performance checks.
Is this the same as in-game FPS?
No. This is a browser-based estimate for display and animation smoothness. In-game counters measure a specific game engine, graphics settings, driver stack, and hardware workload.
How do I get a cleaner result?
Close heavy apps, keep this tab focused, avoid resizing the window during the test, disable battery saver, and run the test for at least 15 to 30 seconds.
Can a browser test prove my monitor refresh rate?
It can show useful frame timing behavior, but browser scheduling and OS settings can affect the result. Use it as a practical consistency check, not a lab-grade instrument.
