Frequently Asked Questions
Everything you need to know about our FPS checker and FPS test tool.
An FPS checker measures frames per second, a useful indicator of how smoothly a browser or application is producing visual updates. Our free online tool uses the browser's requestAnimationFrame API to measure the current rendering path without installing software. Keep the tab visible and repeat the test when comparing results.
The test counts rendered animation callbacks using the browser's native requestAnimationFrame API. That makes it useful for checking the current browser and display path, but it is not a game benchmark or a calibrated display measurement. Keep the tab visible, repeat the run, and record the conditions when comparing results.
A good FPS score depends on your use case. For general web browsing, 60 FPS is ideal and matches most standard monitor refresh rates. Gamers typically aim for 120+ FPS, especially on high refresh rate displays (144Hz or 240Hz). Anything below 30 FPS will feel noticeably choppy.
Several factors can cause lower-than-expected FPS results: heavy background processes consuming CPU/GPU resources, browser extensions running scripts, disabled hardware acceleration, outdated graphics drivers, or thermal throttling on laptops. Try closing other applications and running the FPS test again for a cleaner measurement.
Yes, our FPS checker is fully responsive and works on all modern mobile devices including iPhones, Android phones, and tablets. Mobile devices typically display 60 FPS, though newer devices with ProMotion or similar technology can achieve 90-120 FPS. The free online FPS test adapts to any screen size.
No downloads are required. The FPS test runs in your web browser. Open the test, keep the tab visible, click 'Start Test,' and review the average, minimum, maximum and frame-time history. Close heavy background work before comparing two runs.
To improve your FPS: close unnecessary browser tabs and applications, enable hardware acceleration in your browser, update your graphics drivers, lower your display resolution if needed, and disable heavy browser extensions. For gaming, reduce in-game graphics settings and ensure your system meets the recommended requirements.
While our FPS checker measures your browser's frame rate rather than in-game FPS, it is an excellent indicator of your system's baseline rendering capability. If your browser achieves high FPS, your system is likely capable of smooth gaming. For in-game FPS, use the built-in FPS counters in your games or Steam overlay.
