Frequently Asked Questions

An FPS checker is a tool that measures your frames per second, which indicates how smoothly your screen renders visual content. Our free online FPS checker uses your browser's requestAnimationFrame API to deliver accurate real-time measurements without any software installation.

Our FPS test is highly accurate because it measures actual rendered frames using the browser's native animation API. The results reflect your true frame rate as experienced on screen, accounting for your hardware, browser, and current system load. It provides the same measurement method used by professional web performance testing tools.

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. Our FPS test runs entirely in your web browser. Simply navigate to the test section, click 'Start Test,' and you will see real-time frame rate measurements instantly. This is what makes it the most convenient free online FPS checker available.

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.
