This fps test counts the frames your browser renders every second and keeps the slowest and fastest one-second values, the session average and the 1% low, so you can see both how fast and how evenly frames arrive.

Reading your fps test results

Current FPS

Frames drawn in the last second.

Average

All frames since start or reset divided by the time.

Min and max

The slowest and fastest one-second readings.

1% low

The frame rate during the slowest 1% of frames. Good for spotting hitches.

Target FPS for games, video and browsing

24 fps

The film standard. Fine for movies, but looks choppy in fast games.

30 fps

Common on older consoles and phone power-saving modes. Playable, not smooth.

60 fps

The baseline for most monitors, laptops and phones. Smooth for everyday use.

120 fps

Used by many phones, tablets, TVs and consoles. Noticeably smoother scrolling and motion.

144 fps

A popular gaming monitor rate. Each frame lasts about 6.9 ms.

240 fps

Esports monitors. About 4.2 ms per frame, so motion is very fluid.

How to test on PC, Mac, phone and console browsers

PC and Mac: close other heavy apps, open the page in Chrome, Edge, Firefox or Safari and leave it in front for 30 seconds. Phone and tablet: turn off low power mode and keep the screen awake. Consoles and TVs: the built-in browser works if it supports modern JavaScript, but many are capped at 60 Hz.

How to fix low FPS

Check the display setting

Windows: Settings → System → Display → Advanced display. macOS: System Settings → Displays. Pick the highest refresh rate your screen offers.

Use a performance power mode

Laptops and phones often limit frame rate on battery. Plug in or switch to a high performance profile, and turn off low power mode.

Update graphics drivers

Install the latest driver from NVIDIA, AMD or Intel, or update your phone and browser.

Turn on hardware acceleration

In Chrome or Edge, enable “Use graphics acceleration when available” and restart the browser.

Close heavy apps and tabs

Background apps, video calls and many tabs compete for the same graphics chip.

Use the right cable and port

High refresh rates need DisplayPort or a recent HDMI version, and the port on the graphics card, not the motherboard.

What it measures

This page measures what your browser actually draws, using requestAnimationFrame. Browsers cap their frame rate at the refresh rate of the display, so the Hz value is an estimate of the rate your screen is running at right now, not the maximum it supports. It cannot measure response time (GtG), input lag, screen tearing or whether the panel itself skips frames; those need special hardware or a camera.

FPS FAQ

Does this measure FPS in my games?

No. It measures the frame rate of this browser tab. Use an in-game counter or overlay for game FPS. It is still a good quick check of your display setting and system smoothness.

Why does FPS drop when I switch tabs?

Browsers pause or slow animation in background tabs. The page ignores those gaps, but switch back and press R to reset for clean numbers.

Can FPS go above my refresh rate here?

No. Browsers draw at most once per refresh, so the result is capped at your display’s current Hz.
