What is a Frame Rate Test?

A Frame Rate Test measures how many frames per second (FPS) your display, browser, and device can render in real time. Frame rate is one of the most important indicators of visual smoothness. The higher and more stable your FPS, the smoother motion appears on screen.

What is a good FPS for gaming?

For gaming, 60 FPS is considered the standard for smooth performance. Higher frame rates like 120 FPS and 144 FPS are preferred for competitive gaming. Esports players typically target 240 FPS or above for the fastest possible reaction time advantage.

What is the difference between FPS and Hz?

FPS (frames per second) measures the number of frames your GPU and browser can render per second. Hz (Hertz) measures the refresh rate of your monitor — how many times per second your screen updates the image. For the smoothest experience, your FPS should match or exceed your monitor refresh rate in Hz.

Is a browser frame rate test the same as an in-game FPS test?

No. A browser frame rate test measures the rendering performance of your web browser using the requestAnimationFrame API. In-game FPS reflects the full GPU workload of rendering a 3D game environment. However, a low browser FPS always indicates a real system issue such as hardware acceleration being disabled, GPU overheating, or high background CPU load.

1% Low FPS is the average of the worst 1% of all frames recorded during your test session. It reveals micro-stutters and frame spikes that your average FPS hides. If your Average FPS is 120 but your 1% Low is 40, your gameplay will feel smooth most of the time but will have sudden jarring stutters.

How do I improve my frame rate?

To improve your frame rate: enable hardware acceleration in your browser settings, close background tabs and applications, update your graphics drivers to the latest version, lower graphics settings such as resolution and shadows in games, disable browser extensions that interfere with rendering, and ensure your system is not thermal throttling by keeping it cool and well-ventilated.

Why is my FPS capped at 60 even on a 144Hz monitor?

If your FPS is capped at 60 on a 144Hz monitor, check these common causes: V-Sync may be enabled capping output to 60 FPS, your browser may have hardware acceleration disabled, your display cable may not support 144Hz (use DisplayPort or HDMI 2.0), or your monitor may not be set to 144Hz in Windows display settings.

Can I run a frame rate test on mobile (Android and iPhone)?

Yes. The frame rate test tool at frameratetest.net works on all mobile browsers including Chrome on Android and Safari on iPhone. Open the site in your mobile browser and tap Start Test. iPhones with ProMotion (iPhone 13 Pro and newer) can display up to 120 FPS. Most Android budget phones are capped at 60 FPS while flagship models support 90Hz or 120Hz.

Does the frame rate test collect or store my data?

No. All frame rate measurement happens locally in your browser using the requestAnimationFrame API. Nothing is recorded, stored, tracked, or sent to any server. Your FPS results are completely private.

What is frame time and why does it matter?

Frame time is the number of milliseconds it takes to render one individual frame. At 60 FPS, each frame should take 16.67ms. At 144 FPS, each frame takes 6.94ms. Consistent frame time means smooth visuals. If frame time spikes to 50ms or higher during a test, you will see a visible stutter even if your average FPS appears high.

Polling Rate Reference

Common Mouse Polling Rates and Response Times

Every polling rate has a corresponding response time. Here is the full comparison from 125 Hz to 8000 Hz so you know exactly what your reading means.

Polling Rate	Response Time	Use Case	Performance	CPU Load
125 Hz	8 ms	Basic office use, casual browsing	Low	Minimal
250 Hz	4 ms	General gaming, office work	Fair	Very low
500 Hz	2 ms	Competitive gaming, general gaming	Good	Low
1000 Hz	1 ms	Competitive FPS, esports standard	Excellent	Moderate
2000 Hz	0.5 ms	High-level esports, pro gaming	Very High	Noticeable
4000 Hz	0.25 ms	Pro esports, maximum precision	Ultra	High
8000 Hz	0.125 ms	Professional esports, max smoothness	Maximum	Very high

⚠️

Higher Is Not Always BetterA higher polling rate sends more data to your CPU every second. At 8000 Hz your mouse reports 8,000 times per second, placing significantly more load on your processor than 1000 Hz. For most gamers, 1000 Hz delivers the best balance of precision and CPU efficiency. Only move to higher rates if your system can handle it and sub-millisecond timing genuinely matters at your level of play.

How the Measurement Works This tool counts how many mousemove events the browser receives per second as you move your mouse. Each event corresponds to one position report from your mouse hardware. By counting events over a sliding window, we calculate your polling rate in Hz with high precision. Moving continuously gives the most accurate readings.

Accuracy and Expected Variance Minor fluctuations of 5 to 15 Hz around the true rated value are completely normal due to browser overhead and USB polling variance. For a 1000 Hz mouse, expect readings consistently in the 900 to 1050 Hz range during active movement.

Best results: Move your mouse in smooth circles for at least 10 seconds to get a stable average reading.

Step by Step

How to Use the Polling Rate Tester

Getting an accurate polling rate reading takes under 30 seconds. Follow these steps for the most reliable results.

Connect Directly Plug your mouse directly into a USB port on your computer. Avoid USB hubs as they can reduce the effective polling rate below your mouse's rated speed. Direct USB

Enter the Zone Move your mouse into the orange test zone above. Measurement begins automatically — no button press needed. Auto-start

Move Continuously Move your mouse in smooth circles inside the zone for at least 10 seconds to allow the tool to calculate an accurate average polling rate. Keep moving

Read Your Results Watch the live Hz number and mini chart update in real time. After 10 to 15 seconds, check the average reading — this is your actual polling rate. Live display

Compare Your Score Compare your average against the polling rate table. If your reading is lower than rated, check USB connection, mouse software settings, and hub usage. Diagnose issues

Adjust and Retest Change your polling rate in your mouse software, click Reset, and move again to confirm the change took effect. Iterate

Why Polling Rate Matters for Gaming

Your polling rate is one of the most underappreciated hardware settings in gaming. Here is why it makes a measurable difference.

Reduced Input Lag Every polling interval is a window where your movement goes undetected. At 125 Hz, your mouse waits up to 8 ms between reports. At 1000 Hz that wait shrinks to 1 ms — directly affecting whether your crosshair is on target when you fire.

Smoother Cursor Movement Higher polling rates produce more position samples per second, resulting in smoother, more precise cursor movement. A 1000 Hz mouse tracks micro-movements that a 125 Hz mouse misses entirely between polling intervals.

Better Aim Precision At low polling rates, fast flick movements can cause your cursor to skip over a target between intervals. At 1000 Hz and above, the shorter intervals allow precision targeting at high velocity to become significantly more consistent.

Verify Your Hardware Mice sometimes ship with polling rates lower than advertised, or performance can degrade due to driver issues. This tester gives you a real-world measurement so you can confirm your mouse is running at its rated speed.

How to Change It

How to Change Your Mouse Polling Rate

Changing your polling rate depends on your mouse type. Most gaming mice include companion software that handles this in seconds.

Gaming Mice with Software Brands like Logitech (G Hub), Razer (Synapse), Corsair (iCUE), and SteelSeries (GG) include companion software that lets you change polling rate from a dropdown. Open the software, find the report rate setting, and select your desired Hz. Changes take effect immediately.

Common brands: Logitech, Razer, Corsair, SteelSeries, ASUS ROG, Zowie, Glorious, Pulsar, Finalmouse

Physical Button or Budget Mice Some mice have a physical polling rate button on the underside. Pressing it cycles through available Hz settings. For non-branded mice, the open-source HidUsbFx2 tool for Windows can force higher polling rates — though this requires careful setup and administrator access.

Note: Not all mice support rates above 125 Hz at the hardware level. Check your mouse specifications before attempting to change the setting.
