How to use the FPS test
- Pick a load level. Low is easy on any device. Medium is a fair, balanced test. High and Extreme push stronger hardware and make ghosting easier to spot.
- Choose a duration. A short 15 second run gives a quick reading. Longer runs of 30, 45, or 60 seconds give a steadier average and a more reliable 1% low.
- Start the test. The animation runs while the dashboard updates live with your frame rate and other metrics.
- Read your results. When the run ends you get your final average, min, max, and 1% low FPS, plus an estimate of your refresh rate.
What each metric means
The dashboard shows the same numbers a serious frame rate test would, so you can judge real smoothness, not just a single headline figure.
- Frame Rate
- Your live FPS right now. This is the number most people mean when they talk about FPS.
- Refresh Rate
- An estimate of your display Hz from the fastest stable frame rate seen. Useful as a quick Hz test.
- Average FPS
- The mean frame rate across the whole run. A good overall measure of performance.
- 1% Low
- The average of your slowest 1% of frames. This is where stutters hide, so watch it closely.
- Min and Max FPS
- The lowest and highest single frames. A big gap points to uneven pacing.
- Pixels Per Frame and Per Sec
- How much the tool draws each frame and each second, a simple view of how hard your device is working.
Using this as a refresh rate test and Hz test
Most browsers cap animation at your monitor refresh rate. That makes this a handy refresh rate test: if your frame rate settles near a clean value like 60, 120, or 144, that is a strong hint about your panel Hz. For the best Hz test result, close other heavy tabs and run the test on the display you want to check.
Running a ghosting test
Ghosting is the faint trail some panels leave behind moving objects. To run a quick ghosting test, start the FPS checker on the High or Extreme load and look at the edges of the moving dots. Crisp edges mean a fast pixel response. A visible smear means slower response and more ghosting, which can blur fast action in games.
What is a good FPS for gaming?
The right frame rate depends on what you play and the screen you play on. There is no single magic number, but these ranges give you a sense of where you stand.
| Frame rate | How it feels | Best for |
|---|---|---|
| 30 FPS | Playable, but motion looks a little choppy. | Slower single-player and strategy games. |
| 60 FPS | Smooth and responsive. The common target. | Most games on a 60Hz screen. |
| 120 FPS | Very fluid, with crisp fast motion. | Action games on a 120Hz display. |
| 144 FPS and up | Buttery smooth with the lowest input lag. | Competitive shooters on a high refresh monitor. |
Your frame rate can never look smoother than your monitor allows. A steady 60 FPS on a 60Hz screen feels great, while chasing 200 FPS on the same panel adds little you can see. To get the full benefit of a high frame rate, you also need a high refresh rate display.
Why does my frame rate keep dropping?
A frame rate that jumps around usually points to something competing for your device's resources. Background apps, browser tabs, and downloads all steal performance. On a laptop, battery saver settings often cap the frame rate to save power, so plugging in can help. Heat is another common cause: when a device gets hot it slows itself down to cool off, which shows up as a falling frame rate over a longer run. If your average looks fine but the 1% low is poor, that points to short stutters rather than a steady drop.
- Close background tabs. Other heavy pages steal frames and lower your score.
- Plug in your laptop. Battery saver modes often cap performance and the frame rate test.
- Run it more than once. A couple of runs give a steadier average and 1% low.
- Match the display. Run the test on the screen you actually want to check.
- Use full screen. A larger test area gives the FPS tester more work and a clearer reading.
Frequently asked questions
What does this FPS test measure?
This FPS tester measures how many frames per second your browser can draw on your screen. It reports your live frame rate, your average, minimum, and maximum FPS, your 1% low, and an estimate of your monitor refresh rate. It also shows pixel throughput so you can see how hard your device is working.
How is this different from an in-game frame rate test?
A game measures the FPS of that specific game on your full system. This frame rate test measures what your browser and display can do with a steady animation. It is a quick, fair way to compare devices, check a new monitor, or confirm a setting changed something, without installing anything.
What is a 1% low and why does it matter?
The 1% low is the average frame rate of your worst 1% of frames. A high average with a low 1% low means you get stutters even when the number looks good. Smooth gameplay needs both a high average and a 1% low that stays close to it.
How does the refresh rate and Hz test work?
The tool watches the fastest stable frame rate your browser reaches and matches it to the nearest common panel value, such as 60Hz, 120Hz, or 144Hz. Most browsers cap animation at your display refresh rate, so this refresh rate test gives a solid estimate of your monitor Hz without extra software.
How do I run a ghosting test?
Start a test and watch the moving objects closely. On a slower panel you may see a faint trail behind each object, which is ghosting. A fast panel keeps the edges crisp. For the clearest ghosting test, use the High or Extreme load so there is plenty of motion to judge.
Why is my frame rate capped at 60?
Browsers sync animation to your display refresh rate. If you see a clean cap near 60, your monitor or current mode is likely 60Hz. On a 120Hz or 144Hz display the FPS checker should climb well past 60 once the browser is allowed to run at the higher rate.
