What Is Frame Rate, and Why Should You Care?

Before you can speed up your screen, it helps to know what is actually moving. Let us slow it down and look at how every smooth moment on your display is built, one tiny frame at a time.

One Frame at 60 FPS
16.67ms
That is how much time your GPU has to draw every single image. Less than the blink of an eye.
One Frame at 240 FPS
4.17ms
Four times faster. The reason competitive players can see and react to motion before others do.
Components per Frame
5parts
Input, CPU, GPU, memory, and display all have to cooperate. Any one of them can slow you down.

Look at your screen right now. It feels like a single, continuous image. It is not. Your display is redrawing the entire picture dozens of times every second, and each of those rapid redraws is a frame. The speed at which they happen is your frame rate, measured in FPS (frames per second).

More frames per second means less time between updates, and your brain stops noticing the gaps. At 24 FPS you get the cinematic feel of film. At 60 FPS, scrolling and motion feel smooth and snappy. At 144 FPS, fast camera turns stay crisp and your hands feel like they are moving the second you think about it. Lower numbers look choppy, and in fast games, choppy means slow reaction time.

Here is the part most people miss. Your FPS does not come from one part of your computer. It is a team effort. Your GPU has to render fast, your CPU has to keep up, and your monitor has to actually show what they produce. The weakest member of that team sets the ceiling for everything.

Quick fact

Movies have looked great at 24 FPS for over a century. But movies are not interactive. The moment you add a mouse or a controller, every dropped frame becomes a delay you can feel. That is why games need so much more.

What FPS tells you
The big number is how many frames per second your device is drawing right now. Higher is smoother. Most modern monitors top out at 60, 144, or 240.
Why 1% Low matters
Averages hide problems. The 1% Low value shows your worst frames. If it is much lower than your average, you are experiencing stutters even when things look fine on paper.
Reading stability
Above 90% means your frame pacing is great. Below 70% and you will feel jitter even at high average FPS. This is the metric serious players quietly obsess over.

You are running faster than 78% of devices

Averaging 142 FPS at 92% stability puts you firmly in the upper tier. Your GPU has clear headroom and your display is being used to its potential. If you have a 144Hz monitor or higher, you are getting close to a perfect match.

What this means for you
Your 144Hz display is being driven at full refresh. No frames are getting wasted, and your hardware is delivering what the panel can actually show.
Frame pacing is excellent. 92% of your frames landed within 10% of the median. Motion will feel smooth and consistent, even during quick movements.
Watch the 1% Low to average gap. Your worst frames sit at 96 FPS versus 142 average. That is healthy but not perfect. Closing background apps would help close that gap.
Zero severe stutter events detected. Your system kept pace throughout the test with no major hitches. That is the sign of a well-tuned setup.

What each frame rate actually means

Numbers are easy to compare. Feel is harder. Here is what each tier in the race above translates to in plain language, written for normal people who want to know if their setup is good enough.

240
FPS
Pro reaction speed
Elite tier
4.17 ms per frame · flagship GPU territory · needs a 240Hz display
At 240 FPS, your screen refreshes a new image every 4.17 milliseconds. That is roughly four times faster than 60 FPS. You will not consciously count the difference, but your eyes will track fast motion with almost no blur, and your hands will feel like they are reacting before you decide to react. This is the level competitive players chase.
Best for: Valorant, CS2, Apex Legends, and other twitch shooters where reaction time decides the round.
144
FPS
Esports standard
Excellent tier
6.94 ms per frame · mid to high-end GPU · needs a 144Hz display
144 FPS is the sweet spot for most serious gamers. Each frame lands in just under 7 milliseconds, short enough that motion feels effortless and fast camera turns stay crisp. The jump from 60 to 144 FPS is instantly noticeable to almost everyone. The jump from 144 to 240 is subtler, which is why this tier hits the best balance for price, performance, and smoothness.
Best for: Competitive gaming on a budget, fast-paced shooters, and anyone who wants smooth motion without flagship-tier hardware.
120
FPS
Console flagship
Very smooth
8.33 ms per frame · PS5 and Xbox Series X Performance Mode · needs a 120Hz display
120 FPS is the level most current-gen consoles target in Performance Mode. Each frame takes around 8 milliseconds, which is twice as fast as 60 FPS. You get clearly fluid motion without needing the most expensive GPU on the market. For couch gaming and shooters on a TV or modern monitor, this is the new baseline for feeling fast.
Best for: Console gamers and PC players who want noticeably smoother motion than 60 FPS without chasing a 144Hz monitor.
60
FPS
Smooth gaming baseline
Good tier
16.67 ms per frame · runs on almost any modern PC · needs at least a 60Hz display
60 FPS has been the gold standard for smooth gameplay for over a decade, and it still holds up. Each frame lasts about 16 milliseconds, which is fast enough that motion looks fluid for single-player adventures, racing, strategy, and casual play. If your test result lands here, you are in solid shape for most games at standard settings.
Best for: Story-driven games, MMOs, strategy, racing, and everyday gaming where reaction time is not life or death.
30
FPS
Cinematic floor
Choppy in fast motion
33.33 ms per frame · budget hardware or demanding settings · works on any display
At 30 FPS, each image hangs on screen for over 33 milliseconds before the next one shows up. Films get away with this because the camera moves in calm, predictable ways and natural motion blur fills the gaps. Games do not get that luxury. During fast aim or quick turns, you will see things visibly jump rather than glide. It is playable, just not smooth.
If you land here: Try lowering in-game graphics settings, enabling hardware acceleration in your browser, or checking for thermal throttling before assuming you need a hardware upgrade.

Understanding Your Results

Four key numbers and what each one actually means in plain language.

Average FPS
Your overall performance across the whole test. The headline number people quote, but not the full story.
1% Low FPS
Your worst 1% of frames averaged together. Lower than your average means stutters during fast motion.
0.1% Low FPS
Your very worst moments. Big drops here mean noticeable hitches that you would feel in the middle of a fast game.
Frame Time (ms)
How long each frame took to render. Lower numbers feel smoother. 16.67ms is 60 FPS, 6.94ms is 144 FPS.

Common Issues and How To Fix Them

If your numbers look off, one of these is almost certainly the cause. Each row shows the symptom, what it actually means, and what to try first.

Issue What it means How to fix it
Low Average FPS
Overall performance is below what your monitor or device is rated for.
Try this: Lower graphics settings, close background apps, or check if hardware acceleration is enabled in your browser.
Learn more
High 1% Low or stutter
Frequent dips below your average that cause noticeable choppiness during motion.
Try this: Check CPU and GPU temperatures, reduce background load, and make sure your GPU drivers are up to date.
Learn more
High 0.1% Low
Rare but extreme frame drops that interrupt smooth motion at the worst moments.
Try this: Check for thermal throttling, system bottlenecks, or storage activity from a different app eating resources.
Learn more
High frame time
Frame delivery is inconsistent, making motion feel uneven even when the average looks fine.
Try this: Enable V-Sync or G-Sync, lock your frame rate just below your monitor refresh, or update display drivers.

Frame Rate vs Refresh Rate:
What Is The Actual Difference?

Two numbers. Two jobs. One smooth experience. Here is the plain-English breakdown of what each one actually does, why the difference matters, and how to know which one is holding your setup back.

FPS 144 frames / sec
VS
Hz 144 refreshes / sec

Quick Answer

Frame rate (FPS) is how many frames your computer creates each second.

Refresh rate (Hz) is how many times your monitor updates the image each second.

Best experience happens when FPS is close to Hz.

1 How It Works

Two Jobs, Working Together

Your computer creates the frames. Your monitor displays them. Both halves need to keep up with each other for the experience to feel smooth.

5 Troubleshooting

When Things Feel Off

Three of the most common issues, what each one really means, and exactly what to try first to fix it.

Choppy Gameplay

  • FPS too low
  • System bottleneck
  • Graphics settings too high
Fix:Lower settings, close background apps, or consider hardware upgrade.

Silky Smooth Motion

  • FPS matches or exceeds Hz
  • Stable frame pacing
  • Low input lag
Fix:Keep FPS steady, enable a high refresh rate, lock the cap just below Hz.

Screen Tearing

  • FPS and Hz out of sync
  • V-Sync turned off
  • Frame pacing inconsistent
Fix:Enable V-Sync, G-Sync, or FreeSync to lock the two values together.

Common causes include background apps, thermal throttling, driver issues, or changes in your in-game settings. Close heavy apps, check your temperatures, update your graphics drivers, and use the Troubleshooting Center below for the full fix list.

Yes. Higher FPS means frames arrive faster, so your latest input shows on screen sooner. At 240 FPS you save about 12 ms compared to 60 FPS, which is a meaningful edge in competitive play.

Frame time is how long each frame takes to render, measured in milliseconds. A steady frame time matters more than a high FPS average. Consistent 16 ms beats bursty 8 ms with spikes every time, because smoothness is about consistency.

Yes. The test runs in any modern browser on iOS, Android, Windows, Mac, and Linux. Just open the page and start. Mobile numbers will be lower than desktop, which is completely expected.

FPS is how many frames your computer creates each second. Refresh rate is how many frames your monitor shows each second, measured in Hz. The smoothness you experience is limited by whichever is slower. A fast monitor with a slow computer is wasted, and so is the reverse.

60 FPS is the comfortable baseline for most games. 120 to 144 FPS feels noticeably smoother and is the sweet spot for most gamers. 240 FPS and above mainly benefits competitive shooters. Aim for an FPS that matches your monitor's refresh rate.

The extra frames get discarded, and you may see screen tearing, an ugly horizontal split in the image during fast motion. Capping your FPS slightly below your refresh rate, or using V-Sync, G-Sync, or FreeSync, keeps the two in sync and removes the tearing.

Open our Refresh Rate Test and it auto-detects your Hz in a few seconds. If the result is lower than your monitor's rated spec, check your operating system display settings and confirm the refresh rate is set to its maximum.

For gaming, yes. The jump from 60 Hz to 144 Hz is the most noticeable monitor upgrade most people will ever feel. Motion looks dramatically smoother and aiming feels more responsive. Just make sure your computer can actually push enough FPS to use the extra refresh rate.

High average FPS with stutters means your frame time is inconsistent. A few slow frames mixed into fast ones creates visible hitching. Look at your 1 percent low numbers, not just the average. Closing background apps and capping your FPS often smooths frame time out.

1 percent low is the average of your slowest one percent of frames. It tells you how bad the worst moments are. Two systems with the same average FPS can feel completely different if one has poor 1 percent lows. Always check this number, not just the headline average.

Raise your FPS, use a high refresh rate monitor, enable a low-latency mode in your graphics driver, use a wired mouse with a high polling rate, and turn off unnecessary post-processing. Each step shaves a few milliseconds off the total input-to-screen delay.

You can measure your total reaction latency with our Mouse Polling Rate Test and related input tools. True display input lag needs specialized hardware, but the browser tools give you a solid picture of your overall input chain.

Chrome and Microsoft Edge generally give the most accurate and consistent results because of their reliable timing APIs. Firefox is close behind. Safari can read slightly lower due to its conservative high-precision timer policy. Chrome is the safe recommendation.

They can. Heavy extensions run scripts in the background and steal CPU time, which lowers your test numbers. For the cleanest reading, run the test in an incognito or private window with extensions disabled. Also make sure hardware acceleration is turned on in your browser settings.

It can happen occasionally when V-Sync is off and the browser renders a burst frame just before the monitor sync. It is a quirk of how browsers expose frame timing, not a sign anything is wrong. Run the test a couple more times and the numbers should settle.

Laptops throttle hard on battery to save power, and many drop their refresh rate too. For the real picture, plug into the wall and set the power plan to High Performance before testing. The difference between battery and plugged-in can be dramatic.

Yes. Modern phones run at 90, 120, or 144 Hz, and the test shows which mode your phone is currently using. Note that phones drop to 60 Hz aggressively to save battery, so plug in or disable battery saver for an honest reading.

Update your graphics drivers, close background apps, lower in-game graphics settings, make sure your computer is not overheating, and confirm hardware acceleration is enabled. If FPS is still low across every game, your graphics card may simply be the bottleneck.

Absolutely. When a CPU or GPU gets too hot it throttles itself to cool down, which causes a sudden FPS drop a few minutes into a session. Clean the dust out of your vents, improve airflow, and consider repasting older hardware if the drops keep happening.

Often yes. Capping FPS slightly below your refresh rate reduces screen tearing, lowers power draw and heat, and produces a steadier frame time. A capped, stable 141 FPS on a 144 Hz monitor usually feels smoother than an uncapped 200 FPS that swings around.

Shadows, anti-aliasing, and view distance are usually the heaviest settings. Lowering those three gives the biggest FPS jump for the least visual loss. Resolution scaling is the next lever if you still need more frames.

The test uses the browser requestAnimationFrame and performance.now() APIs to count rendered frames and measure exact frame timing. Everything runs locally in your browser. It measures browser frame rate, which is a great health check for your display chain.

The test is 100 percent free with no signup. All measurements run locally in your browser and no test data is sent to any server. Read the full details on our Privacy Policy page.
