FPS Comparison - 30 vs 60 vs 120 vs 240 FPS
Compare common frame rates side by side. Use the speed and trail controls to make motion differences easier to see on your display.
Interactive visualizer
Side-by-side FPS motion
The animation is capped by your browser and display. A 60Hz screen cannot visibly present 120 unique updates per second, even when a 120 FPS row is shown.
How to read it
Higher FPS reduces spacing between motion updates
Lower FPS makes moving objects jump farther between frames. Higher FPS creates smaller steps, which usually feels smoother and easier to track.
30 FPS vs 60 FPS
60 FPS halves the frame interval from 33.33ms to 16.67ms, so movement feels more continuous.
60 FPS vs 120 FPS
120 FPS cuts the interval to 8.33ms, but you need a 120Hz or faster display to see the full benefit.
120 FPS vs 240 FPS
The jump is smaller than 30 to 60 FPS, but fast tracking and input response can still improve.
FPS vs refresh rate
FPS is rendered frames per second. Refresh rate is how many times the display can update per second.
Motion clarity
FPS comparison is really a frame time comparison
People search for 30 vs 60 vs 120 FPS because they want to know what actually changes on screen. The answer is frame spacing. Each jump in FPS reduces the time between visual updates, which can make motion easier to track and input feel more responsive.
The largest visible jump for most users is 30 FPS to 60 FPS because frame time drops from 33.33 ms to 16.67 ms. Moving from 60 FPS to 120 FPS cuts it again to 8.33 ms, which is very noticeable on a 120Hz display. Moving from 120 FPS to 240 FPS is still measurable, but the improvement is more dependent on fast motion, display response, input latency, and the viewer's sensitivity.
| Comparison | Frame time change | What users notice |
|---|---|---|
| 30 to 60 FPS | 33.33 ms to 16.67 ms | Biggest baseline smoothness jump |
| 60 to 120 FPS | 16.67 ms to 8.33 ms | Clear high refresh improvement |
| 120 to 240 FPS | 8.33 ms to 4.17 ms | Smaller but useful competitive gain |
FAQ
FPS comparison questions
Can I see 120 FPS on a 60Hz monitor?
Not fully. A 60Hz monitor can only present about 60 unique updates per second. The 120 FPS row still explains frame spacing, but a 120Hz or faster display is needed to see the full visual difference.
Why does 30 FPS look less smooth than 60 FPS?
At 30 FPS, each frame lasts about 33.33 ms. At 60 FPS, each frame lasts about 16.67 ms, so moving objects travel a shorter distance between updates.
Is 120 FPS always better than 60 FPS?
On a compatible display, 120 FPS usually feels smoother for fast camera motion, scrolling, and game tracking. For slow content or a 60Hz screen, the practical benefit is smaller.
What is the difference between FPS and refresh rate?
FPS is how many frames the content produces each second. Refresh rate is how many times the display can update. Smooth motion needs the content, browser, and display to line up.
Why does high FPS still sometimes feel choppy?
Average FPS can hide uneven frame pacing. If frame time spikes or jitter is high, motion can feel uneven even when the average FPS number is high.
Is 240 FPS worth it?
It depends on your display and use case. Competitive players on 240Hz screens may notice better tracking and latency, but many users get most of the visible improvement by moving from 30 to 60 or from 60 to 120.
Does this browser demo match real game performance?
No browser demo can replace a game benchmark. This comparison is for understanding motion clarity and frame spacing. Real games also depend on GPU, CPU, engine, input latency, and graphics settings.
How should I use the speed and trail controls?
Increase speed to make frame spacing easier to see. Turn trails on to exaggerate the distance between updates. Then compare the result with the frame time table.
