FPS Visualizer

Simulate and compare up to four frame rates side by side in real time.

Common comparisons
1.00x

0.1x speed simulates 10x slower perception (60fps → 6fps).

60 FPS(16.67ms)
144 FPS(6.94ms)

Adjust the sliders to see how different frame rates affect the smoothness of motion.

How to use this tool

  1. Pick the frame rates to compare

    Toggle one or more frame rate presets (30, 60, 120, 144, 240, 360 FPS) or enter a custom FPS value. Each selected rate gets its own animation lane running side-by-side at the true relative frame interval.

  2. Press play to start the animation

    The visualizer animates a moving object at each selected FPS simultaneously. At 30 FPS the motion steps are visible; at 144 FPS it is visibly smoother; at 240 FPS only the per-frame blur really gives the difference away.

  3. Compare motion smoothness side-by-side

    Watch the lanes together to feel the gap between common refresh rates. Use the result to decide whether a 144 Hz monitor is worth the upgrade over 60 Hz, or whether 240 Hz over 144 Hz is the right jump for competitive play.

  4. Read the frame time numbers

    Each lane shows the per-frame interval in milliseconds (33.3 ms at 30 FPS, 16.7 ms at 60 FPS, 6.9 ms at 144 FPS, 4.2 ms at 240 FPS). Lower frame time means both smoother motion and lower input latency.

About this tool

The FPS Visualizer animates the same motion at multiple frame rates side-by-side at 30, 60, 120, 144, and 240 FPS so you can actually see how much smoother gameplay gets at each tier. Frame-rate comparisons on YouTube are capped by the video's own frame rate, which means this kind of real-time, in-browser demonstration is the only honest way to judge the difference short of owning the hardware.

Use it to decide whether a 144 Hz monitor is worth the upgrade over your current 60 Hz panel, to evaluate how noticeable the jump from 144 Hz to 240 Hz really is, or to settle arguments about whether "the human eye can even see above 60 FPS" (it can, easily). The animation runs directly on your display, so what you see is exactly what you'd experience in a real game at that frame rate.

Frame time and smoothness

Frame rate is smoothness. At 30 FPS each frame is on screen for 33 ms. At 60 FPS that drops to 16.7 ms. At 144 FPS it's only 6.9 ms. Halving frame time consistently cuts input latency and reduces the sample-and-hold blur that makes fast motion look soft on LCD and OLED panels.

When to use it

Reach for this before buying a new monitor or GPU, when tuning in-game settings to hit a frame-rate target, or when comparing console (often 30-60 FPS) against PC (120+ FPS) versions of the same game. Pair it with the Display Bandwidth Calculator to confirm your cable can carry that frame rate at your target resolution, and the PPI Calculator to weigh pixel density against refresh rate.

Frequently asked questions

Is the difference between 60 FPS and 144 FPS really visible?
Yes, clearly. 60 FPS updates every 16.7 ms while 144 FPS updates every 6.9 ms. This makes motion look substantially smoother and input feel more responsive. Most people see the jump immediately. The perceived gain diminishes beyond 240 FPS.
Do I need a 240 Hz or 360 Hz monitor for competitive games?
For competitive esports titles like CS2 or Valorant, the lower motion blur and faster input pipeline give a measurable advantage. For single-player, story-driven games, 120-144 Hz is usually more than enough.
What's the difference between FPS and refresh rate (Hz)?
FPS is how many frames your GPU renders per second. Refresh rate is how many times per second your monitor redraws the screen. If your GPU outputs 200 FPS to a 144 Hz monitor, you see 144 FPS maximum unless you use G-Sync or FreeSync to match them.
Why does 30 FPS feel choppy on PC but smooth on console?
Consoles typically use motion-blur techniques and frame pacing tuned to 30 FPS output on TVs, which are also further from your eyes. PC monitors sit close and have higher contrast. Because frame-to-frame differences are more obvious, 30 FPS feels less fluid on a monitor.
Is 120 FPS on TV the same as 120 FPS on a monitor?
The frame rate is identical, but response times differ. Gaming monitors have 1-5 ms pixel response times. Many TVs have 10-20 ms response times, which can smear fast motion even at 120 Hz. Look for TVs with a dedicated game mode and low input lag.
Can the human eye see more than 60 FPS?
Yes, the "human eye can only see 30 FPS" myth is false. The human eye does not sample at a fixed rate. Motion smoothness, input latency, and motion blur reduction are all perceptible up to several hundred frames per second in the right scenarios.
How do I find out what Hz my monitor is actually running?
Windows Settings > System > Display > Advanced display shows your configured refresh rate, but that can lie when the wrong cable or GPU port is feeding the panel. The honest check is to measure your display's real frame cadence in the browser with our Detect My Refresh Rate tool, which catches a 144 Hz panel silently running at 60 Hz over HDMI 1.4.
