FPS Visualiser

1.00x

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

60 FPS(16.67ms)

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

About this tool

The FPS Visualiser 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, so motion looks substantially smoother and input feels 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, yes, 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. 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 are higher contrast, so frame-to-frame differences are more obvious, making 30 FPS feel less fluid.
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, while many TVs are 10-20 ms, 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 eye doesn't sample at a fixed rate, and motion smoothness, input latency, and reduction in motion blur are all perceptible up to several hundred frames per second in the right scenarios.
