60 vs 120 FPS: what actually changes
Doubling again, from 16.7 to 8.3 milliseconds per frame. The gain is smaller than 30-to-60 in absolute time saved, yet most people still see it clearly in tracking motion: targets stay readable while the camera moves, and panning across a scene stops smearing into steps. This is the jump modern phones, consoles in performance mode, and 120Hz laptops are selling — and unlike the steps above it, it is one you can verify on the lanes here only if your own display runs at 120Hz or higher; on a 60Hz screen both lanes are capped to the same thing, which is itself the lesson.
| Rate | Frame time | Frames per second |
|---|---|---|
| 60 FPS | 16.67 ms | 60 |
| 120 FPS | 8.33 ms | 120 |
| Difference | 8.33 ms saved per frame | 60 more frames |
One rule governs everything on this page: a display can only show as many frames as it refreshes. If your monitor runs at 60Hz, the 120 FPS lane above is being capped to 60 by your screen itself and the two will look the same — run the refresh rate test to see your true rate before concluding anything about your eyes. And if you are deciding where upgrade money goes, pair this page with the FPS calculator: the monitor only helps if your hardware can feed it, in the games you actually play.
How to compare honestly
- Track the disc with your eyes rather than staring at the screen — motion clarity differences live in tracked movement.
- Use the Fast lane speed: differences widen as speed rises, which mirrors fast camera movement in games.
- Compare the top pair, then compare each against the Your Rate lane to place your own display on the ladder.
- Re-run on any other display you own — a phone with a high-refresh screen often shows the gap a desktop monitor cannot.
Frequently asked questions
Can you see the difference between 60 and 120 FPS?
On a display that can show both rates, most people can — the lanes on this page run both side by side so you can judge with your own eyes. Remember the ceiling rule: on a 60Hz screen the 120 lane is capped and will look identical, which is a property of your monitor, not of your eyesight.
How much frame time do I save going from 60 to 120 FPS?
Each frame lasts 16.7 ms at 60 FPS and 8.3 ms at 120 FPS — a saving of 8.3 ms per frame. Smaller savings at higher rates are why each step up the ladder feels less dramatic than the last.
Do I need a new monitor for 120 FPS?
Yes, if yours tops out below 120Hz: a display can never show more frames than it refreshes. Check what yours is actually running at with the refresh rate test before spending anything — a surprising number of high-refresh monitors are still set to 60Hz.
Does higher FPS reduce input lag?
Yes, modestly: a new frame is the earliest moment your input can become visible, so shorter frames shrink the average wait. It is one component of total lag alongside device polling, rendering and display processing.
