In a game, it usually describes how quickly your computer creates frames; in a camera or video file, it describes the recording or playback rate. A monitor’s refresh rate, measured in hertz (Hz), is a separate limit on how often the screen can update.
Understanding the difference between FPS, frame time and refresh rate explains why 120 FPS can feel smoother than 60 FPS, why a 144-Hz display cannot create missing frames, and why a high average FPS can still stutter.
What is a frame?
A frame is one complete still image in a sequence. Showing successive images rapidly creates the perception of motion, but the motion is still made from discrete pictures. At 30 FPS, 30 frames are presented during one second; at 60 FPS, there are 60; at 120 FPS, there are twice as many temporal samples as at 60 FPS. Perceived fluidity also depends on frame spacing, motion blur and display behavior. Microsoft’s technical definition describes frames as still images used in film and digital video (Microsoft technical definition).
FPS, frame time and refresh rate
FPS is a rate of frame production or presentation. The inverse is frame time: how long each frame takes. Use these equations:

FPS = frames ÷ secondsFrame time (milliseconds) = 1,000 ÷ FPSFPS = 1,000 ÷ frame time (milliseconds)
| FPS | Approximate frame time |
|---|---|
| 24 | 41.67 ms |
| 30 | 33.33 ms |
| 60 | 16.67 ms |
| 90 | 11.11 ms |
| 120 | 8.33 ms |
| 144 | 6.94 ms |
| 165 | 6.06 ms |
| 240 | 4.17 ms |
| 360 | 2.78 ms |
Doubling 60 to 120 FPS therefore halves the interval between frames, from about 16.67 ms to 8.33 ms. That can improve motion and responsiveness, but it does not guarantee that every frame reaches the display at an even interval.
Refresh rate is the display’s update capability, measured in Hz. A 60-Hz screen can refresh 60 times per second; a 120-Hz screen can refresh 120 times. Microsoft and NVIDIA distinguish this display capability from application performance (Microsoft refresh-rate guide; NVIDIA refresh-rate reference).
| Source FPS | Display refresh | What it means |
|---|---|---|
| 60 | 60 Hz | Roughly one new frame per refresh when pacing is consistent. |
| 120 | 60 Hz | The game may render frames the display cannot show distinctly; synchronization determines which are presented. |
| 60 | 144 Hz | The monitor has unused capacity and may repeat frames or show them at uneven intervals. |
| 144 | 144 Hz | A close match, but frame-time spikes can still cause stutter. |
A display cannot invent additional game or video frames. Apple’s display API likewise treats maximum supported frames per second as a screen property separate from an application’s output (Apple documentation).
What does FPS mean in gaming?
In games, FPS normally means the number of frames the CPU and GPU render each second. The result changes with resolution, ray tracing and other settings, scene complexity, drivers, thermal limits, background tasks and any frame-rate cap. A counter may measure rendered, submitted or displayed frames, so it is not always a direct measurement of what your eyes receive. NVIDIA FrameView lists average FPS, 1% lows, rendered FPS, displayed FPS and latency-related metrics (FrameView guide).

Average FPS versus frame pacing
Average FPS hides individual frame durations. A game averaging 120 FPS can still hitch if occasional frames take as long as 45–60 FPS frames. Frame pacing is the consistency of the intervals; two systems with the same average can feel very different.
1% low FPS summarizes performance near the slower end of a run. It helps expose dips, but it is not a complete quality score: frame-time graphs, the cause of spikes and displayed-frame behavior still matter.

Input latency
Higher FPS can shorten the wait between input sampling and a newly rendered frame when the rest of the pipeline is fast. Total latency also includes CPU work, GPU queues, synchronization, display scanout, monitor response, peripherals and network delay. NVIDIA notes that frame-rate limiting can reduce latency in some situations, but the useful cap depends on the game, hardware and whether you are trying to save power, reduce latency or stay inside a VRR range (NVIDIA frame-rate guidance).
V-sync, VRR, tearing and stutter
- Screen tearing: parts of different frames appear together because presentation and refresh are unsynchronized.
- V-sync: coordinates frame presentation with refresh cycles, reducing tearing but potentially adding latency or waiting.
- Variable refresh rate (VRR): lets a compatible display vary its refresh timing within a supported range to follow frame delivery.
- Stutter: uneven delivery, often caused by frame-time spikes, even when the average FPS is high.
NVIDIA describes G-SYNC and related settings as ways to reduce tearing while limiting stutter and latency; VRR cannot make a game render faster or hide severe spikes, and it stops helping outside the display’s operating range (NVIDIA Control Panel reference).

For a camera or video file, FPS is the capture or encoded playback rate. Common choices include:
- 24 FPS: widely used for cinematic production, with motion character influenced by exposure and blur.
- 25 FPS: common in video systems associated with 50-Hz timing.
- 30 FPS: a common general-purpose rate.
- 50 or 60 FPS: useful for smoother action, sports, gameplay and demonstrations.
- 120 FPS and above: primarily useful for specialized high-frame-rate presentation or slow motion.
These are production choices, not a ranking in which one rate is always superior. Adobe explains how frame rate and motion blur shape the visual result (Adobe frame-rate overview). Frame rate is separate from shutter speed or shutter angle, exposure time, motion blur and playback speed: changing FPS alone does not determine how much blur appears in each image.
Why 29.97 FPS appears
Some systems represent rates as ratios rather than whole numbers. Microsoft’s media API lists 30 FPS as 30/1 and 29.97 FPS as 30,000/1,001 (Microsoft MediaRatio documentation). The difference matters for editing, broadcast timing and audio synchronization.
Capture FPS, timeline FPS and delivery FPS
120-FPS footage can be played at 120, conformed to a 60- or 30-FPS timeline for slow motion, or converted by dropping, blending or interpolating frames. On a 30-FPS timeline, 120-FPS capture provides four times as many captured frames for slow motion when conformed correctly. YouTube identifies high-frame-rate uploads alongside resolution, such as 1080p60, and requires the source to have been uploaded or streamed at that rate (YouTube Help).

Why higher FPS can look smoother
More frequent frames reduce the distance in time between updates during camera or object movement. The benefit is strongest when frame times are consistent and the display can refresh at the source rate. A stable 60 FPS can look better than an erratic 100 FPS. Resolution, graphics quality, response-time behavior, motion blur and synchronization all contribute to what you perceive.
Does higher FPS mean better image quality?
No. FPS describes temporal frequency, not resolution, sharpness, color, HDR, textures or detail. A 4K video at 30 FPS may contain more spatial detail than a 1080p video at 120 FPS, while the 120-FPS version may look more fluid and responsive. Evaluate FPS with resolution, image quality, latency, refresh rate, response time, VRR, codec and bandwidth.
FPS, bitrate, storage and bandwidth
Higher FPS generally means more frames must be encoded, processed, transmitted or stored. It does not automatically double file size: resolution, codec, bitrate, keyframe interval, scene motion, color depth and chroma format also determine data use. If bitrate stays fixed, more frames share the same data budget; if quality per frame stays fixed, total bitrate and storage may rise.
What FPS should you use?
| Use case | Practical starting point | Why |
|---|---|---|
| Film-style video | 24 FPS | Conventional cinematic motion and blur characteristics. |
| General video | 30 FPS | A common compromise for everyday footage. |
| Sports, action and gameplay | 60 FPS | More frequent updates for fast movement. |
| Casual gaming | 60 FPS | Often sufficient for slower-paced play. |
| Responsive PC gaming | 90–165 FPS | Useful when hardware and a matching high-refresh display can sustain it. |
| Competitive gaming | 144–240 FPS or more | Relevant to players who can maintain it and have a suitable display. |
| Slow motion | 120 FPS or higher capture | Provides extra frames that can be conformed to a lower playback rate. |
Choose a target by content, display, responsiveness, sustainable hardware performance, recording limits, visual style and cost. There is no universal human-vision cutoff at which motion becomes “real.”
Why high FPS can still look bad
The monitor is stuck at 60 Hz
Verify the operating-system refresh setting, cable, port, dock or adapter, and the monitor’s mode. A game counter can report 200 FPS while a 60-Hz display presents far fewer distinct updates.
A 144-Hz monitor feels like 60 Hz
- The operating system or game is set to 60 Hz or 60 FPS.
- The connection cannot carry the chosen resolution and refresh rate.
- VRR is disabled or the frame rate is outside its range.
- Frame pacing is poor, or motion blur and ghosting are being mistaken for low FPS.
- A compatibility or power-saving mode is active.
The counter is high but the game stutters
Inspect frame-time graphs and 1% lows. CPU spikes, shader compilation, asset streaming, background processes and thermal throttling can produce uneven delivery.

The recording is less smooth than the game
Capture software, the capture device, encoder or editing timeline may run at a lower rate than the game. Elgato documents workflows in which 120-, 144- or 240-Hz input is recorded as a 60-FPS file (Elgato capture utility documentation).
A 240-Hz mode is unavailable
Check resolution and color depth, HDMI versus DisplayPort capability, cable bandwidth, GPU outputs, laptop or dock limits, monitor firmware and input mode. A headline refresh rate may not be available at every combination.

Elgato says the source, display and capture card must all support 120 Hz, along with the rest of the signal chain (Elgato 120-Hz requirements).
High-FPS footage looks unnatural
Check for a mismatched timeline, duplicated or interpolated frames, an incorrect playback rate or an unusually fast shutter speed that creates sharp, staccato motion.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.How to check FPS and refresh rate
- Enable the game’s built-in FPS counter, if available.
- Use your operating system’s display settings to confirm the active refresh rate, not just the monitor’s advertised maximum.
- For stutter diagnosis, use a performance overlay or benchmark that reports frame time and 1% lows, such as NVIDIA FrameView.
- In recording software, verify the actual capture and output FPS; do not assume they match the game’s counter.
Buying around FPS: what matters
Do not buy a monitor, GPU or capture card merely because it advertises a larger number. Match the purchase to content type + target resolution + sustainable FPS + display refresh + synchronization + capture/export limits + budget.
- Monitor: check native refresh at your desired resolution, VRR range, ports, bandwidth, response behavior and panel quality.
- GPU or PC: consider game-specific performance, CPU limits, VRAM, cooling, power and whether upscaling or frame generation fits your priorities.
- Capture card: distinguish passthrough refresh (what you play) from capture FPS (what is recorded) and stream/export FPS. Elgato’s Game Capture 4K X product page describes high-refresh capture capabilities subject to the complete setup.
- Editing software: prioritize mixed-frame-rate timelines, conforming and export controls. Adobe Premiere Pro’s GPU guidance covers accelerated editing tasks and current drivers (Premiere Pro; Adobe GPU requirements).
- Benchmarking: a tool such as NVIDIA FrameView is useful for comparing settings or diagnosing stutter, but unnecessary if you only need to confirm approximately 60 FPS.
Frequently Asked Questions
Is FPS the same as Hz?
No. FPS describes frames produced or encoded by a game or video source; Hz describes how often a display can refresh.

Can a 60-Hz monitor display 120 FPS?
The game can render 120 FPS, but a 60-Hz monitor cannot show 120 distinct refreshes each second. Synchronization determines which frames are presented.
Is 60 FPS good for gaming?
It is a broadly playable target, especially for slower-paced games, provided frame pacing is consistent.
Why does high FPS stutter?
Average FPS can hide long frames. Check frame-time graphs, 1% lows, CPU or GPU spikes, shader compilation, streaming and thermal limits.
Does FPS affect video quality?
It affects motion sampling, not resolution, sharpness or color. Codec, bitrate and resolution are separate quality factors.
