Understanding frame rates

Common FPS levels and what they feel like

Frame rate is the number of frames rendered per second. Use our frame rate test to measure your FPS in real-time. Higher FPS reduces motion judder and improves perceived smoothness. This FPS test helps you understand your device's true performance.

Gaming console and controller setup for FPS testing

Why frame rate matters

Higher FPS delivers smoother motion and faster response times. Whether you're gaming, streaming, or working, understanding your device's frame rate helps optimize your experience.

24 FPS

Cinematic look for films and traditional storytelling. Used in most Hollywood movies, creating a classic, immersive viewing experience with natural motion blur.

30 FPS

Standard for broadcast TV, streaming platforms, and web video content. Balances smooth playback with reasonable file sizes for YouTube, Netflix, and live streams.

60 FPS

Smooth motion ideal for gaming, sports broadcasts, and action content. Dramatically reduces motion blur and input lag compared to 30 FPS.

90 FPS

Very smooth motion commonly used in VR headsets and fast-paced games. Reduces motion sickness in virtual reality by minimizing latency between head movement and display update.

120 FPS

High-refresh gaming with noticeably reduced motion blur and input latency. Popular among competitive gamers and owners of 120Hz+ monitors or phones.

240 FPS

Ultra-smooth motion for competitive esports and professional gaming. Provides the lowest input lag and clearest motion clarity during fast tracking and flick shots.

FPS vs Hz

Frame rate and refresh rate are related, not identical

FPS is how many frames your device renders each second. Refresh rate (Hz) is how often your display updates. A high-Hz monitor can only show what your device actually renders. Our frame rate test measures both values simultaneously.

People also call this an FPS tester, frame rate checker, FPS test online, or refresh rate test; this page covers those use cases in one place.

Frame Rate (FPS)

Output from your GPU/CPU. Drops here show up as stutter or uneven frame pacing.

Refresh Rate (Hz)

Display capability. Higher Hz can display more frames when FPS is high enough.

Tips for accurate FPS test results

  • Close heavy tabs or background apps before running the frame rate test.
  • Use fullscreen mode for more consistent FPS test readings.
  • Disable battery saver or power-saving modes.
  • Run the FPS test multiple times and compare averages.

Frame Rate Test Glossary

Key terms for understanding FPS test results

Master these essential concepts to better understand your frame rate test results and optimize your gaming or viewing experience. This FPS test glossary covers all the technical terms you need to know.

Professional gaming PC setup for frame rate testing

Optimize Your Setup

A high-end gaming PC combined with a high refresh rate monitor delivers the best FPS test results. Understanding these terms helps you identify bottlenecks and improve your overall experience.

Screen Tearing

A visual artifact that occurs when your GPU outputs frames faster than your monitor can display them. Our frame rate test helps detect inconsistent frame delivery that causes tearing. V-Sync and adaptive sync technologies like G-Sync and FreeSync help eliminate this issue.

V-Sync (Vertical Sync)

A technology that synchronizes your GPU's frame output with your monitor's refresh rate. While it eliminates screen tearing, it can increase input lag and may cause stuttering if your FPS drops below the refresh rate.

G-Sync / FreeSync

Adaptive sync technologies from NVIDIA and AMD that dynamically match your monitor's refresh rate to your GPU's frame output. They eliminate tearing without the input lag penalty of traditional V-Sync.

Frame Pacing

The consistency of time intervals between displayed frames. A good FPS test should show stable frame pacing. Even at a steady 60 FPS, poor frame pacing can cause perceived stutter.

Input Lag

The delay between your input and the action appearing on screen. Higher frame rates from your FPS test mean lower input lag, which is why competitive gamers prioritize 144Hz+ monitors.

Motion Blur Reduction

A display feature (also called ULMB, DyAc, or ELMB) that strobes the backlight to reduce perceived motion blur. Combined with high refresh rates, it dramatically improves clarity during fast camera movement in games.

FAQ

Common questions

How do I test my FPS? ⌄
Running a frame rate test is simple with our online FPS checker. Click the "Start Test" button and our tool will begin measuring your device's rendering performance in real-time. You'll see live FPS readings, a 30-second rolling chart that updates every second, and estimated refresh rate calculations. This browser-based frame rate test requires no downloads or installation and works on any device including Windows, Mac, and mobile phones.
Is FPS the same as refresh rate (Hz)? ⌄
FPS (frames per second) and refresh rate (Hz) are related but not identical. FPS measures how many frames your GPU or CPU can render per second, while refresh rate (measured in Hertz) indicates how many times your display updates per second. A high refresh rate monitor (144Hz or 240Hz) can only display smooth motion if your device maintains high FPS. This frame rate test helps you identify if your setup is reaching its full potential.
What FPS should I aim for? ⌄
The ideal frame rate depends on your use case and display. For everyday browsing and video playback, 30-60 FPS is sufficient. Gamers should aim for at least 60 FPS for smooth gameplay, while competitive gamers prefer 144 FPS or even 240 FPS on high refresh rate monitors. Our frame rate test helps you measure your current performance and determine if your hardware is delivering the smoothness you need for your specific applications.
Why does my FPS fluctuate or drop? ⌄
FPS drops and fluctuations are normal but can be caused by several factors. Background applications like streaming services, downloads, or other browser tabs consume CPU and GPU resources, lowering your frame rate. Browser throttling occurs when tabs are inactive or when power-saving features are enabled. VSync (vertical synchronization) can cap your FPS to match your monitor's refresh rate. Power-saving modes on laptops and mobile devices significantly reduce performance. Running our frame rate test while closing unnecessary apps and disabling power-saving modes will give you the most accurate results.
Can I compare 30 vs 60 vs 120 FPS? ⌄
Absolutely. Our frame rate test includes visual comparison rows that demonstrate how motion appears at different FPS levels side by side. You can see the difference between 240 FPS (ultra smooth), 120 FPS (smooth), 60 FPS (standard), 30 FPS (noticeable stutter), and 15 FPS (choppy) all in one view. This visual comparison helps you understand why gamers and professionals prefer higher frame rates and whether your current display and hardware setup is delivering the smoothness you need for your specific use case.
Does this work on mobile? ⌄
Yes, our frame rate test works on mobile phones and tablets, but with some limitations. Mobile browsers often cap frame rates to preserve battery life and prevent overheating. iOS Safari typically limits to 60 FPS even on high refresh rate displays, while Android browsers may vary. The test will still function and show you the capped frame rate your device is delivering. For the most accurate frame rate testing, we recommend using a desktop or laptop computer with a dedicated GPU and high refresh rate monitor.
How can I get more stable readings? ⌄
To get stable and accurate frame rate test results, follow these best practices: First, close any unnecessary browser tabs, background applications, streaming services, or downloads that could consume CPU and GPU resources. Second, use fullscreen mode for your browser as it often provides more consistent frame timing compared to windowed mode. Third, disable any power-saving modes or battery-saving features on your device, as these can artificially limit performance. Fourth, disable VSync temporarily if you want to see your maximum potential frame rate. Finally, run the test multiple times and calculate an average to account for normal system fluctuations. Following these steps will ensure your frame rate test reflects your system's true capabilities.
