What Is an FPS Test?
FPS stands for frames per second - simply put, it's how many pictures your screen shows you every single second. The higher the number, the smoother and more responsive everything looks. Think of it like a flipbook: the more pages you flip per second, the more fluid the animation.
An FPS checker checks that number live, right in your browser. It tells you whether your display is running at full performance or quietly underperforming. No downloads, no sign-ups - open the page and your result appears in seconds.
Who Should Run an FPS Check?
Professional display testing for every user.
Choppy Screen
Run a quick frame rate test to see if your display is actually dropping frames.
New Monitor
Verify your new 144Hz display is actually running at its advertised speed.
Stuttering Video
Identify whether it's a hardware limitation or a software bottleneck.
A/B Benchmarks
Test before and after changing settings or updating drivers to see real impact.
How to Run Your FPS Test - in 3 Simple Steps
It takes about 10 seconds. No sign-up, no software, no settings to fiddle with.
01
Just open the page
Visit fpstest.app on the device and browser you use daily. The test starts automatically.
02
Let it settle
Give the numbers a few seconds to stabilize to get the most accurate frame rate reading.
03
Compare the rate
If your FPS matches your monitor's Hz, you're at peak performance. If not, check our fixes below.
What Is a Good FPS for Me?
Benchmarks tailored for different usage scenarios.
| Use Case | Experience | Target FPS |
|---|---|---|
| Browsing & Video | Perfectly watchable, standard motion. | 30 FPS |
| Everyday Use | Smooth and comfortable - the standard sweet spot. | 60 FPS |
| Gaming & Creative | Noticeably fluid, much quicker response times. | 120 - 144 FPS |
| Competitive Esports | Ultra-smooth - every millisecond provides an edge. | 240+ FPS |
Why Is My FPS Lower Than Expected?
Common bottlenecks and how to quickly resolve them.
1
Display Settings Check
Your monitor might be hardware-capable of 144Hz but restricted by OS settings. Access your display properties and ensure the refresh rate test matches your hardware's maximum capability.
2
Browser Resource Drain
Heavy background applications and dozens of open tabs compete for GPU resources. Close unnecessary software and re-run your FPS checker to see immediate improvements.
3
Update Graphics Drivers
Outdated GPU drivers are a major cause of inconsistent frame delivery. Check for updates from NVIDIA, AMD, or Intel to ensure your system communicates efficiently with your display.
4
Performance Power Profiles
Laptops frequently throttle performance to conserve battery. Switching to a "High Performance" power profile removes these caps, allowing your frame rate test to hit its true potential.
Frequently Asked Questions
Clear answers to your most common technical queries.
Is this FPS test accurate?
Yes. Our tool utilizes high-precision browser APIs to measure the exact time between frame draws. This results in a real-time reflection of how your browser and hardware are currently delivering frames, rather than a synthetic estimation.
What's the difference between FPS and refresh rate?
Refresh rate (Hz) is the hardware capability - how many times per second your monitor can refresh. FPS is the software delivery - how many frames are actually being generated. To avoid "stuttering," your FPS should ideally match or exceed your refresh rate.
Can I use this FPS checker on my phone?
Absolutely. Modern smartphones with 90Hz, 120Hz, or even higher displays often drop to 60Hz to save power. Using this refresh rate test on mobile is the best way to verify if your device is actually using its pro-motion capabilities.
Is 60 FPS still good enough?
For standard productivity, browsing, and watching cinema, 60 FPS provides a perfectly smooth experience. However, once you experience 120Hz or higher, standard 60 FPS may feel "slow" or sluggish by comparison. It remains a solid baseline for most users.
