FPS Calculator
Test your screen's refresh rate and see your real-time FPS.
Your Current Frame Rate
0
This tool measures your browser's animation frame rate, which is a good indicator of your monitor's refresh rate. Your actual in-game FPS will vary.
About the FPS Calculator
This tool provides a real-time measurement of your browser's Frames Per Second (FPS). This is an excellent way to test your monitor's actual refresh rate (Hz), as browsers are typically capped at that rate. For gamers, knowing your monitor's maximum refresh rate is key to unlocking the smoothest possible gameplay.
Formula Explained
This calculator doesn't use a traditional formula. Instead, it uses a browser API called `requestAnimationFrame()`. This function asks the browser to run a piece of code just before the next screen repaint. By counting how many times this function runs in one second, we can get a very accurate measurement of your screen's refresh rate.
How to Improve Your In-Game FPS
If your in-game FPS is lower than your monitor's refresh rate, here's how to boost it:
Update Graphics Drivers
NVIDIA, AMD, and Intel regularly release driver updates that optimize performance for new games.
Optimize In-Game Settings
Lowering settings like shadows, anti-aliasing, and texture quality can provide a significant FPS boost.
Close Background Apps
Web browsers, streaming apps, and other software can use valuable CPU and RAM resources.
Enable Game Mode
Windows has a "Game Mode" that prioritizes system resources for your game, which can improve performance.
Frequently Asked Questions
What is FPS? →
FPS stands for Frames Per Second. It's a measure of how many consecutive images (frames) are displayed on your screen every second. A higher FPS results in smoother, more fluid motion, which is especially important in fast-paced video games.
What is the difference between FPS and Refresh Rate (Hz)? →
Refresh Rate (measured in Hertz, or Hz) is a property of your monitor—it's the maximum number of times your screen can update itself per second. FPS is the number of frames your computer's graphics card is producing per second. For the best experience, you want your FPS to be at or near your monitor's refresh rate. This calculator measures your browser's frame rate, which is often capped by your monitor's refresh rate.
What is a good FPS for gaming? →
A 'good' FPS depends on the game, but here's a general guide: 30 FPS is often considered the minimum playable frame rate. 60 FPS is the target for most PC gamers, providing a smooth and responsive experience. 120 FPS or higher is ideal for competitive gaming, as it provides the smoothest motion and lowest input lag.
What is V-Sync? →
V-Sync (Vertical Sync) is a graphics setting that synchronizes your game's frame rate with your monitor's refresh rate. This eliminates an issue called 'screen tearing,' where parts of different frames are shown at the same time. The downside is that V-Sync can sometimes introduce input lag.
What are G-Sync and FreeSync? →
G-Sync (from NVIDIA) and FreeSync (from AMD) are adaptive sync technologies. Unlike V-Sync, which forces your game to match the monitor, these technologies allow your monitor to match its refresh rate to your game's FPS in real-time. This provides the benefits of eliminating screen tearing without the input lag, resulting in a very smooth gaming experience.
