Frame Rate Tester

What Is FPS?

FPS stands for Frames Per Second. It describes how many individual frames are produced or rendered during one second.

How to Check FPS Online?

If you’re wondering how to check FPS or how to test FPS, you can run the benchmark directly from your web browser. Use the FPS tester here: Run the online FPS test Then: Select your preferred test duration. Choose a rendering workload. Start the FPS benchmark. Keep the browser tab visible. Watch the real-time FPS counter. Review your average, minimum and peak FPS.

How Does the Browser FPS Test Work?

This browser FPS test uses an animated HTML canvas and the browser’s requestAnimationFrame() system to render and measure frames. requestAnimationFrame() tells the browser to run an animation callback before the next repaint. According to MDN, its callback frequency will generally correspond with the display refresh rate, although browser and device conditions can influence actual results.

What Does Current FPS Mean?

Current FPS is the latest calculated frame-rate measurement. It works much like a real-time FPS counter or FPS meter. You may notice that the value changes while the benchmark runs. Small fluctuations are normal because the browser, operating system and other applications may perform work at the same time. Repeated major drops are more significant than tiny variations.

What Does Average FPS Mean?

Average FPS summarizes performance across the benchmark. For example, your current FPS may move between 57 and 60 while the average remains close to 59 FPS. Average FPS is generally more useful for comparison than one momentary peak.
