What is FPS?

Frames per second (FPS) measures how many picture updates your screen shows every second. Higher FPS makes games and video feel smoother. Using an online fps tester helps you confirm that your screen is smooth, while our monitor ghosting test spots trailing behind moving images.

⏱

Frame Time

Frame time is how many milliseconds each frame takes to render. At 60 FPS, every frame should take about 16.7 milliseconds. Uneven frame times cause stutter, even if your average FPS looks fine. Running a frame rate test helps spot stutter, and you can test input delay with our input lag tool.

Refresh Rate vs Frame Rate (FPS)

Your monitor refresh rate (measured in Hertz, or Hz) is the physical limit for how many frames your screen can draw. A 60 Hz screen cannot show more than 60 FPS. If you have a 144 Hz or 240 Hz screen, use our fps checker alongside our refresh rate test to verify your display settings.

⚙️

Why FPS Varies

Background tabs, GPU power limits, browser power-saving mode, and thermal throttling can lower your frame rate. For competitive gaming where smooth frames pair with quick reactions, test your reflexes with our visual reaction test.

Gaming Performance & Monitor Display

Three live readouts on this fps tester — a digital counter for the exact number, an fps checker dial meter, and a Motion & Hz level showing your matched display rate.

Motion & Hz

This FPS tester measures how many frames per second your browser and monitor display in real time using requestAnimationFrame. It records the exact time between rendered frames to calculate live FPS, average frame rate, and frame consistency.
Most standard computer monitors run at a 60 Hz refresh rate, which caps your browser's frame rate test at 60 FPS. If you have a 120 Hz, 144 Hz, or 240 Hz gaming monitor, make sure hardware acceleration is enabled in your browser settings and your display is set to its highest refresh rate in your operating system.
To get the highest score on this FPS checker, enable hardware acceleration in your browser (Settings → System → Use hardware acceleration when available in Chrome and Edge). Close background applications and unused tabs, update your graphics card drivers, and plug in your laptop charger.
