Free FPS Tester - Live Results

FPS Meter

Measures your actual browser frame rate using requestAnimationFrame. The test runs for 10 seconds and reports average FPS, 1% low, worst frame, frame time, jitter, and a performance score. Results are capped by your display's refresh rate and reflect browser rendering, not in-game FPS.

This fps test uses requestAnimationFrame to measure your actual browser rendering speed. Results update in real time and include average fps, 1% low, worst frame, minimum fps, maximum fps, frame time in milliseconds, jitter, and a stability percentage. The full test runs for 10 seconds and gives you a final performance score. Because browsers sync rendering to your screen, the result is capped at your display's refresh rate.

What Is FPS and Why Does It Matter for Gaming?

FPS stands for frames per second. It measures how many individual images your system renders every second. The higher your FPS, the smoother and more responsive your game feels. A low FPS causes stuttering, lag, and missed shots.

Most competitive gamers aim for 60 FPS minimum. At 60 FPS, motion feels smooth and input lag drops to acceptable levels. Serious FPS players push for 144 FPS or higher because the difference in responsiveness is real and measurable.

Your browser FPS reflects how well your system handles rendering tasks. If your browser struggles to hit 60 FPS on a simple canvas test, your games are likely running below their potential too.

How to Test FPS in Games

Most games have a built-in FPS counter. In Steam games press Shift+Tab and enable the FPS overlay. In Valorant type /fps in console. In Fortnite go to Settings, Video, then enable Show FPS. For any game, you can also use MSI Afterburner or the Windows Xbox Game Bar (Win+G) to display an FPS overlay.

Frame Rate vs Refresh Rate: What Is the Difference?

FPS (frames per second) is how many frames your system produces. Refresh rate (measured in Hz) is how many times your monitor redraws the screen each second. They are not the same thing, and your monitor is the final bottleneck. A 60Hz monitor can only display 60 frames per second no matter how many your GPU pushes, so running 240 FPS on a 60Hz screen wastes most of those frames.

Want to see this with your own eyes? The UFO FPS test animates objects at 30, 60, 120, and 144 FPS side by side so you can spot the difference instantly. To find your screen's real refresh rate, run the monitor Hz detector. And if you care about the dips that cause stutter, the full FPS tester and benchmark reports your 1% low and 0.1% low frame rates.

Your Browser's Frame Rate, Live

This graph measures your browser's real frame rate right now, while you read this page. Scroll, switch tabs, or open other apps and watch how the line reacts. It is capped by your display's refresh rate, so a flat line at 60 or 144 is a healthy result.

Green line = your browser's frame rate, measured live on this page and sampled every half second. It is capped by your display's refresh rate. Yellow reference = 60 FPS. Green reference = 144 FPS.

FPS Benchmarks by Monitor Type

Your monitor refresh rate sets the ceiling for useful FPS. Running 200 FPS on a 60Hz monitor wastes GPU power because your screen can only show 60 frames per second anyway. Match your FPS target to your monitor.

60Hz Monitor

Target: 60 FPS

Standard monitors, office screens, budget displays

144Hz Monitor

Target: 144 FPS

Gaming monitors, esports setups, mid-range builds

240Hz Monitor

Target: 240 FPS

Pro gaming, tournaments, high-end builds

What Affects Your FPS?

  • ▸GPU (graphics card), the biggest factor in gaming FPS
  • ▸CPU handles game logic, AI, and physics calculations
  • ▸RAM speed: faster RAM reduces bottlenecks
  • ▸Background apps: close Chrome tabs and apps before testing
  • ▸Display resolution: higher resolution needs more GPU power
  • ▸Game settings: lower shadows and post-processing for more FPS
  • ▸Browser: Chrome typically scores highest in browser FPS tests

Frequently Asked Questions

An FPS test measures how many frames per second your browser or system renders. Our free fps tester uses requestAnimationFrame to count real frames and shows live results including current FPS, average FPS, min, max, frame time, and stability score.
60 FPS is the minimum for smooth gameplay. Competitive FPS games benefit from 144 FPS or higher. For casual games and browsing, 30-60 FPS is acceptable. Our fps test tool shows you exactly where your system stands.
Click the Run FPS Test button on this page. The test runs for 10 seconds using your browser's requestAnimationFrame API and shows live frame rate data. No download or signup needed.
Frame time is how long each frame takes to render, measured in milliseconds. At 60 FPS the frame time is 16.7ms. At 144 FPS it drops to 6.9ms. Lower frame time means smoother, more consistent gameplay.
Browser FPS and game FPS are separate. Games use your GPU directly via DirectX or Vulkan. Browsers use a sandboxed rendering engine. A browser fps test tells you about your system's baseline rendering performance, not your in-game performance.
Yes. Higher FPS means your system produces frames more frequently, which reduces the time between your input and the visual response on screen. At 144 FPS the theoretical input lag from frame timing alone drops to under 7ms versus 16.7ms at 60 FPS.
Our free UFO Motion Test animates objects at 30, 60, 120, and 144 frames per second on parallel tracks, so the smoothness gap between low and high frame rates is visible at a glance. Find it at fpstest.pro/tools/ufo-test.
The 1% low averages your slowest 1% of frames, capturing the dips and micro-stutters you actually feel while gaming. A high average FPS means little if your 1% low keeps crashing. Our FPS tester reports the 1% low plus your single worst frame so you can spot frame pacing problems.
Yes. This is a 100% free online FPS checker that runs entirely in your browser. There is no download, no signup, and no software to install. Just click Run FPS Test and you get live results on PC, laptop, or mobile.
